A solid shaft of 1020 steel with an outside radius of 1.002 cm is to be inserted inside a hollow 1020 steel shaft with an inside radius of 1.000 cm. This is to be accomplished by heating the hollow shaft sufficiently so that the solid shaft can be inserted into the hollow shaft with a radial clearance of 0.002 cm. When the two shafts are brought to room temperature, they will be bonded together as a single unit. This process is called a shrink fit. To what temperature must the hollow shaft be heated for this process, assuming that the solid shaft is at 300 K?
