1. Derive an expression for the couple per angular twist for a solid wire having a radius 'r'
and length 'l' which is under torsions.
2. Bring out experimental verification of Young's modulus of a beam by Non uniform bending. Also, plot the stress-strain graph for the following data and determine the mass 'x' of unknown object from graph:

2. Bring out experimental verification of Young's modulus of a beam by Non uniform bending. Also, plot the stress-strain graph for the following data and determine the mass 'x' of unknown object from graph:
| Load x 10-3 Kg | X axis | 50 | 100 | 150 | 200 | x |
| Depression 10-2 m | Y axis | 0.13 | 0.26 | 0.52 | 1.03 | 2.25 |
