determine the following of a V-belt

Question

The following information applies to a V-belt drive transmitting 35 kW: Effective diameter of motor pulley = 875mm Speed of the motor pulley = 825 r/min The V-groove angle of the pulley = 43 degrees Coefficient of friction = 0.27 Contact angle of the belt = 187 degrees Mass of the belt = 0.98 Kg per meter length Maximum allowable tension per belt = 735 N Efficiency of the drive = 79% Determine the following: 1. The belt speed 2. The centrifugal force 3. The input power 4. The tension in the tight and slack sides of the belt 5. The number of V-belts
