Assignment

1. Calculate the rigidity modulus of copper having radius 3 mm fixed on a pulley with radius 5 cm. The whole experiment is carried out by choosing Earth as the environment.
2. An aluminum rod having radius 4 mm is fixed on a pulley with radius 6 cm. Calculate the rigidity modulus of the material using the simulator. Choose Saturn as the environment.
3. Calculate the rigidity modulus of brass having radius 3.5 mm fixed on a pulley with radius 5.5 cm. The whole experiment is carried out in Jupiter.
4. What happens to the value of rigidity modulus when the radius of the copper rod is increased from 4 mm to 5 mm? The radius of the pulley is 7 cm and the experiment is to be performed on the Moon.
5. An iron rod having radius 4 mm is fixed on a pulley with radius 6 cm. Calculate the rigidity modulus of the material using the simulator. Choose Uranus as the environment.
