See Figure P12-2. The shaft rotating at \( 200 \mathrm{rpm} \) carries a spur gear C having 80 teeth with a diametral pitch of 8 . The teeth are of the \( 20^{\circ} \), full-depth, involute form. The gear delivers \( 6 \mathrm{hp} \) to a pinion directly below it. a. Compute the torque delivered by the shaft to gear \( \mathrm{C} \) and the tangential and radial forces exerted on the shaft by the gear b. The shaft rotating at \( 200 \mathrm{rpm} \) carries a 6 -in-diameter chain sprocket \( D \) that delivers 4 hp to a mating sprocket above. Compute the torque delivered by the shaft to sprocket \( \mathrm{D} \) and the force exerted on the shaft by the sprocket. c. The shaft rotating at \( 200 \mathrm{rpm} \) carries a 20-in-diameter flat-belt pulley at A that receives \( 10 \mathrm{hp} \) from below. Compute the torque delivered by the pulley to the shaft and the force exerted on the shaft by the pulley. d. Force and Moment Diagrams FlouRE P12-2 (Problems \( 2,12,13 \), and 23)
