Question:

See Figure P12–4. The shaft rotating at 120 rpm carries a spur gear A having 80 teeth with a diametral pitch of 5. The teeth are of the 20°, full-depth, involute form. The gear receives 40 hp from a pinion to the right as shown. Compute the torque delivered to the shaft and the tangential and radial forces exerted on the shaft by the gear.

Data in Figure P12–4.
