Force Board, Wall Type (Product Code: SLE/PHY/174) is a wall-mounted board used to demonstrate the parallelogram and polygon of forces in school and college mechanics lessons. Measuring 750 x 600 mm, it leaves a clear space all round the edge for attaching pulleys, and it comes complete with mounting brackets, cords, pulleys and masses. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

Specifications

What Is the Wall Force Board Used For?

Pulleys attached at the board's edge carry cords to a common knot, with masses hanging from each cord. When the knot comes to rest, students trace the cord directions on a sheet of paper fixed to the board, draw the forces to scale and check that they close into a triangle or polygon — the heart of vector addition in mechanics lab equipment for Indian schools and colleges.

Because the board hangs on the wall, a whole class can watch the same demonstration without crowding round a bench, and the teacher can leave it set up between lessons. Fix the brackets into a solid wall, check the board is vertical, and let the knot settle fully before recording any angles.

Force Table (Product Code: SLE/PHY/175) is a circular vector-addition apparatus used to balance three or four forces and verify equilibrium in school and college physics labs. It has a 40 cm diameter polymer tabletop with an angle scale in 0.5° divisions, a heavy cast base with levelling screws, and four clamp pulleys with slotted masses. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

Specifications

What Is the Force Table Used For?

Students hang known masses over two or three pulleys, work out the resultant by scale drawing or by components, then set the last pulley at the predicted angle with the balancing mass. If the prediction is right, the point where the cords meet settles over the centre of the table — vector addition made tangible. The split rings let groups switch between three-force and four-force equilibrium in moments, which suits any basic physics lab.

Level the tabletop with the spirit level and the base's levelling screws before each session so the masses pull horizontally across the scale. Line each cord up with the fiducial mark on its pulley to read angles to the nearest scale division. It is a standard item of mechanics lab equipment in India for vector topics in senior secondary and first-year college practicals.

Forced Oscillation and Resonance Demo (Product Code: SLE/PHY/176) is a motor-driven demonstrator used to show how an object vibrates under repeated impulses and when resonance occurs, in secondary and college physics classes. Two cams driven by a 6 V motor with speed control act on two weights of different natural frequencies, working together with four springs. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Forced Oscillation and Resonance Demo Used For?

Start the motor slowly and raise the speed: at first both weights move only slightly, then one begins to vibrate strongly as the driving frequency matches its natural frequency while the other stays fairly calm. Increase the speed further and the second weight takes its turn. Resonance, and its dependence on natural frequency, becomes visible in a way equations alone cannot show, supporting the forced-vibration part of any SHM experiment kit used in Indian syllabi.

Because the speed control allows a wide range of driving frequencies, students can locate each resonance and discuss real examples such as swaying bridges and vibrating machines. Connect a suitable 6 V source, begin at low speed, and read the included manual before the first run.

What to Specify When Ordering

• A 6 V power source, since none is included with the demonstrator.
• The number of units for your physics department.
• Whether you would like other oscillation or resonance apparatus quoted in the same order.

Friction Cloth, Cotton (Product Code: SLE/PHY/177) is a square cotton rubbing cloth used to charge friction rods in static electricity experiments in school physics labs. Each 300 x 300 mm cloth gives enough area to grip a rod and rub it firmly along its length before bringing it near an electroscope or pith ball. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as an accessory for electrostatics work.

Specifications

What Is the Cotton Friction Cloth Used For?

Rubbing a rod with the cloth transfers electrons between the two surfaces, leaving the rod charged and ready to deflect an electroscope, lift small scraps of paper or swing a pith ball. Using the same cotton cloth with rods of different materials lets students compare which pairings charge most strongly, so it earns a place in the consumables drawer of any school physics lab in India.

Keep cloths dry and clean, because moisture or grease reduces charging. Store them in a closed bag between lessons, and give each student group its own cloth so that rubbing conditions stay consistent across the class.

Friction Rod, Brass/Ebonite (Product Code: SLE/PHY/178) is a charging rod used for various experiments involving static electricity in school and college physics labs. Listed in brass/ebonite and measuring 300 x 12 mm, it is rubbed with a cloth to build up charge that can then be passed to an electroscope or used to attract light objects. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Brass/Ebonite Friction Rod Used For?

Ebonite, a hard rubber, is a traditional material for static demonstrations because it charges readily when rubbed, while brass is a conductor. Having both materials lets teachers discuss why an insulator holds charge where it was rubbed, whereas a conductor held in the hand loses its charge to earth — a key idea in school physics lab equipment courses across India.

Rub the rod briskly with a dry cloth, then bring it near an electroscope plate or a suspended pith ball. Wipe the rod after handling, since skin oils and moisture reduce charging, and store it somewhere dry. If your experiment depends on how the brass and ebonite portions are arranged, confirm this with us when you request a quotation.
