Question

Steel Beam A beam used in construction is made of steel, which has a coefficient of linear expansion of 1.3 x 105 K1. The beam is 30 m long at a temperature of 1635 K when it is made. As it cools, the temperature of the beam decreases to 300 K 1) What is the change in the length of the beam due to cooling? m Submit 2) If the mass of the steel beam is 390 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.) J Submit
