A compression test is performed on a 2” diameter by 5” long bar of an unknown metal. At the end of the compression test, the bar has a height of 3.5 inches. The strength coefficient (K) and the work hardening coefficient (n ) are 250 MPa and 0.4, respectively. State all assumptions needed to work the problem. a) Calculate the final diameter of the bar in inches. b) Calculate the flow stress in MPa when the length of the bar is 4
