Figure 5 shows a planetary gear system (gear teeth not shown) used in an automatic transmission. A shaft at O drives the arm OA at a constant clockwise angular speed w about the fixed bearing at O. a) If the ring gear D is fixed, what is the rotational speed of gear B? b) If the ring gear D also rotates, but counterclockwise about O at an angular speed of , what is the rotational speed of gear B? c) What should be the rotational speed, and direction of rotation, of ring gear D for the rotational speed of gear B to be identical to that of arm OA? D Figure 5: Planetary gear system. Figure 5 shows a planetary gear system (gear teeth not shown) used in an automatic transmission.
