A cable is made of two strands of different materials, A and B, and cross sections as follows: For material A, K = 60, 000 psi, n = 0.6, Ao = 0.6 in2 For material B, K = 30, 000 psi, n = 0.5, Ao = 0.3 in2 Calculate the maximum tensile force that this cable can withstand prior to necking on strand A and B (Non of the strands A or B should pass their necking region).
