The Formula Method
It is no necessary to tabulate the solution to an Epicyclic train. The velocity difference
Formula can be solved directly for the train ratio. We can rearrange equation 9.12 (p. 4641
In solve for the velocity difference term. Then. ki (Of represent the angular velocity of
The tire gear in the train (chosen at either end), and 0L represent the angular velocity of
The last gear in the train (at the other end).
