In the pulley system shown in Figure Q1 the tangential forces on the pulleys are shown. Each pulley adds an additional load / weight of 500N on the shaft. Calculate a suitable shaft diameter so that to avoid failure by the maximum shear stress criterion. The tensile yield strength of the shaft material is 248MN/m2 . The shaft weight may be neglected and the shaft bearings may be treated as simple supports.
