Part 1 At a temperature of 60°F, a 0.05-in. gap exists between the ends of the two bars shown. Bar (1) is an aluminum alloy [E = 10,000 ksi; v = 0.32; a = 12.5 x 106/°F] bar with a width of 2.7 in. and a thickness of 0.65 in. Bar (2) is a stainless steel [E = 28,000 ksi; v = 0.12; a = 9.6 x 106/°F] bar with a width of 1.6 in. and a thickness of 0.65 in. The supports at A and C are rigid. Assume h₁=2.7 in., h₂=1.6 in., L₁=26 in., L2=40 in., and 4 = 0.05 in. Determine (a) the lowest temperature at which the two bars contact each other. (b) the normal stress in the two bars at a temperature of 225°F. (c) the normal strain in the two bars at 225°F. (d) the change in width of the aluminum bar at a temperature of 225°F.
