Unsymmetrical Cantilever
Unsymmetrical Cantilever (Product Code: SLE/ETP/15) is a frame-mounted structures apparatus used to load a cantilever and measure its deflection in any coplanar direction, so students can study bending of unsymmetrical sections in strength-of-materials labs. The test beam hangs vertically from a holding ring that rotates through 360 degrees, and a cross-piece at the free end locates the shear centre. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of lab equipment for technical institutes, at its own factory in Ambala, India.
Key Details

What Is the Unsymmetrical Cantilever Used For?
Angles, channels and other sections without two axes of symmetry do not simply bend in the direction they are pushed. A load that is not aligned with a principal axis also makes the beam deflect sideways, and a load that misses the shear centre makes it twist as well. The Unsymmetrical Cantilever turns these abstract ideas from the textbook into measurements students can see.
Students apply loads in set increments, record the displacement, then rotate the beam on its holding ring and repeat. Plotting the results and using Mohr's circle gives the principal second moments of area of each section. For the shear centre, a cross-piece on the free end lets loads be moved across and outside the section until the twisting disappears. Take readings on loading and unloading, and keep loads within the elastic range of the beam.
OEM Manufacturer
Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of the Unsymmetrical Cantilever and makes it at its own licensed factory at Saha, Ambala, Haryana. The company is a registered MSME with manufacturing as its major activity (Udyam UDYAM-HR-01-0003714), and export orders are shipped under Importer-Exporter Code AAECJ8618A (DGFT). Engineering colleges, dealers and importers buy directly from the maker; see the company profile.

- Stiffness - Bending and Torsion — bending stiffness of beams of different materials and cross-sections.
- Torsion of Circular Sections — measures torque and twist, useful before studying twisting about the shear centre.
- Hangers with Slotted Weights — convenient masses for applying loads in equal increments.
- Strain Gauge Trainer — adds strain measurement in bending, torsion and tension.

Frequently Asked Questions
What does the Unsymmetrical Cantilever demonstrate?
The Unsymmetrical Cantilever demonstrates how beams of unsymmetrical section deflect under load in directions other than the load line. Students measure deflection in any coplanar direction and find principal second moments of area and the shear centre.
How is the beam orientation changed on the Unsymmetrical Cantilever?
On the Unsymmetrical Cantilever, the upper end of the vertical test beam fixes to a holding ring that can rotate through 360 degrees. Students rotate the beam to a new position and repeat the loading to build a full picture.
How do students find the shear centre with the Unsymmetrical Cantilever?
To find the shear centre with the Unsymmetrical Cantilever, students attach a cross-piece to the free end of the test beam. It allows loads to be applied at different positions across and outside the section while twisting is observed.
How are the principal second moments of area found?
With the Unsymmetrical Cantilever, students apply loads in set increments, record the displacements and then use the Mohr's circle method on the results to find the principal second moments of area of each beam section.
Who manufactures the Unsymmetrical Cantilever?
The Unsymmetrical Cantilever is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory in Ambala, Haryana, India. Enquiries about test beams and spare parts go directly to the manufacturer.
What should a quotation request for the Unsymmetrical Cantilever state?
A quotation request for the Unsymmetrical Cantilever should state the product code SLE/ETP/15, the number of units, which beam sections you want to test and the delivery destination, so we can confirm what the quotation covers.
