In an epicyclic gear train, as shown in the Fig, the wheel C is keyed to the shaft B and wheel F is keyed to shaft A. The wheels D and E rotate together on a pin fixed to the arm G. The number of teeth on wheels C, D, E and F are 35, 65, 32 and 68 respectively. If the shaft A rotates at 60 r.p.m. and the shaft B rotates at 28 r.p.m. in the opposite direction, find the speed and direction of rotation of arm G.

Answer:
104.5
Step-by-step explanation:
Since the speed of gear B is 200 r.p.m., therefore from the fourth row of the table,
y = 200 ...(i)
Also, the speed of road wheel attached to axle Q or the speed of gear D is 210 r.p.m., therefore from the fourth row of the table,
y – x = 210 or x = y – 210 = 200 – 210 = – 10
∴ Speed of road wheel attached to axle P
= Speed of gear C = x + y
= – 10 + 200 = 104.5 r.p.m
