Textbook Question
Chapter 12, Problem 2P
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.
