### Sample ME8593 Question Bank DESIGN OF MACHINE ELEMENTS:

A steel solid shaft transmitting 15kW at 200 rpm is supported on two bearing 750 mm apart and has two gears keyed to it. The pinion having 30 teeth of 5mm module is located 100 mm to the left of the right hand bearing and delivers power horizontally to the right. The gear having 100 teeth of 5mm module is located 150mm to the right of the left hand bearing and receives the power in vertical direction below. Using an allowable stress of 54MPa in shear, determine the diameter of the shaft. ME8593 Question Bank Design Of Machine Elements

A hollow shaft of 0.5m outside diameter and 0.3m inside diameter is used to drive a propeller of a marine vessel. The shaft is mounted on bearings 6m apart and it transmits 5600kW at 150 rpm. The maximum axial propeller shaft is 500kN and the shaft weighs 70kN.Determine ME8593 Question Bank Design Of Machine Elements
(i).The maximum shear stress developed in the shaft
(ii).The angular twist between the bearings. (13)

A section of commercial shafting 2m long between bearings carries a 1000N pulley at its midpoint as shown in fig. The pulley is keyed to the shaft and receives 30 KW at 150 rev/min which is transmitted to a flexible coupling just outside the right bearing. the belt drive is horizontal and some of the belt tensions is 8000 N. Assume Kt = Kb = 1.5. Calculate the necessary shaft diameter and determine the angle of twist between bearings. G=80 GN/m2. ME8593 Question Bank Design Of Machine Elements
