A 150 kg steel rod in a building under construction supports a load of 6050 kg. During the day, the rod’s temperature increases from 22°C to 47°C. This temperature increase causes the rod to thermally expand and raise the load 5.5 mm.
a. Find the energy transferred as heat to or from the rod. (Hint: Assume the specific heat capacity of steel is the same as for iron.)
b. Find the work done in this process. Is work done on or by the rod?
c. How great is the change in the rod’s internal energy? Does the rod’s internal energy increase or decrease?
