A bronze ring of 16 in. outside diameter is shrunk around a steel shaft of 8 in. diameter. At room temperature the shrink allowance is 0.001 in./in/ (that is 0.004 in. on the radius). Calculate:

a) The temperature above room temperature to which the entire assembly must be raised in order to loosen the shrink fit.
