An overhang shaft carry a 900mm diameter pulley, whose center is 250mm from the center of nearest bearing. The weight of the pulley is 600N and the angle of lap is 180°.The pulley is driven by motor horizontally to right it, if the permissible tension in the belt is 2650N and the coefficient of friction between the belt and the pulley surface is 0.3, estimate the diameter of the shaft. Note, Neglect centrifugal tension and assume permissible tensile and shear stresses in the shaft as 84MPA and 68MPa respectively.
