The strength coefficient and strain hardening exponent of a certain test metal are 40,000 lb/in2 and 0.19, respectively. A cylindrical specimen of the metal with starting diameter = 25 in and length = 3.0 in is compressed to a length of 1.5 in. Determine the flow stress at this compressed length and the aver-age flow stress that the metal has experienced during deformation.
