A steel [E = 200 GPa; ν = 0.3; α = 11.5 ×10-6/°C] plate has a rectangular hole at its center and four circular holes at the corners. At an initial temperature of Ti = –13°C, the plate is 85 mm wide, 125 mm long, and 12 mm thick. The rectangular hole is 35 mm wide and 70 mm long. The circular holes have a diameter of 16 mm. At a final temperature of Tf = 50°C, determine the width of the plate.
