Question

Two pulleys of a 400mm diameter and a 300mm diameter, respectively, are on parallel shafts with 2m apart and wrapped by two methods open and cross, respectively For both wrapping cases, sketch two belt drives and conduct design analyses to determine: a) the total lengths of the belt required and the angles of wrap at two pulleys using both graphic method and analytic method b) the powers can be transmitted by the two belts when the small pulley rotates at 1500 rpm, if the maximum permissible tension in the belt is 2.0kN, and the coefficient of friction between the belt and the pulley is 0.2. c) the speed of the large pulley when the maximum powers could be transmitted d) the differences between two wrapping ways of the belt drive.
