A steel pulley with a minimum room-temperature bore diameter of 100.00 mm is to be shrunk onto a steel shaft with a maximum room-temperature diameter of 100.15 mm. Assume the following: Room temperature = 20°C Coefficient of linear expansion of steel = 11 x 10-6°C Required diametral clearance for assembly = 0.05 mm To shrink the pulley onto the room-temperature shaft with the desired diametral clearance, the pulley must be heated to a minimum temperature of most nearly:
