A steel [E = 200 GPa; ν = 0.3; α = 10.8 ×10-6/°C] plate has a rectangular hole at its center and four circular holes at the corners. At an initial temperature of Ti = –14°C, the plate is 90 mm wide, 150 mm long, and 20 mm thick. The rectangular hole is 30 mm wide and 75 mm long. The circular holes have a diameter of 21 mm. At a final temperature of Tf = 46°C, determine the width of the plate.

An upward load is applied to a circular rod that has a diameter of 10.51 mm. The rod is connected to the ground using a pin that has a diameter of 9.91 mm. If the average shear stress in the pin is limited to 180 MPa, determine the maximum load that can be applied to this connection.
