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. Figure P-273 and P-274 Aluminum A = 2 in? E = 10 x 10° psi Steel A = 3 in? E = 29 x 10° psi 15 in 10 in

Follow-up Question
I just have one question to clarify. The given problem stated that in the part of value of Eal=10×10(race to -6) psi and the given we have in the problem for the value of Est=10×10(race to -6). Why is that on the solving part in yoir solution you are using 10×10(race to 6) instead of 10×10(race to -6)? I'm just curious, how did it happen? Did the value will still be the same? Can you give me the reason? Thank you!
