The following stress and strain values were measured in the plastic region during a tensile test carried out on a new experimental metal: (1) true stress = 43,608 lb/in2 and true strain = 0.27 in/in, and (2) true stress = 52,048 lb/in2 and true strain = 0.85 in/in. Based on these data points, determine the strength coefficient and strain-hardening exponent.
