An open belt system is transmitting 10 kW power . Driving pulley is of diameter 200mm and driven pulley is of diameter 480 mm. Centre distance between the pulleys is 2 m. Maximum stress in belt is not to exceed 2.2 MPa. Thickness of the belt is 8 mm . Determine breadth and length of the belt.

Given density of belt material = 950 kg/m3, Coefficient of friction between belt and pulley = 0.3, Driving pulley is rotating at 1000 rpm. Neglect bending stress in belt.
