Question

A shaft is supported by two bearings placed 2m apart. A 700m diameter pulley is mounted at a distance of 300mm to right of left hand bearing and this drives a pulley directly below it with the help of belt having maximum tension 3kN. Another pulley 300mm diameter is placed 200mm to the left of right hand bearing is driven with the help of electric motor and belt, which is place horizontally to the right . The angle of contact for both the pulley is 120 degrees and u=0.24. Determined the suitable diameter for a solid shaft, allowing working stress of 60MPa in tension and 40MPa in shear for the material of shaft. Assume that the torque on one pulley is equal to that on 40MPa in shear for the material of shaft. Assume that the torque on one pulley is equal to that on the other pulley
