A steel specimen is tested in tension. The specimen is 2 in. wide by 2.3 in. thick in the test region. By monitoring the load dial of the testing machine, it was found that the specimen yielded at a load of 30 kips and fractured at 40 kips. a) Determine the tensile stress at yield and fracture; b) If the original gauge length was 4 in., estimate the gauge length when the specimen is stressed to 2 the yield stress.

A tension test is being conducted on a steel-rod specimen with a gauge length of L0=2 in and initial diameter of d0=0.5 in. Data were collected to form the conventional stress-strain diagram as shown. From the diagram, f = 74.0 ksi, e = 104.0 ksi , g = 85.0 ksi , and h = 0.15 in/in. Assuming that the strain remains constant throughout the region between the gauge points, determine the nominal strain ε experienced by the rod if it is elongated to L = 2.7 in . Assuming that the stress is constant over the cross-sectional area and if the tension force used is P = 11.0 kips, find the nominal stress experienced by the rod. Determine the force P needed to reach the ultimate stress in the steel-rod specimen.
