At a temperature of 60°F, a 0.04-in. gap exists between the ends of the two bars shown in the figure. Bar (1) is an aluminum alloy (E=10,000 ksi; v= 0.32; a = 12.5 x106/°F] bar with a width of 3 in. and a thickness of 0.75 in. Bar (2) is a stainless steel [E=28,000 ksi; v=0.12; a -9.6 x10-6/°F] bar with a width of 2 in. and a thickness of 0.75 in. The supports at A and C are rigid. Determine the normal stress in bar (1) at a temperature of 450°F (1) 3 in. 32 in. B 2 in. (2) 44 in. 0.04-in. gap

Question
At a temperature of 60°F, a 0.04-in. gap exists between the ends of the two bars shown in the figure. Bar (1) is an aluminum alloy (E-10,000 ksi; u= 0,32; a= 12.5 x10°/°F] bar with a width of 3 in, and a thickness of 0.75 in. Bar (2) is a stainless steel |E-28,000 ksi; u=0.12; a=9.6x10°/°F] bar with a width of 2 in. and a thickness of 0.75 in. The supports at A and C are rigid. Determine the normal stress in bar (1) at a temperature of 450°F
