A gear train is shown in the figure below. The gears have following properties: N2 = 20 teeth and P4 = 10; d3 = 6 in.; d4 = 1.5 in, and Pd = 8; and N5 = 48 teeth. Determine the velocity (rpm and direction) of gear 5 as gear 2 drives at 1800 rpm counterclockwise and the center distance between gears 2 and 5. Also determine the pitch line velocity and the circular pitch of the gear pair 4-5. [10+4+5+3 points]
