The composite bar shown in Fig. P-273 is firmly attached to unyielding supports. An axial force P = 50 kips is applied at 60°F. Compute the stress in each material at 120°F. Assume a = 6.5 x 10 6 in/(in-°F) for steel and 12.8 x 10-6 in/(in-°F) for aluminum. Steel A = 3 in? E = 29 x 10° psi Aluminum A = 2 in? E = 10 x 10° psi 15 in 10 in
