Theory of Machines

Friction Slide Apparatus (Product Code: SLE/MCE/24) is a bench-top inclined-plane apparatus used to measure the coefficient of friction between pairs of materials in mechanics and theory of machines laboratories. Its ground steel plane locks at any angle within ±45° on a protractor scale, and two composite slider trays let students compare aluminium, steel, nylon and brass surfaces. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Friction Slide Apparatus Used For?

Each slider tray is tied to a weight hanger by a cord that runs over the pulley, and weights are added until the tray just begins to slide up the steel plane. The hanging load at that moment, compared with the tray's weight and the plane angle, gives the coefficient of static friction for that material pair. Loading extra weight into the tray shows students that friction force rises in proportion to the normal force.

Because the plane locks anywhere within ±45°, the same set-up doubles as an exercise in equilibrium of forces on an inclined plane apparatus, resolving weight into components along and normal to the surface. Keep the steel plane and tray faces clean and dry, start each trial from the same position and repeat readings to average out scatter. It is compact mechanics lab equipment in India that suits both engineering and senior physics classes.

Frequently Asked Questions

What does the Friction Slide Apparatus measure?
The Friction Slide Apparatus measures the coefficient of friction between a slider tray and a ground steel plane by finding the hanging load that just starts the tray moving. It also works as an exercise in equilibrium of forces on an incline.

Which materials can be compared on the Friction Slide Apparatus?
The Friction Slide Apparatus comes with two composite slider trays, one with aluminium and steel faces and one with nylon and brass faces. Each slides on the ground steel plane, so four material pairings can be compared in one practical.

What angles can the Friction Slide Apparatus plane be set to?
The steel plane of the Friction Slide Apparatus pivots on its base and can be locked at any angle between ±45°. The angle is read on a semi-circular protractor scale mounted on the unit.

How does the Friction Slide Apparatus keep results accurate?
The Friction Slide Apparatus runs the hanger cord over a pulley and bearing that reduce friction in the pulling system, so the hanging load reflects friction at the tray. Its aluminium base with non-slip feet keeps the unit steady on the bench.

Four Bar Chain Apparatus (Product Code: SLE/MCE/25) is a kinematics teaching unit used to show how a four-bar linkage converts uniform continuous rotation into non-uniform rotation or oscillation, in theory of machines laboratories. Students reposition its pivot joints to change crank radius, oscillation radius and coupling length, then read input and output angles on built-in scales to compare crank-rocker, double rocker and double crank mechanisms. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Four Bar Chain Apparatus Used For?

Four-bar linkages sit inside windscreen wipers, rocking conveyors, pump jacks and countless machine mechanisms, and this unit lets students see exactly how one works. The class turns the drive disk in equal steps, notes the input angle on its scale and reads the matching output angle on the output disk. Plotting output against input reveals the non-uniform motion, the limits of oscillation and the dead-centre positions of the linkage.

Changing the pivot positions then shows how link proportions decide whether the linkage behaves as a crank-rocker, double rocker or double crank — the Grashof condition taught in lectures. Work gently near the extreme positions, tighten the pivots after each change and keep a sketch of every configuration with its readings. For departments sourcing mechanics lab equipment in India, it is a stackable, portable unit that serves several groups in turn.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Four Bar Chain Apparatus. It is produced and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to engineering colleges, polytechnics, technical training institutes, dealers and importers.

Because you deal with the maker, questions about link parts, pivots or matching units for additional benches get answered at source — just ask us. See the ScienceLab profile for company details.

Gear Trainer Demonstrator (Product Code: SLE/MCE/27) is a sliding mesh gearbox demonstrator used to teach how gear ratios change speed and torque through a transmission, in automotive and theory of machines laboratories. It represents a typical three forward ratio and reverse sliding mesh box, with protractor pulleys on the input and output shafts so students can determine and verify velocity and torque ratios. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Gear Trainer Demonstrator Used For?

The sliding mesh box is seldom found on modern cars and survives mainly on heavy commercial vehicles, yet its layout is the one from which most modern gearboxes were developed. That makes it the clearest starting point for students of automobile engineering and machine design. With each ratio engaged in turn, the class turns the input pulley through a measured angle, reads the output rotation on the second protractor and works out the velocity ratio.

Applying known loads at the pulleys then lets students compare torque ratio with velocity ratio and discuss losses between them. Counting teeth to predict each ratio before measuring it is a good check, and the reverse gear shows how an extra gear changes the direction of output rotation. The demonstrator works equally well at the front of a lecture room or on a practical bench, which makes it versatile engineering lab equipment for technical institutes.

What to Specify When Ordering

• Number of demonstrators for lecture and practical use
• Whether you also need an Overdrive and Differential to build a simple transmission — confirm availability with us
• Delivery destination in India or abroad

OEM Manufacturer

Gear Train Model (Product Code: SLE/MCE/28) is a mechanism model used to demonstrate a differential gear train built entirely from spur gears, in theory of machines and automobile engineering laboratories. It combines two planetary gear trains whose sun gears are coaxial, so students can hold either wheel and watch how the remaining gears keep turning. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Gear Train Model Used For?

A differential lets two outputs turn at different speeds from one input, which is why a vehicle's wheels can take a corner without scrubbing. Textbook diagrams can make this hard to picture; this model shows the same function with spur gears only, arranged as two planetary trains sharing a common axis. Holding one wheel fixes its sun gear, and students can watch the other gears keep turning and relate what they see to the kinematic equations of planetary trains.

A good exercise is to drive the model slowly, count output turns with one wheel held and then the other, and compare the results with calculated values. The model also illustrates mechanisms that need two controllable inputs, a topic that links theory of machines with robotics and control. Handle it at low speed and keep fingers clear of meshing gears. It is well suited as engineering lab equipment for demonstration tables and student practicals alike.

OEM Manufacturer

The Gear Train Model is manufactured by Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), which trades as ScienceLab and is the OEM (original equipment manufacturer) of this model. Production takes place at the company's licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414).

Colleges, training institutes, dealers and importers buy it factory-direct, so quotations, repeat orders and questions about replacement gears are handled by the manufacturer — ask us. More background is on the ScienceLab company profile.

Frequently Asked Questions

What mechanism does the Gear Train Model show?
The Gear Train Model shows a differential gear train in which all the gears are spur gears. It is built as a combination of two planetary gear trains whose two sun gears are coaxial, demonstrating differential action without bevel-gear complexity.

What happens when one wheel of the Gear Train Model is held?
When the right wheel of the Gear Train Model is held, the right sun gear becomes fixed while the other gears can still rotate; holding the left wheel fixes the left sun gear in the same way. With both wheels free, all spur gears run.

Where is the principle of the Gear Train Model applied?
The Gear Train Model illustrates mechanisms for situations that require two controllable inputs, as well as the familiar vehicle differential. Students can link its behaviour to planetary gear train theory covered in theory of machines courses.

Pulley Demonstration Set (Product Code: SLE/MCE/29) is a free-standing pulley rig used to demonstrate mechanical advantage, velocity ratio and efficiency with fixed and movable pulleys in school and college mechanics laboratories. Physics teachers and engineering instructors use it to build anything from a single pulley to quadruple-sheave systems on three 81 cm steel rods, loaded with brass slotted masses. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as a complete pulley system lab set in one order.

Specifications

What Is the Pulley Demonstration Set Used For?

Collars with hooks slide onto the horizontal rod to carry the pulleys, and the right-angled clamps hold that rod across the vertical rods. A brass weight hanger carries the load, and slotted masses are added on the effort side until the load just rises. Comparing load with effort gives the mechanical advantage; measuring how far the effort and the load travel gives the velocity ratio, and the two together give the efficiency of the arrangement.

Because the kit contains single, triple tandem and quadruple pulleys plus a wheel and axle, one set covers the whole progression from a simple fixed pulley to block-and-tackle systems and other simple machines, making it practical mechanics lab equipment in India for beginner and advanced classes alike. The base also carries a capstan and an eye hook for cord arrangements. Before loading, tighten the vertical rods with the tommy bar, keep the cord running squarely in each groove and add masses gently so that swinging does not upset the readings.

What to Specify When Ordering

• Number of complete sets needed for your student groups
• Extra cord rolls, if classes re-string the pulleys often (4 rolls come with each set)
• Additional slotted brass masses or weight hangers beyond the standard assortment
• Spare single, triple tandem or quadruple pulleys for replacement
• Delivery location in India or abroad

Rotational Moment of Inertia Apparatus (Product Code: SLE/MCE/30) is a three-string pendulum set-up used to determine the moment of inertia of a rigid body in engineering and physics laboratories. A hanging plate is twisted into torsional oscillation, and a photoelectric sensor with a time counting device measures the oscillation period, so students obtain the period electronically rather than by eye. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Rotational Moment of Inertia Apparatus Used For?

Moment of inertia is the rotational counterpart of mass: it describes how strongly a body resists a change in its rotation, and it depends on how that mass is distributed about the axis. Here the plate hangs from three strings, a small twist sets it oscillating about its vertical axis, and the period of that torsional oscillation is linked to the moment of inertia of whatever the plate carries. Timing the empty plate first and then the plate with a test body lets students separate the body's own moment of inertia.

Moving the same body away from the centre of the plate shows how the axis position changes the result, a direct check of the parallel axis theorem in engineering mechanics classes. For consistent readings, keep the twist small, start the plate without sideways swing, and repeat each timing a few times before averaging. As a moment of inertia kit for Indian colleges and polytechnics, it pairs well with a balance and a vernier caliper, because the calculation needs the masses and dimensions involved.

OEM Manufacturer

The Rotational Moment of Inertia Apparatus comes from ScienceLab as the original equipment manufacturer. Jain Scientific Equipments Private Limited, trading as ScienceLab, builds it at its own licensed factory in Saha, Ambala, Haryana, so engineering colleges, universities, distributors and importers buy direct from the maker rather than from a stockist.

The company is a registered MSME with manufacturing as its major activity (Udyam UDYAM-HR-01-0003714), and export consignments are shipped under Importer-Exporter Code AAECJ8618A issued by DGFT. See the ScienceLab company profile for more background.

Related Theory of Machines Equipment

Working out a moment of inertia also needs masses and dimensions, and the topic links to other rotational and torsional experiments:

• Physical Balance (Digital) — weighs the plate and test bodies used in the calculation.
• Caliper Vernier (Metal) — measures plate radius and body dimensions for the theoretical value.
• Stopwatch, Digital — a manual cross-check of the electronic period reading.
• Vibration Of Spiral Spring Apparatus — another torsional oscillation experiment, using a spiral spring instead of strings.

More rotating-mass and mechanism apparatus is listed in the Theory of Machines category.

Frequently Asked Questions

What method does the Rotational Moment of Inertia Apparatus use?
The Rotational Moment of Inertia Apparatus uses the three-string pendulum method. A plate hung on three strings oscillates about its vertical axis, and the moment of inertia of a rigid body placed on it is calculated from the measured torsional oscillation period.

How does the Rotational Moment of Inertia Apparatus measure the period?
The Rotational Moment of Inertia Apparatus measures the torsional oscillation period with a photoelectric sensor combined with a time counting device. Electronic timing avoids relying on a student's reaction speed with a hand stopwatch, which makes repeated readings more consistent.

Which test bodies come with the Rotational Moment of Inertia Apparatus?
The product listing for the Rotational Moment of Inertia Apparatus does not specify the test bodies or accessories supplied. Please ask through our contact page so that the quotation states exactly which bodies and parts are included.

What can students learn from the Rotational Moment of Inertia Apparatus?
With the Rotational Moment of Inertia Apparatus, students learn the physical meaning of moment of inertia, the three-string pendulum measurement method, and how the mass distribution and axis position of a rigid body change its moment of inertia.

Who manufactures the Rotational Moment of Inertia Apparatus?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Rotational Moment of Inertia Apparatus as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Quotations and spares queries are answered directly by the company that makes it.

Vibration Of Spiral Spring Apparatus (Product Code: SLE/MCE/32) is a wall-mounted torsional oscillator used to study the stiffness and free vibration of a flat spiral spring in theory of machines and mechanical engineering laboratories. Its spring has a listed stiffness of 238 Nmm and a 10 x 1 mm cross-section, and two levers with sliding weights let students change the rotating mass while an integrated 360° scale reads the deflection. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Spiral Spring Vibration Apparatus Used For?

The practical runs in two stages. In the static stage, the metallic rod with its end masses applies a moment that turns the shaft against the spiral spring, and the angle scale shows the resulting deflection, so students can calculate the spring stiffness and read how far the spring was deflected initially. In the dynamic stage the rod is released, the spring-mass system oscillates freely, and the timed period is compared with the value predicted from stiffness and moment of inertia.

Sliding the weights along the two levers changes the moment of inertia without changing the spring, so one unit produces a full series of frequency readings for a graph. The ball-bearing axis keeps friction low, helping the oscillations last long enough to time several cycles. Fix the anodised aluminium plate firmly to a solid wall at a comfortable reading height; it is compact engineering lab equipment for vibration and SHM practicals in India and abroad.

What to Specify When Ordering

• Number of units, for example one per bench or student group
• Wall space for each 200 x 250 mm base plate
• A stopwatch or timer for the oscillation readings, if your laboratory does not already have one

OEM Manufacturer

ScienceLab is the OEM for this apparatus. Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, manufactures it at its own licensed factory at Saha, Ambala, Haryana, India, so it reaches buyers factory-direct rather than through a trading chain.

Technical colleges, TVET institutes, dealers and importers get quotations and technical answers from the source, and requests for replacement levers or weights on existing units go straight to the maker — just ask us. Read about the company on the ScienceLab profile page.

How is deflection read on the Vibration Of Spiral Spring Apparatus?
Deflection on the Vibration Of Spiral Spring Apparatus is read on an integrated angle measuring scale mounted on the axis. The scale covers 360° with a resolution of 1°, and it also shows how far the spring was deflected initially.

How is the Vibration Of Spiral Spring Apparatus installed?
The Vibration Of Spiral Spring Apparatus is built on a wall mounting plate made of anodised aluminium, with a base plate of 200 x 250 mm (width x height). Fix it to a solid wall at eye level so students can read the angle scale comfortably.

Can students change the oscillating mass on the Vibration Of Spiral Spring Apparatus?
Yes. The Vibration Of Spiral Spring Apparatus has two levers with sliding weights, so students can move the weights to change the moment of inertia and record how the natural frequency of the spring system changes with each setting.

Cam Mechanism (Product Code: SLE/MCE/75) is a bench-top demonstration unit used to show how a rotating cam converts uniform rotation into non-uniform follower motion, with or without dwell, in theory of machines laboratories. Students fit one of four cam shapes and one of three engaging members, then read the follower stroke on a 0–30 mm dial gauge against the cam angle on a 360° scale. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Cam Mechanism Used For?

A cam is a shaped disc that pushes a follower through a planned motion as it turns, as in engine valve gear and automatic machinery. On this unit, students set the cam to successive positions on the angular scale and record the stroke on the dial gauge, building a displacement diagram of follower lift against cam angle. Repeating the test with the circular arc, tangent, hollow and asymmetric cams shows how the profile shapes the rise, dwell and return of the follower.

Swapping between the roller plunger, flat plunger and cam follower needs no tools, so the class can compare how each engaging member traces the same profile within one session. From the displacement readings, advanced students can estimate follower velocity and acceleration by differentiating the curve, a standard exercise in a kinematics of machines course. Keep the dial gauge plunger clean and square to the follower to make full use of its 0.01 mm graduation.

OEM Manufacturer

The Cam Mechanism is an OEM product of ScienceLab. Jain Scientific Equipments Private Limited, trading under the ScienceLab name, manufactures it at its own licensed factory at Saha, Ambala, Haryana, India, and sells it factory-direct to engineering colleges, polytechnics, ITIs, dealers and importers.

Because the maker handles each order, questions about extra cams, spare engaging members or repeat orders for more benches can be raised with us directly. The ScienceLab company profile explains more about the company as an engineering lab equipment manufacturer.

Free and Forced Vibration Apparatus (Product Code: SLE/MCE/76) is a vibration trainer used to study free, damped and forced mechanical vibration of a bar-type oscillator in mechanical engineering laboratories. Its electronically controlled exciter runs from 0 to 50 Hz, an oil-filled hydraulic damper gives adjustable damping, and a mechanical drum recorder traces each response on paper. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Free and Forced Vibration Apparatus Used For?

The bar-type oscillator works together with interchangeable coil springs and, depending on the experiment, is left to vibrate freely, slowed by the oil damper, or driven by one of the two exciters. In free vibration tests, students displace the bar, release it and use the drum recorder trace to find the natural frequency; with the damper connected, the decay of successive peaks gives the logarithmic decrement and damping ratio. Changing between the 0.75, 1.5 and 3.0 N/mm springs shows how stiffness shifts the natural frequency.

For forced vibration, the control unit sets the excitation frequency up to 50 Hz, driving the bar through either the imbalance exciter (0–1000 mmg) or the displacement exciter (20 mm stroke). Stepping through the range and recording amplitude reveals resonance, and repeating the sweep at several damper settings shows how damping flattens the resonance peak. This makes the unit core engineering lab equipment for dynamics of machinery courses in India; let the exciter settle at each frequency before taking a trace.

What to Specify When Ordering

Corollis Component of Acceleration Apparatus (Product Code: SLE/MCE/77) is a self-contained water-jet rig used to determine the Coriolis component of acceleration at different rotation speeds and water flow rates in theory of machines laboratories. Water leaves rotating arms with 9 mm and 6 mm orifice diameters, while a 250–2500 LPH rotameter shows the flow and a variable-speed swinging-field motor sets the speed. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Coriolis Acceleration Apparatus Used For?

When a body moves outward along a link that is itself rotating, it gains an extra acceleration at right angles to the link, equal to twice the product of the angular velocity and the sliding velocity. This is the Coriolis component, a key idea in the kinematics of slotted-link and quick-return mechanisms. In this apparatus the moving body is water flowing out along the rotating arms, which makes the effect measurable in a classroom.

A typical session holds the flow steady on the rotameter, runs the arms at several speeds with the speed control unit, then repeats at other flow rates, so students see how the component depends on both angular velocity and flow velocity and compare their results with theory. Because the tank, pump and arms form a closed re-circulating circuit on one powder-coated frame, the rig needs no water supply line, which suits engineering lab equipment rooms in India and abroad. Check the water level before each run and raise the speed gradually.

What to Specify When Ordering

• Power supply version: 230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz, single phase
• Number of units required
• Delivery location, so that the quotation matches your destination

Gyroscope Experiment Manual (Product Code: SLE/MCE/78) is a hand-spun gyroscope apparatus used to demonstrate precession and the gyroscopic couple in theory of machines and physics laboratories. A 250 mm, 1500 g disc runs on dual ball bearings at one end of a tilting shaft, balanced by a movable 1400 g counterweight, and the shaft angle is read on a scale from -40° to +40°. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Gyroscope Experiment Apparatus Used For?

With the disc at rest, students first use the movable counterweight, the spirit level and the thumbscrew to balance the shaft horizontally. They then spin the disc by hand or with the cord and apply the 50 g additional weight to unbalance the shaft: instead of simply dropping, the shaft swings slowly around the vertical axis. This precession is the classic gyroscopic effect, and timing it against the disc speed lets the class compare observed precession with the value predicted from the disc's angular momentum.

Because the dual ball bearings keep the rotation nearly frictionless, the disc keeps turning for long periods, leaving time for several readings from one spin. The open construction lets a whole group watch the shaft's motion, while the inclination scale records how far the shaft tilts. The apparatus links physics lab equipment in India for angular momentum with engineering cases such as the gyroscopic couple on ships, aircraft and vehicles taking a turn.

OEM Manufacturer

ScienceLab is the original equipment manufacturer of this gyroscope. Jain Scientific Equipments Private Limited, known to buyers as ScienceLab, makes it at its own licensed factory at Saha, Ambala, Haryana, India, and dispatches it factory-direct to schools, colleges, dealers and importers.

Static and Dynamic Balancing Apparatus (Product Code: SLE/MCE/79) is a rotating-shaft trainer used to show the difference between static and dynamic imbalance and to practise balancing rotating masses in theory of machines laboratories. Four imbalance masses attach to a smooth shaft at any angular and longitudinal position, and a variable-speed motor with belt drive turns the shaft up to 1400 rpm with a digital speed display. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Static and Dynamic Balancing Apparatus Used For?

A rotor is statically balanced when it stays put in any angular position, yet it can still shake when it spins if its masses lie in different planes along the shaft; that is dynamic imbalance. On this unit, students first arrange the four imbalance masses so the shaft rests in any position, comparing the moment they produce about the shaft with the moment of the imbalance masses. They then run the motor and see whether the shaft turns smoothly or vibrates, which shows why static balance alone is not enough.

The usual exercise is to calculate the angular and axial positions of the masses by the graphical or analytical method taught in dynamics of machinery, set them on the shaft, and confirm the result by running at increasing speed on the digital display. Close the transparent cover before starting the motor and tighten every mass securely. For colleges building a set of mechanics lab equipment in India, it pairs naturally with whirling-of-shaft and vibration apparatus.

OEM Manufacturer

The Static and Dynamic Balancing Apparatus is produced by ScienceLab as the OEM. Jain Scientific Equipments Private Limited, which operates under the ScienceLab name, manufactures it at its own licensed factory at Saha, Ambala, Haryana, India, so universities, polytechnics, laboratory suppliers and importers can buy straight from the source.

Repeat orders and requests for spare imbalance masses or a replacement drive belt are handled by the manufacturer itself; ask us. More information is on the ScienceLab company profile.

Internal Gear Pinion Drive (Product Code: SLE/MCE/80) is a hand-cranked bench-top model used to demonstrate the fundamentals of how an internal gear and pinion drive works in theory of machines and technical training classrooms. The gear train is left open for study between two clear plastic plates, and two dials show rotation so students can compare the movement of the gears. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Internal Gear and Pinion Drive Used For?

In an internal gear drive, a small pinion meshes with teeth cut on the inside of a larger ring gear. Unlike an ordinary external gear pair, both gears turn in the same direction and the centre distance is shorter, which is why the arrangement appears in planetary gearboxes and compact reduction drives. Turning the hand crank slowly lets students watch the teeth engage through the clear plates and see the same-direction rotation for themselves.

Using the two dials, the class can count turns and compare the result with the ratio of tooth numbers, then discuss why internal gearing gives a compact reduction. At 5 kg and 400 x 200 x 300 mm, the model is easy to carry between classroom and workshop, making it handy engineering educational equipment in India for ITI, polytechnic and first-year engineering courses. Wipe the plastic plates with a soft cloth so the mesh stays clearly visible.

OEM Manufacturer

This demonstrator is an OEM product. Jain Scientific Equipments Private Limited, trading as ScienceLab, manufactures the Internal Gear Pinion Drive at its own licensed factory at Saha, Ambala, Haryana, India, rather than reselling a bought-in model.

Whirling of Shaft Apparatus (Product Code: SLE/MCE/81) is a rotor dynamics trainer used to find the critical (whirling) speeds and mode shapes of slender rotating shafts in mechanical engineering laboratories. Six high-strength steel rotor shafts of 3, 6 and 7 mm diameter and 600 or 900 mm length are driven by a 0.37 kW adjustable-speed motor up to 6000 rpm behind a transparent protective cover. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Whirling of Shaft Apparatus Used For?

Every slender shaft has speeds at which it bows outward and whirls, because the running speed coincides with a natural frequency of transverse vibration. Students fit a rotor shaft, raise the motor speed slowly with the potentiometers, and note on the digital display the speed at which the shaft visibly whirls, then compare it with the value calculated from shaft stiffness, mass and support conditions.

Repeating the run with the 3, 6 and 7 mm shafts, the 600 and 900 mm lengths and different bearing spacing shows how diameter, length and support position move the critical speed, while higher speeds reveal the mode shapes of a continuous rotor. The two preselectable speeds make it quick to return to a point of interest. Keep the cover closed and pass steadily through each critical speed; as engineering lab equipment in India for dynamics of machinery, it shows clearly why turbine and pump shafts are designed to run away from their critical speeds.

What to Specify When Ordering

• Power supply version: 230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz, single phase
• Spare rotor shafts, if you expect heavy student use (ask us)

Air Bearing Apparatus (Product Code: SLE/ETM/01) is a bearing trainer used to show how a pressurised air film forms between a spinning shaft and its bush and supports load, in theory of machines and tribology laboratories. Students set shaft speed through a belt-driven motor drive module, load the bush by hand against a load cell, and read film pressure at tappings spaced evenly around the bush on a multichannel digital display. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM engineering lab equipment manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Air Bearing Apparatus Used For?

The apparatus lets students see the pressure distribution that allows a journal bearing to carry load without metal-to-metal contact. With the shaft running at a chosen speed, they read each tapping on the multichannel display, plot pressure against angular position around the bush, and repeat at other speeds and loads. Comparing the area under the pressure curve with the load cell reading links the measured film pressure to the load the bearing supports.

Typical exercises cover how peak pressure and its position shift as load rises, how speed affects the film’s load capacity, and where the film starts to break down at low speed. Bring the shaft up to speed before adding load, increase the hand-operated load in small steps, and let the display settle before recording. This makes it useful engineering educational equipment in India for mechanical engineering, tribology and machine design courses.

What to Specify When Ordering

• Whether the optional frame-mounted data acquisition unit is required (ask us about availability)
• Number of sets for your laboratory
• Whether related bearing apparatus, such as the Journal Bearing Demonstration, should be quoted together

What Is the Governor Apparatus Used For?

A governor regulates engine speed by moving a sleeve, and through it a fuel or steam control, as its rotating masses swing outward. With this apparatus students run each governor across a speed range, record sleeve lift from the sensor at each speed and plot the characteristic curve of lift against speed. Comparing the dead-weight Porter and Proell designs with the spring-loaded Hartnell shows how the controlling force shapes sensitivity and stability.

Further runs add the supplied weights to the Porter and Proell sleeves, or change the Hartnell arm length and rotating mass, and show how the curve shifts, which leads naturally to governor effort, power and hunting. Close the clear dome before starting, since the interlock cuts motor power while it is open, and raise speed gradually as readings are taken. It is core mechanics lab equipment in India for dynamics of machinery syllabi.

Journal Bearing Demonstration (Product Code: SLE/ETM/03) is a floor-standing lubrication apparatus used to show how an oil film builds pressure around a rotating shaft in theory of machines and tribology laboratories. A motor-driven steel shaft turns inside a clear acrylic bearing with an extra-large clearance, and 16 pressure tappings feed a rear manometer panel so the oil pressure head at every point is visible at once. It is produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its lab equipment for technical institutes.

Specifications

What Is the Journal Bearing Demonstration Used For?

Students load the bearing with weights on its arms, run the shaft at a set speed and read the oil pressure head on all 16 manometer tubes at once. The 12 circumferential readings give a polar plot of pressure around the journal, showing where the film pressure peaks and where it falls away, while the four extra tappings show how pressure varies along the top of the bearing and on the vertical plane.

Repeating the test at different speeds and loads, and in both directions of rotation, shows how the pressure pattern follows the running conditions, while the extra-large clearance makes the oil wedge visible through the acrylic. Set the reservoir level before starting, clear any air from the manometer tubes, and let readings stabilise after each change. The unit suits tribology and machine design classes that rely on engineering lab equipment in India.

OEM Manufacturer

This journal bearing demonstration is manufactured by ScienceLab, the trading name of Jain Scientific Equipments Private Limited, which is its OEM. Production and assembly take place at the company’s own licensed factory at Saha, Ambala, Haryana, India, and the apparatus is supplied factory-direct to technical universities, engineering colleges, TVET institutes, dealers and importers in India and international markets.

If you later need replacement manometer tubing, a spare diaphragm or additional sets, the manufacturer can quote them directly — ask us. Company details are on the ScienceLab profile.

Frequently Asked Questions

How many pressure tappings does the Journal Bearing Demonstration have?
The Journal Bearing Demonstration has 16 pressure tappings: 12 equally spaced around the bearing circumference and four more along its topside and on a vertical radial plane, all connected to the rear manometer panel.

How is the bearing loaded?
Students load the Journal Bearing Demonstration by attaching weights to arms connected to the bearing, which is freely supported on the motor shaft. Changing the weights shows how load alters the oil pressure distribution.

Can the shaft run in both directions?
Yes. The control unit of the Journal Bearing Demonstration adjusts motor speed in both directions of rotation, and a display shows the motor speed, so the effect of reversing the shaft on the oil film can be observed.

Is oil included with the apparatus?
Yes, a container of suitable oil is supplied with the Journal Bearing Demonstration. An adjustable reservoir feeds this oil to the low-pressure region at both ends of the bearing during operation.

Why is the bearing clearance so large?
The Journal Bearing Demonstration uses an especially large clearance so the oil in the bearing can be seen clearly through the clear acrylic shell, making the formation of the lubricating film visible to a whole class.

Who manufactures the Journal Bearing Demonstration?
The Journal Bearing Demonstration is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India, and is supplied factory-direct to institutions in India and international markets.

Damper Kit (Product Code: SLE/ETM/04) is a dashpot damping accessory used to add viscous damping to beam vibration experiments on the Free Vibrations Test Frame in theory of machines laboratories. A simple piston disc moving in a cylinder fits to the Test Frame beneath the beam, and the damping level is set by the non-toxic fluid students pour in, which is not supplied. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM and TVET lab equipment manufacturer in India, at its own factory in Ambala.

Key Details

What Is the Damper Kit Used For?

Real machines and structures never vibrate for ever, because friction and fluid resistance remove energy in every cycle. Fitted beneath the beam, the kit’s piston disc has to push fluid aside in the cylinder each time the beam moves, turning an almost undamped oscillation into a decaying one. By comparing successive peaks, students calculate the logarithmic decrement and damping ratio and see how both change with the fluid used.

Start with the cylinder empty to record the undamped response, then repeat with fluids of increasing viscosity that are safe and easy to obtain, keeping the fill level the same each time. Because students may also make their own piston discs, the kit supports project work on how disc size or shape alters damping. It is straightforward engineering educational equipment for vibration and dynamics courses in India.

What to Specify When Ordering

• The Free Vibrations Test Frame, if your laboratory does not already have one (the kit fits to it)
• The beam experiment it will be used with, for example the Free Vibration Of Beam Spring
• Number of kits per laboratory
• Damping fluids are not supplied, so plan to source suitable non-toxic fluids locally

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM that makes this damper kit at its own licensed factory at Saha, Ambala, Haryana, India. Colleges, polytechnics and training institutes, as well as dealers and importers, buy it factory-direct together with the test frame and the vibration experiments it serves.

Institutional and tender buyers registering the company as a vendor can use GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. Replacement piston discs or extra kits can be quoted by the manufacturer on request — ask us, and see the company profile for more about ScienceLab.

Free Vibration Of Beam Spring (Product Code: SLE/ETM/05) is a one-degree-of-freedom vibration experiment used to study how a rigid beam, pivoted at one end and hung from a coiled spring at the other, oscillates in theory of machines laboratories. It mounts on the Free Vibrations Test Frame through a back panel carrying self-aligning pivot bearings and a non-contacting displacement sensor, so oscillations are measured with negligible damping. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM vocational training lab equipment manufacturer in India, at its own factory in Ambala.

Key Details

What Is the Beam Spring Vibration Experiment Used For?

The beam, pivot and spring form the same arrangement found in many machines and in vehicle suspensions, reduced to a single degree of freedom that students can analyse by hand. They can determine the spring constant by static loading to confirm Hooke’s Law, work out the beam’s moment of inertia about the pivot and predict its natural frequency. Displacing the free end and releasing it lets the non-contacting sensor record the oscillation, so the measured frequency can be checked against the prediction.

Because the sensor does not touch the beam, inherent damping is negligible, which makes any added damping easy to see; fitting the separate Damper Kit beneath the beam extends the study to damped motion. The recorded trace also shows the phase difference between displacement and its derivatives, velocity and acceleration, linking the experiment to simple harmonic motion theory. It is a compact piece of mechanics lab equipment in India for dynamics and vibrations courses.

What to Specify When Ordering

• The Free Vibrations Test Frame, if not already in your laboratory (the experiment fixes to it)
• The Damper Kit, if damped vibration is part of your syllabus
• Number of sets per laboratory

Free Vibrations Of A Cantilever (Product Code: SLE/ETM/06) is a vibration experiment used to show how a clamped beam with an end mass oscillates like a mass-spring system, its own stiffness acting as the spring, in theory of machines laboratories. Students set the oscillating length with a sturdy clamp on a back panel that fixes to the Free Vibrations Test Frame, while a non-contacting sensor on two runners follows the tip without touching it. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM laboratory equipment manufacturer in India, at its own factory in Ambala.

Key Details

What Is the Cantilever Vibration Experiment Used For?

A cantilever with an end mass is the simplest model of a structure that vibrates under its own stiffness, from a diving board to an aircraft wing. Students clamp the beam at a chosen length, deflect the tip and release it while the non-contacting sensor records the oscillation; repeating at several lengths shows how frequency falls as the cantilever gets longer. Measured frequencies are then compared with values predicted from the beam’s stiffness and second moment of area.

Because the beam is not a light spring, its own mass affects the result, so the experiment is used to compare simple predictions with Rayleigh’s method and Dunkerley’s method, which account for distributed mass. The trace also shows the phase difference between displacement, velocity and acceleration. Tighten the clamp firmly at each new length, keep the sensor runners in line with the tip, and use small initial deflections for clean, repeatable traces.

What to Specify When Ordering

• The Free Vibrations Test Frame, if your laboratory does not already have one
• Number of cantilever sets needed for your student groups
• Any companion experiments for the same frame, such as the Free Vibration Of Beam Spring

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, manufactures this cantilever vibration experiment as the OEM at its own licensed factory at Saha, Ambala, Haryana, India. Institutions building a vibrations laboratory can source the experiment, the test frame and companion set-ups factory-direct from one manufacturer, whether they are universities, polytechnics, dealers or importers.

Damper Kit For Mass/Spring (Product Code: SLE/ETM/07) is a dash-pot damping accessory used to add viscous damping to a mass-spring vibration experiment, fitting to the guide rods under its platform, in theory of machines laboratories. Its piston disc and cylinder work with easily found non-toxic fluids, so students can move from light to heavy damping simply by changing the fluid. It is produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM scientific equipment manufacturer in India, at its own factory in Ambala.

Key Details

What Is the Mass-Spring Damper Kit Used For?

A mass bouncing on a spring is the textbook single-degree-of-freedom system, and adding a dash-pot turns it into the damped model used for vehicle suspensions and machine mounts. Mounted on the guide rods beneath the platform, the piston disc moves through fluid in the cylinder each time the mass oscillates, taking energy out of the motion. With a thin fluid the platform rings down gradually (underdamped); with a thick one it creeps back without overshooting (overdamped).

When the motion is recorded with a data acquisition system, the displayed data can be fitted to underdamped and overdamped viscous damping models, so students can extract a damping coefficient and compare it with theory. Try a series of non-toxic fluids of increasing thickness, fill the cylinder to the same level each time, and clean the piston disc between fluids. Students may also design their own piston discs, which makes the kit a good base for project work.

What to Specify When Ordering

• The mass-spring experiment the kit will be fitted to (it mounts on the guide rods under the platform)
• Whether data acquisition for fitting damping models is required (ask us about options)
• Number of kits for your student groups

OEM Manufacturer

The Damper Kit For Mass/Spring is manufactured by ScienceLab — the trading name of Jain Scientific Equipments Private Limited — which is its OEM and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Because the related vibration apparatus comes from the same manufacturer, colleges, training institutes, dealers and importers can order the damper and the experiments it serves factory-direct from one source.

Vibration measurements are only repeatable when the structure holding the experiment neither flexes nor rocks. Students, teachers or lecturers fix the back panel of each free vibration experiment to the slotted alloy members, level the frame with its adjustable feet and the spirit level, and then run the test; changing to another experiment means removing one panel and fitting the next.

One frame can therefore serve a sequence of experiments, including the beam-spring, cantilever and damper studies, which saves bench space and makes it practical lab equipment for technical institutes. The storage tray and lid keep tools and small parts of optional experiments together so they are not lost or damaged between classes. Two people can carry the frame around the classroom, but recheck the level with the spirit level whenever it is moved.

Hertzian Contact Apparatus (Product Code: SLE/ETM/09) is a self-contained bench unit used to show how two curved surfaces meet under load, so that measured contact shapes can be checked against Hertz’s original theories in engineering laboratories. Mechanical engineering students use it because the lower pad rotates against a pointer, turning the contact zone from circular to elliptical. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Hertzian Contact Apparatus Used For?

Whenever a ball meets its race, a gear tooth meets its mate or a wheel rolls on a rail, the load passes through a very small patch of contact, and the size and shape of that patch decide the contact stress. This apparatus lets a class see that patch for itself. The hydraulic cylinder presses the two curved pads together, students read the contact outline with the transparent scale, and the result is compared with the size predicted by Hertz theory.

Turning the lower pad changes the relative curvature of the two surfaces, because the upper pad has compound radii. At some angles the contact is circular; at others it stretches into an ellipse, which makes the unit a practical piece of engineering lab equipment in India for tribology, machine design and theory of machines courses. Record the pointer angle for every reading, and leave the pump locknuts at their set position so the maximum pressure stays limited.

OEM Manufacturer

The Hertzian Contact Apparatus is built by Jain Scientific Equipments Private Limited, which trades as ScienceLab, at its own licensed factory at Saha, Ambala, Haryana, India. Because the maker supplies it factory-direct, engineering colleges, polytechnics, dealers and importers deal with the people who assemble the pads, pump and scale — for quotations, repeat orders and replacement parts, ask us.

Frequently Asked Questions

What does the Hertzian Contact Apparatus demonstrate?
The Hertzian Contact Apparatus demonstrates the nature of contact between two curved surfaces under load. Students measure the contact shape and compare it with predictions from Hertz’s original theories, and they see how changing the relative curvature changes the contact zone.

How is the load applied?
On the Hertzian Contact Apparatus SLE/ETM/09, a hand-operated hydraulic pump and cylinder force the two pads together. Locknuts on the threads of the pump limit the maximum pressure, which protects the pads and the rest of the equipment from damage.

Why does the contact zone change from circular to elliptical?
In the Hertzian Contact Apparatus, the upper pad has compound radii, so rotating the lower pad changes the relative curvature at the point of contact. Depending on the angle shown by the pointer, the contact zone is circular or elliptical.

What is included with the Hertzian Contact Apparatus?
The Hertzian Contact Apparatus comprises two pads with curved contact surfaces, a rotatable lower pad with pointer, and a hand-operated hydraulic pump and cylinder. A transparent scale for measuring the contact shape and angle is supplied with it.

Who manufactures the Hertzian Contact Apparatus?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, is the OEM manufacturer of the Hertzian Contact Apparatus SLE/ETM/09. It is produced at the company’s own licensed factory at Saha, Ambala, Haryana, India, and sold direct by the maker.

Cam Analysis Machine (Product Code: SLE/ETM/10) is a motor-driven test machine used to study how a follower responds to a rotating cam at different speeds, spring preloads and follower masses in engineering laboratories. Mechanical engineering students use it because the precision machined heavy steel base carries a high-torque direct-drive variable-speed motor and a flywheel that steadies the drive. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Cam Analysis Machine Used For?

Cams open engine valves, index machine tools and drive packaging lines, and at speed a follower may no longer track the cam profile faithfully. The Cam Analysis Machine lets students explore that behaviour on the bench: they choose a cam and follower, set the motor speed, and watch how the follower responds as the speed rises. The flywheel on the main shaft keeps the drive speed steady even though the torque demand changes through each rotation.

The follower is held against the cam face by its own weight, the weight of the vertical shaft and, when fitted, one of the two compression springs. Changing the spring, adjusting its preload or adding masses changes the force on the cam, so a class can compare several set-ups in one session. This makes it useful mechanics lab equipment in India for theory of machines and machine dynamics practicals.

What to Specify When Ordering

• The number of machines for your laboratory.
• Which cams you need — the listing does not state how many cams come with the machine, so ask us.
• Whether you need extra masses for the follower, beyond what is quoted.
• Your mains supply, so we can confirm the motor arrangement.

Frequently Asked Questions

What can students investigate with the Cam Analysis Machine?
With the Cam Analysis Machine, students investigate how a follower behaves on a rotating cam as motor speed, follower type, spring preload and follower mass change. The selection of springs, followers and cams allows a wide range of investigations.

Why does the Cam Analysis Machine have a flywheel?
The Cam Analysis Machine SLE/ETM/10 has a substantial flywheel on its main shaft because the torque needed to turn the cam changes during each rotation. The flywheel reduces the resulting speed variations, so test conditions stay steadier.

How many followers and springs are provided?
The Cam Analysis Machine offers a choice of two followers, with a tool for easy changeover, and a choice of two compression springs whose preload can be adjusted. Different masses can also be added to change the follower mass.

How is the cam mounted?
On the Cam Analysis Machine SLE/ETM/10, the cam under test fits to the end of the main shaft and is accurately mounted both axially and radially. This helps ensure repeatable results when cams are changed between experiments.

Acceleration & Static Test Stand (Product Code: SLE/ETM/11) is a separate bench stand used to measure angular acceleration, find inertia by experiment and run static efficiency tests on a gear drive in engineering laboratories. Students use it alongside dynamic gear-drive tests, because a sensor and multiline display calculate the flywheel’s angular acceleration automatically. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Acceleration & Static Test Stand Used For?

Before students can predict how quickly a gearbox speeds up, they need a feel for rotational inertia. On this stand a set of weights applies a known turning force to the flywheel shaft, the sensor follows the flywheel as it speeds up, and the multiline display works out the angular acceleration. From the applied torque and the measured acceleration, the class calculates the flywheel’s inertia and checks it against theory.

Because the flywheel is a simplified version of one of the gears in the gear drive, the experiment is a stepping stone to inertia calculations for complete gear trains. The same stand also runs simple static efficiency tests on the gear drive, giving a second set of figures to set beside dynamic results from the base unit — a useful comparison for moment of inertia and flywheel experiment work in Indian engineering colleges. Keep the weights in the front tray between runs so none go missing.

What to Specify When Ordering

• Whether you already own the gear drive and base unit, or need them quoted with the stand.
• The number of stands, based on how many student groups work at once.
• Your mains supply, so the sensor and display arrangement can be confirmed.

OEM Manufacturer

Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, makes the Acceleration & Static Test Stand as the original equipment manufacturer at its licensed factory at Saha, Ambala, Haryana, India.

Geared Systems (Product Code: SLE/ETM/12) is a bench-mounting base unit used to test the performance and efficiency of gear drives and other drive units under power in engineering laboratories. Students measure power in from a variable-speed, low-voltage motor and power out to an electromagnetic hysteresis dynamometer, and a three-shaft gear drive unit comes as standard. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Geared Systems Base Unit Used For?

Efficiency is the question every drive designer asks: how much of the power put into a gearbox actually reaches the output shaft? In a dynamic test on this base unit, the motor turns the input of the drive unit at a chosen speed while its input power is measured, and the dynamometer brakes the output while the output power is measured. Dividing one by the other gives efficiency, and repeating the run at other speeds and loads builds a full performance picture.

Because the hysteresis dynamometer holds a constant torque regardless of speed, students can change speed without the load drifting. The motor and dynamometer sit in trunnions and push against load cells, so torque readings come from the reaction on the housing. Flexible couplings with collets make it quick to swap the standard three-shaft gear drive for optional drive units, which suits engineering lab equipment for technical institutes that run several groups in one session.

What to Specify When Ordering

• Which optional drive units you want in addition to the standard three-shaft gear drive — ask us what is offered.
• Whether the Acceleration & Static Test Stand should be quoted with the base unit.
• Your mains supply, so the motor and sensor arrangement can be confirmed.
• The number of base units for your laboratory.

OEM Manufacturer

Geared Systems is manufactured by Jain Scientific Equipments Private Limited, trading as ScienceLab, at the company’s own licensed factory at Saha, Ambala, Haryana, India. As the OEM, the company quotes the base unit, the standard gear drive and add-on units together, and handles repeat orders and replacement parts itself — ask us.

Frequently Asked Questions

What does the Geared Systems base unit measure?
The Geared Systems base unit measures shaft speed and torque at both the motor and the dynamometer, and therefore the power into and out of the drive unit. Students use these measurements to find the performance and efficiency of the drive.

How does the dynamometer load the drive?
The dynamometer on Geared Systems SLE/ETM/12 uses electromagnetic braking and a hysteresis effect to provide a variable load at a constant torque, irrespective of speed. It supplies the output braking force while its sensors measure the output power.

Which drive unit comes with Geared Systems?
Geared Systems is supplied with a three-shaft gear drive unit as standard. The base unit can also dynamically test other optional drive units; ask us which ones are available and include them in your quotation request.

How is torque measured accurately?

Free And Forced Vibrations (Product Code: SLE/ETM/13) is a beam vibration apparatus used to study free, forced and damped oscillations in engineering and theory of machines laboratories. Students can set the beam vibrating by hand or force it with a variable-speed servomotor driving a rotating offset mass, while a non-contacting sensor records displacement without adding damping. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Free And Forced Vibrations Apparatus Used For?

Engines, pumps and building floors all vibrate, and engineers need to know the natural frequency of a structure and how strongly it responds when something drives it near that frequency. With this apparatus, a class first plucks the beam by hand to watch free vibration die away, then switches on the exciter and raises the servomotor speed step by step to trace the forced response and find resonance.

Fitting the dashpot and changing its open area adds controlled viscous damping, so students can see how damping lowers the resonant peak. Because the displacement sensor never touches the beam and the pivots run on ball races, very little unwanted damping creeps in. The accelerometer in the exciter shows the phase between displacement and acceleration — a strong SHM and vibration practical for mechanics lab equipment in India.

What to Specify When Ordering

• The computer arrangement for the software — ask us what the software runs on.
• Your mains supply, so the servomotor controller arrangement can be confirmed.
• Whether you need extra dashpot fluid with the order.
• The number of units for your vibration laboratory.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which sells under the ScienceLab name, is the OEM for the Free And Forced Vibrations apparatus and produces it at its own licensed factory at Saha, Ambala, Haryana, India. Engineering colleges and dealers deal with the maker itself for quotations, repeat orders and parts such as the dashpot or sensors — ask us.

All models are listed in the Theory of Machines category.

Frequently Asked Questions

How are vibrations produced on the Free And Forced Vibrations apparatus?
On the Free And Forced Vibrations apparatus, students may vibrate the system manually for free vibration, or force it using a variable-speed servomotor driving a rotating offset mass. The servomotor has its own encoder and controller for accurate speed regulation.

Why is a non-contacting displacement sensor used?
The Free And Forced Vibrations apparatus SLE/ETM/13 measures beam displacement with a non-contacting sensor, so the sensor has no physical contact with the oscillating system. That keeps added damping negligible and the measured response closer to the true behaviour of the beam.

What does the accelerometer show?
The accelerometer built into the exciter assembly of the Free And Forced Vibrations apparatus shows the phase relationship between beam displacement and acceleration. The software also compares measured acceleration with acceleration derived from the displacement readings.

Is damping included?
Yes. The Free And Forced Vibrations apparatus includes a variable-area viscous dashpot damper for use with a non-toxic fluid of stable viscosity, and the fluid is supplied. Changing the damper area lets students compare different levels of damping.

Michell Pad Apparatus (Product Code: SLE/ETM/14) is a bench-mounted, self-contained apparatus used to demonstrate the pressure distribution across the oil film in a Michell tilting pad slider bearing in engineering laboratories. Students read oil pressure on a set of thirteen graduated tubes while adjusting pad tilt and belt speed. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Michell Pad Apparatus Used For?

Large thrust bearings in turbines and ship propeller shafts rely on the tilting pad principle: a slightly inclined pad drags oil into a converging gap, and the wedge of oil builds enough pressure to carry the load without metal-to-metal contact. On this apparatus the moving flat belt plays the part of the runner, the aluminium pad sits above it, and the oil film forms in between, so the whole effect can be seen and measured on a bench.

Students set a tilt with the eccentric shafts, record the leading and trailing edge positions with the micrometers, and read the thirteen tubes to plot pressure under the pad. Changing the belt speed and measuring the oil with the included viscometer then links sliding speed, viscosity and film thickness to pressure distribution — a clear viscosity measurement and lubrication practical for engineering colleges. Keep the oil container closed between sessions so the oil stays clean.

OEM Manufacturer

The Michell Pad Apparatus comes from Jain Scientific Equipments Private Limited, trading as ScienceLab, which manufactures it as the OEM at its own licensed factory at Saha, Ambala, Haryana, India. Laboratories, dealers and importers order it straight from the manufacturer, and questions about oil, tubes or other replacement parts go to the same team — ask us.

Frequently Asked Questions

What does the Michell Pad Apparatus demonstrate?
The Michell Pad Apparatus demonstrates the pressure distribution across the film of oil in a Michell tilting pad slider bearing. Students find how pressure distribution relates to film thickness, sliding speed and oil viscosity.

How is the oil pressure measured?
On the Michell Pad Apparatus SLE/ETM/14, a set of thirteen graduated tubes shows the oil pressure across and along the film under the pad. Readings from all the tubes let students plot the pressure profile for each set-up.

Can the pad angle and belt speed be changed?
Yes. On the Michell Pad Apparatus, two eccentric shafts hold the pad so the angle of tilt can be adjusted, and micrometers measure the leading and trailing edge positions. A variable speed control sets the speed of the motor that turns the belt.

Is oil supplied with the Michell Pad Apparatus?
Yes. A container of oil and a viscometer to measure the viscosity of the oil are included with the Michell Pad Apparatus. For repeat supplies of oil, ask us when you place or plan your order.

Coriolis Force (Product Code: SLE/ETM/15) is a benchtop apparatus used to show the Coriolis force by making a jet of water visibly deflect inside a rotating frame of reference, in physics and engineering laboratories. Students control the arm’s speed and direction of rotation and the pump rate from dials and a digital display on the base unit. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Coriolis Force Apparatus Used For?

The Coriolis effect explains why winds curve across the Earth, why long-range projectiles drift and why fluids behave unexpectedly in rotating machinery, yet it is hard to picture from equations alone. Here the whole reference frame spins: the water tank rides on the rotating arm, the submersible pump fires a jet across it, and anyone watching sees the jet bend away from a straight line as soon as the arm turns.

Students can reverse the direction of rotation and watch the deflection swap sides, raise the speed to see a stronger effect, or change the pump rate to alter the jet velocity. Those three variables make it a memorable physics demonstration kit for dynamics and fluid mechanics lectures. Fill the tank to a sensible level and check that the counterbalance is in place before starting rotation.

OEM Manufacturer

This Coriolis Force apparatus is produced by Jain Scientific Equipments Private Limited, whose trading name is ScienceLab, as the OEM at its own licensed factory at Saha, Ambala, Haryana, India. Universities, colleges and distributors order it factory-direct, so pump, tank or display queries and repeat orders are dealt with by the manufacturer — ask us.

Frequently Asked Questions

What does the Coriolis Force apparatus show?
The Coriolis Force apparatus shows a jet of water deflecting when the arm carrying the water tank rotates. The deflection is due to the Coriolis force, a fictitious force that appears to act on objects moving within a rotating frame of reference.

How is the water jet produced?
In the Coriolis Force apparatus SLE/ETM/15, the transparent water tank on the rotating arm houses a submersible pump that produces the jet of water. The pump rate can be adjusted from the base unit to change the jet.

Which settings can students change?
Dials and a digital display on the Coriolis Force base unit let students adjust the speed of rotation, the direction of rotation and the pump rate. Changing each one shows how the deflection of the jet responds.

Why is there a counterbalance on the arm?
The rotating arm of the Coriolis Force apparatus carries both the transparent water tank and a counterbalance. Balancing the arm helps it rotate smoothly about the benchtop base unit while the demonstration runs.
