A straight rod consists of of 0.82 cm long piece of aluminum attached to a 2.84 cm long piece of steel. By how much will the length of this rod change if its temperature is increased from 11 degree celsiu to 28 degree celsius. The average coefficient of linear expansion of aluminum and steel is 2.5x10^-5 (celsius)^-1 and 1.2 x10^-5 (celsius)^-1 respectively.

You want to insert an aluminum rod, which at 20°C has a radius of 1.00020 cm into a copper tube which has a radius of 1.00010 cm at the same temperature. You decide to put both of them in the refrigerator. At what temperature will the rod just fit if both are cooled to the same temperature? The coefficient of thermal expansion for aluminum is 2.4 × 10-5 K-1, and that of copper is 1.7 × 10-5 K-1.
