See Figure P12–9. The shaft rotating at 220 rpm carries a spur pinion C having 60 teeth with a diametral pitch of 10. The teeth are of the 20°, full-depth, involute form. The pinion delivers 5 hp to a gear directly above it. Compute the torque delivered by the shaft to pinion C and the tangential and radial forces exerted on the shaft by the pinion. 

Data in Figure P12–9.
