A steel [E = 200 GPа; ν = 0.3; α = 11.2 ×10-6/°C] plаte hаs a rectangular hоle at its center and fоur circular hоles at the corners. At an initial temperature of Ti = –11°C, the plate is 90 mm wide, 115 mm long, and 11 mm thick. The rectangular hole is 35 mm wide and 65 mm long. The circular holes have a diameter of 18 mm. At a final temperature of Tf = 41°C, determine the length of the plate.
