Question: In an experiment in the testing laboratory, a specimen 20 mm in diameter and 250 mm long reached the elastic limit under a tensile load of 120 kN and failed under a load of 175 kN. The length of the bar at its elastic limit was 251.2 mm, and at failure was 333.8 mm. Compute the stress at the elastic limit, the ultimate tensile stress, and the strain for the elastic limit.
