The results below were obtained from a tension test. the test specimen had a diameter of 0.505 in. and a gage length of 2.00 in. at fracture, the elongation between the gage marks was 0.12 in and the minimum diameter was 0.42 in. plot the stress-strain curve and determine: the proportional limit modulus of elasticity yield stress at 0.2% offset ultimate stress percent elongation and percent area reduction. identify the material being tested (see average material properties in the back of your textbook). an identical sample is loaded to an elongation of 0.020 in. and then unloaded. how does the final length of the bar compare with its original length?
