bar of aluminum fits

A solid circular bar of aluminum fits inside a tube of copper having the same length (see figure). The outside diameter of the copper tube is 50 mm, the inside diameter is 45 mm, and the diameter of the aluminum bar is 44 mm. At each end of the assembly, a metal pin of 6 mm diameter goes through both bars at right angles to the axis. Find the average shear stress in the pins if the temperature is raised 17°C. (For aluminum, Ea = 70 GPa and αa = 23 X 10-6/°C; for copper, Ee = 117 GPa and αc = 16.6 X 10-6/°C)
