A Solid steel shaft running at 600rpm is supported on bearings 600mm apart. The shaft receives 40kW through a 400mm diameter pulley weighing 400N located 300mm to the right of left bearing by a vertical flat belt drive. The power is transmitted from the shaft through another pulley of diameter 600mm weighing 600N located 200mm to the right of right bearing. The belt drives are at right angles to each other and ratio of belt tensions is 3. Determine the size of the shaft necessary, if the allowable shear stress in the shaft material is 40MPa and the loads are steady.

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
