Sample ME8593 Important 8 Mark Questions DESIGN OF MACHINE ELEMENTS:
A mild steel shaft transmits 20kW at 200 rpm. It carries a central load of 900N and is simply supported between the bearings 2.5m apart. Determine the size of the shaft, if the allowable shear stress is 42 MPa and the maximum tensile or compressive stress is not to exceed 56MPa.What size of the shaft will be required, if it is subjected to gradually applied loads?

A transmission shaft supporting a helical gear B and an overhang bevel gear D is shown in fig. The shaft is mounted on two bearings A and C. The pitch circle diameter of the helical gear is 450 mm and the diameter of the bevel gear at the force is 450mm. Power is transmitted from the helical gear to the bevel gear. The gears are keyed to the shaft. The material of the shaft is steel 45C8 (Sut =600 and Syt = 380 N/mm2). The factors Kb and Kt of ASME code are 2.0 and 1.5 respectively. Determine the shaft diameter using the ASME code. ME8593 Important 8 Mark Questions
A shaft is supported on bearing A and B, 800 mm between centers. A 20˚ straight tooth spur gear having 600mm pitch diameter, is located 200 mm to the right of the left had bearing A, and a 700 mm diameter pulley is mounted 250 mm towards the left of bearing B. The gear is driven by a pinion with a downward tangential force while the pulley drives a horizontal belt having 180˚ angle of wrap. The pulley also serves as a flywheel and weights 2000N. The maximum belt tension is 3000 N and the tension ratio is 3:1. Determine the maximum bending moment and the necessary shaft diameter if the allowable shear stress of the material is 40 MPa.
