A polyamide conveyor belt is required to transport crushed rocks at a distance of 10 ft at a speed of 3 ft/sec. The maximum weight of the cruched rock on the belt is 150 lb and the coefficient of static friction between the belt and the rock is 0.12. Design a flat belt drive. Assume a gearbox reduces the speed from a 10-hp electric motor running at 1750 rpm to the belt drive.
