2. A cast-iron gear with 100 mm effective diameter and t = 40 mm hub engagement length is to transmit a maximum torque of 120 N·m at low speeds. Determine (a) the required radial interference, in millimeters, on a 20-mm diameter steel shaft, (b) the maximum stress in the gear due to a press fit and (c) the speed, in RPM, at which the press fit loosens. Given: E = 100 GPa, Es = 200 GPa, v = 0.3, f = 0.16 and the density of the cast iron pe = 7.2 kN-s?/m* (Note: This problem is an exact copy of problem 8.39 from the textbook with part (c) added)
