Question: 1. Compute the modulus of elasticity of a copper alloy wire that stretches 14.0 mm when subjected to a load of 320 N. The wire is 4.00 m long and has a diameter of 1.00 mm.
2. A concrete cylinder 6 in. in diameter was tested in compression and observed to have shortened by an amount of 0.0029 in. over a gage length of 12 in. Total load at the time of the reading was 20,000 lb. Compute the modulus of elasticity, E.
