1. 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. Pulley A receives 10 hp from below. The chain sprocket D delivers 4 hp to a shaft above. Compute the torque delivered by the shaft to gear C and the tangential and radial forces exerted on the shaft by the gear. The pitch diameters of the flat belt sheave, spur gear, and the chain sprocket are 20 in., 10 in., and 6 in., respectively. Ans: TA 3150 in-lb, To = lb, W, 137.6 lb = = TD 1890 in-lb, Tp = 1260 in-lb, W₁ = 378

Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?
