Question

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 40 mm OR car speeds a) If the ring gear is held fixed, i.e. aR -0, and the sun gear is rotated at ws - 5 rad/s, find the angular velocity, ωΡ。f the planet gears and the output shaft A. b) If the sun gear is held fixed, ie. ωs-0, and the ring gear is rotated at ωR_ 5 rad/s, find the angular velocity, wp of the planet gears and wA the output shaft A. c) If the output shaft is held fixed, i.e. wA- 0, and the ring gear is rotated at ωR- 5 rad/s, find the angular velocity, wp of Ct) 80 mm the planet gears and ws the sun gear. 40 mm d) What if the planet gears are held fixed
