Find the change in the length of the beam due to cooling

Reference no: EM13486992

A beam used in construction is made of steel, which has a coefficient of linear expansion of 1.3 × 10-5 K-1. The beam is 31 m long at a temperature of 1636 K when it is made. As it cools, the temperature of the beam decreases to 301 K.

1) What is the change in the length of the beam due to cooling?

2) If the mass of the steel beam is 403 kg and the specific heat capacity of steel is 490 J/kg-K, how much energy did the steel beam lose due to cooling? (Use a positive value for the amount of energy.)
