Example The preliminary design of a large shaft connecting a motor to a generator calls for the use of a hollow shaft with inner and outer diameter of 100 mm and 150 mm respectively. Knowing that the allowab shearing stress is 84MPa. Determine the maximum torque that can be transmitted (a) by the shaft as designed, (b) by a solid shaft of the same weight, (c) by a hollow shaft of the same weight and 200 mm outer diameter. D) 4 100 mm 150 mm 2.4 m
