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 elasticity. the yield stress, the ultimate stress., and the fracture stress. Use a scale of I in. = 20 ksi and 1 in. = 0.05 in.fin. Redraw the elastic region. using the same stress scale but a strain scale of l in.= 0.001 in.fin.
