Assignment

1. Determine the value of Young's modulus of the given wooden bar having breadth 1 cm and thickness 0.4 cm. Fix the distance between knife edges at 25 cm and the distance between weight hangers at 35 cm. Choose Earth as the environment and perform the whole experiment in the uniform bending arrangement.
2. Perform the uniform bending experiment by selecting the material as steel, and set the breadth and thickness of the material to 2 cm and 0.3 cm. Calculate the Young's modulus of steel on Earth by fixing the distance between knife edges at 35 cm and the distance between weight hangers at 45 cm.
3. Calculate the value of l²/e by uniform bending on Earth for an aluminum bar with dimensions 1 × 0.2 cm and a 250 g load, when the minimum distance is adjusted for knife edges and weight hangers from the pin in the simulator.
4. Determine the value of Young's modulus of the given steel bar having breadth 1 cm and thickness 0.45 cm. Fix the distance between knife edges at 40 cm and the distance between weight hangers at 60 cm. Choose Earth as the environment and perform the whole experiment in the uniform bending arrangement.
5. Measure the elevation produced by the copper bar with a 300 g load by uniform bending when the distance between the weight hangers is 50 cm and the knife edges is 25 cm. The bar has a breadth of 1.5 cm and thickness of 0.2 cm. Perform the experiment on the Moon.
