1. During a stress-strain test, the unit deformation at a stress of 5,000 psi was observed to be 0.000167 in./in. and at a stress of 20,000 psi it was 0.000667 in./in. If the proportional limit is 30,000 psi, what is the modulus of elasticity? What is the stress corresponding to a strain of 0.0002 in./in.? Would these results be valid if the proportional limit were 18,000 psi? Explain. 2. A steel wire 30 feet long, hanging vertically, supports...
