A flat belt, 8 mm thick and 100 mm wide transmits power between two pulleys, running at 1600 m/min. The mass of the belt is 0.9 kg/m length. The angle of lap in the smaller pulley is 165° and the coefficient of friction between the pulley and belt is 0.3. If the maximum permissible stress in the belt is 2 MN/m2,
Determine :
1. maximum power transmitted ; and
2. Initial tension in the belt.
Discover the maximum torque: Discover the maximum torque that may be transmitted by the shaft of 400 mm diameter, if the shear stress is not to exceed 50 N/mm 2 . Solution
