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 steel specimen having a modulus of elasticity equal to 29x103ksi has a width of 1.0in and thickness of 0.25in. During the tensile strength testing, the specimen yielded at 12.5kips and fractured at 17.5 kips. Compute the value of the tensile stresses at yield and fracture
