An aluminum rod (E = 70 GPa, α =23.6 x 10-6/°C) and steel link (E = 200 GPa, α = 11.7 x 10-6/°C) have the dimensions shown at a temperature of 20oC. The steel link is heated until the aluminum rod can befitted freely into it. The temperature of the whole assembly is then raised to 150°C. Determine the final stress in the rod and in the link.
