(Use relative motion analysis): The planetary gear system is used in car transmissions. There is sun gear S, planet gears P and the ring gear R. By locking (fixing/grounding) certain gears you can have different gear ratios and car speeds. a) If the ring gear is held fixed, i.e. wR = 0, and the sun gear is rotated at ws = 5 rad/s, find the angular velocity, wp of the planet gears and wд the output shaft A. b) If the sun gear is held fixed, i.e. ws = 0, and the ring gear is rotated at WR = 5 rad/s, find the angular velocity, wp of the planet gears and wд the output shaft A.
