(a) The shaft of the sun gear in the planetary geartrain is held stationary by a brake (Figure P8.34). Determine the relationship between the rotational speeds of the shafts for the ring gear and carrier. Do those shafts rotate in the same direction or opposite directions?

(b) Repeat the exercise for the case in which the ring gear shaft is instead held stationary.

(c) Repeat the exercise for the case in which the carrier shaft is instead held stationary.
