Below question is from machine design. Please solve asap. You have to select bearings which are used to support a shaft, bearings are mounted at each end of shaft and 1.20 metre apart. A 600 mm diameter pulley is mounted at a distance of 300 mm to the right of left hand bearing and this drives a pulley directly below it with the help of belt having maximum tension of 2.25 kN. Another pulley 400 mm diameter is placed 200 mm to the left of right hand bearing and is driven with the help of electric motor and belt, which is placed horizontally to the right. The angle of contact for both pulleys is 180º and .Allowing working stress of shaft depends on the material you have selected for the shaft. Select the type of bearing mounted on both ends of shaft (either ball or roller bearing type and also elaborate the scenario for the selection of bearing).The Reliability Factor for Bearing may vary from 92% till 96%
