A V-belt drive consist of five V-belts In parallel on grooved drive and driven pulleys of diameter 900 mm and 350 mm respectively. The drive pulley operates at 800 rpm. The center distance is 1.5 m and the pulleys made of different material. The angle of groove A is 36 and the coefficient of friction between belt and drive and driven pulleys are 0.12 and 0.25 respectively. The cross-sectional area of each belt is 950 mm, the permissible safe stress in the material is 4.5 MPa and the mass of each belt is 1.75 kg/m. Calculate the power that can be transmitted and design the grooved pulleys. ir cox bu
