Assignment

1. Calculate the value of Young's modulus of a copper bar by non-uniform bending. The length and thickness of the bar are 1 cm and 0.2 cm respectively. Fix the distance between knife edges at 25 cm. Perform the whole experiment on the Moon.
2. Draw a graph connecting the distance between knife edges and depression, and calculate the value of Young's modulus of a copper bar by non-uniform bending. The length and thickness of the bar are 2 cm and 0.3 cm respectively. Fix the distance between knife edges at 30 cm. Perform the whole experiment on Uranus.
3. Determine the value of Young's modulus of a given wooden bar having breadth 3 cm and thickness 0.5 cm. Fix the distance between knife edges at 30 cm. Choose Earth as the environment and perform the whole experiment in the non-uniform bending arrangement.
4. Calculate the value of Young's modulus of an aluminum bar by non-uniform bending. The length and thickness of the bar are 1 cm and 0.2 cm respectively. Fix the distance between knife edges at 50 cm. Perform the whole experiment on Saturn.
5. Determine the value of Young's modulus of a given steel bar having breadth 3 cm and thickness 0.45 cm. Fix the distance between knife edges at 40 cm. Choose Earth as the environment and perform the whole experiment in the non-uniform bending arrangement.
