See Figure P12–9. The shaft rotating at 220 rpm carries a spur gear D having 96 teeth with a diametral pitch of 8. The teeth are of the 20°, full-depth, involute form. The gear receives 12.5 hp from a pinion directly below it. Compute the torque delivered to the shaft and the tangential and radial forces exerted on the shaft by the gear. 

Data in Figure P12–9.
