The 18-tooth pinion in Figure P15.25 is driven 800 rpm by a motor that delivers 20 lb # in. of torque. The gears provide a double reduction in speed, with output taken from the 36- tooth gear. Both the 6-pitch and 9-pitch gears have a 25° pressure angle. Neglecting the small friction loss in the gears and bearings, determine the radial loads applied to countershaft bearings A and B. Sketch the countershaft as a free body in equilibrium. [Partial ans.: Radial load on bearing B is 35.17 lb]
