A steel [E = 200 GPа; ν = 0.3; α = 11.4 ×10-6/°C] plаte hаs a rectangular hоle at its center and fоur circular hоles at the corners. At an initial temperature of Ti = –12°C, the plate is 90 mm wide, 125 mm long, and 18 mm thick. The rectangular hole is 25 mm wide and 75 mm long. The circular holes have a diameter of 19 mm. At a final temperature of Tf = 45°C, determine the length of the rectangular hole.
