A fan is driven by a belt from a motor which runs at 880 rpm. A medium double ply leather belt 8 mm thick and 250 mm wide is used. The diameters of the motor pulley and the driven pulley are 350 mm and 1370 mm. The center distance is 1370 mm, and both pulleys are made of cast iron. Coefficient of friction of leather on cast iron is 0.35. The allowable stress for the belt is 2.4 MPa, which allows for the factor of safety and also for the fact that a double ply belt does not have double the capacity of a single ply belt. (A double ply belt has approximately 85% the capacity of a single ply belt of the same thickness.) The belt density p =970 kg/m^3. What is the power capacity? (Answer: 39.1 kW ) -0350 -1370
