A crossed belt drive is to transmit 10 hp at 900 rpm of the smaller pulley. The smaller pulley has diameter 10 inches, the velocity ratio is 2. and the center distance is 45 inches. It is desired to use a flat belt-inch thick with an expected coefficient of friction of 0.27. If the maximum allowable stress in the belt is 245 psi, determine the necessary leather belt width. Also, find the stress on the slack side. The leather weighs 0.035 lb/in.
