Problem on Shaft -
Assuming no frictional losses, a torque of T = 750lb·in is applied through the shaft of gear F in order to drive the roller chain at point B at a constant speed. The chain sprocket has a pitch diameter of 6 in and transmits a force of 500 lb as shown. The pitch diameters of gears C and F are 10 and 5 in, respectively. The contact force between the gear is transmitted through the pressure angle φ = 20o. Considering the bearing supports to be simple supports, determine the reactions at A, D, E, and G.
