See Figure P122. The shaft rotating at 200 rpm carries a spur gear C having 80 teeth

Question:

See Figure P12–2. The shaft rotating at 200 rpm carries a spur gear C having 80 teeth with a diametral pitch of 8. The teeth are of the 20°, full-depth, involute form. The gear delivers 6 hp to a pinion directly below it. Compute the torque delivered by the shaft to gear C and the tangential and radial forces exerted on the shaft by the gear.

Data in Figure P12–2.
