A brass link (E_b = 105 GPa, α_b = 20.9 × 10^–6/°C) and a steel rod (E_s = 200 GPa, α_s = 11.7 × 10^–6/°C) have the dimensions shown at a temperature of 20°C. The steel rod is cooled until it fits freely into the link. The temperature of the whole assembly is then raised to 45°C. Determine (a) the final normal stress in the steel rod, (b) the final length of the steel rod.
