Cantilever Apparatus
Product Code : EL-AM-10323
Quick answer: The Cantilever Apparatus is a chrome-plated steel bar marked with lines every 5 cm and fitted with a hook at one end. Clamped horizontally with its breadth flat, it is loaded at the free end to measure depression and find Young's modulus of steel, and to show how depression grows with the loaded length. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the cantilever experiment is done
A cantilever is a beam fixed at one end and loaded at the other. For a load W at a distance L from the clamp, a rectangular bar of breadth b and thickness d is depressed by delta = 4 W L^3 / (Y b d^3), where Y is Young's modulus. Because the depression depends on the cube of the length, the lines every 5 cm let students set exact lengths and test the L^3 relation as well as measure Y.
- Clamp the end without the hook firmly to the bench edge, with the breadth of the bar horizontal.
- Set a vertical scale or travelling microscope at the hook end and note the reading with no load.
- Hang masses from the hook in equal steps and record the depression for each load, then unload and read again.
- Repeat with the bar clamped at different marked lines to change the loaded length L.
- Plot depression against load, and against L^3, and calculate Y from the slope.
