A brass link (Eb=105 GPa, αb=20.9 3 10–6/°C) and a steel rod (Es= 200 GPa, αs=11.7 3 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
