QI/ The power transmitted by the motor to the main shaft as shown in figure (1) are 15 kW with the rpm of the motor is 600. The diameter of the machine pulley C is 180 mm. The ratio of the tight- and slack- tensions on the belt is 3. Two bearings A and B support the shaft. The shaft made from carbon steel with SAE number 1040 cold rolled. Determine the shaft diameter if the torque applied is dynamically reversed and the bending moment is applied statically. The pulley and gear are mounted on shaft using keyways. Design these keys if the key material is the same of the shaft material. Fig. (1)
