A shaft made of aluminum is 21 mm in diameter at a temperature of 21^oC. The coefficient of thermal expansion for aluminum is given in Table 4.1. If it must be reduced in size by 0.06 mm in order to be expansion-fitted into a hole, determine the temperature to which the shaft must be cooled (in ^oC).
