In a compression test, a steel test specimen (modulus of elasticity = 30 x 106 lb/in2) has a starting height = 2.0 in and diameter = 1.5 in. the metal yields (0.2% offset) at a load = 140,000 lb. at a load of 260,000 lb, the height has been reduced to 1.6 in. determine (a) yield strength and (b) flow curve parameters (strength coefficient and strain-hardening exponent). assume that the cross sectional area increases uniformly during the test.
