A steel [E = 200 GPa; ν = 0.3; α = 10.9 ×10-6/°C] plate has a rectangular hole at its center and four circular holes at the corners. At an initial temperature of Ti = –10°C, the plate is 95 mm wide, 135 mm long, and 11 mm thick. The rectangular hole is 30 mm wide and 65 mm long. The circular holes have a diameter of 17 mm. At a final temperature of Tf = 43°C, determine the width of the rectangular hole.

Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 2,829 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 10 in., b = 16 in., c = 32 in., and d = 10 in. Assume there is no slack in the connections.
