The data shown in the table were obtained from a tensile test of high-strength steel. The test specimen had a diameter of 13 mm, and a gage length of 50 mm was used. The total elongation between the gage marks at fracture was 10.7 mm, and the minimum diameter was 9.4 mm. Plot the nominal stress-strain diagram for the steel and determine the proportional limit, modulus of elasticity, yield stress at 0.1 % offset, ultimate stress, percent elongation in 50 mm, and percent reduction in area.
