A flat belt is required to transmit 22 kW from a 250 mm diameter pulley running at 1450 rpm to a 355 mm diameter pulley. The proposed belt is 3.5 mm thick. The other system specifications are as follows: Coefficient of friction 0.7, Density of the belt is 1100 kg/m3, Maximum permissible stress is 7 MPa. The distance between the shafts is 1.8 m.
Calculate the width required.
V belt velocity
according to the power transmitted by the belt
