Steel Aluminum A = 2 in.2 E = 10 x 106 psi A = 3 in.2 E = 29 x 10° psi 50 kips 15 in.- 10 in.- FIG. P2.86, P2.87

2.86 The composite bar is firmly attached to unyielding supports. The bar is stress-free at 60°F. Compute the stress in each material after the 50-kip force is ap- plied and the temperature is increased to 120°F. Use a = 6.5 × 10-6/ºF for steel and a = 12.8 x 10-6/°F for aluminum.
