The center-to-center distance of the shafts is 2 m, and the speeds of the driving and driven shafts are 100 rpm and 240 rpm respectively. The radius of the smaller pulley is 300 mm and the coefficient of friction between the belt and the pulley is 0.2. The width of the belt is 150 mm and thickness of the belt is 12 mm. Determine the stress in the belt for an open belt drive and for a cross belt drive.
