A tension test was performed on a steel specimen having an original diameter of 0.503 in. and gage length of 2.00 in. The data is listed in the table. Plot the stress-strain diagram and determine approximately the modulus of clasticity, the yield stress, the ultimate stress, and the fracture stress. Use a scale of 1 in. $=20$ ksi and 1 in. $=0.05$ in. $/$ in. Redraw the elastic region, using the same stress scale but a strain scale of 1 in. $=0.001$ in. $/$ in.

The stress-strain diagram for a steel alloy having an original diameter of 0.5 in. and a gage length of 2 in. is given in the figure. If the specimen is loaded until it is stressed to 70 ksi, determine the approximate amount of elastic recovery and the increase in the gage length after it is unloaded.
