Calculate the change in length of the aluminum rod

Reference no: EM13322707

A straight rod consists of a 2cm long piece of aluminum attached to a 3cm long piece of steel. The temperature of the rod increases from 20 C to 40 C. The coefficient of linear expansion for aluminum is 23x10^-6 K and for steel is 12x10 ^-6 K.

A) calculate the change in length of the aluminum rod?

B) calculate the change in length of the steel rod?

C) by how much with the length of the entire rod increase?
