A tensile test of a metal was run in the laboratory, but only the maximunm load was measured during the test (max load = 59 kN). All other data were taken before and after the test as follows: Initial diameter: Minimum diameter after test (at point of fracture): Maximum diameter after test (away from fracture): 13.0mm 10.0mm 11.6mm Calculate: a. The strain hardening exponent, n, in the power relation = He". b. The load on the specimen at the instant just prior to fracture, P.
