Hi Guys,

I am stuck on a problem out of my text book, hope you guys can help!
In the epicyclic gear train shown, sun gear A rotates at 1000rpm clockwise while the ring gear E rotates at 500 rpm counter clockwise.

The number of teeth are as follows:
A:30 teeth
B:20 teeth
E: 80 teeth

Gears B and C are compounded and can rotate freely on the carrier connected to the shaft F. Al gears are of the same pitch. Determine:

(a)The umbers of teeth on the ring gear D and on gear C.

ANS: 70 and 30 teeth.
