Question: For the planetary gear train shown: N2 = 20t, N4 = 40t, N5 = 18t, 6 = 36t, N7 = 154t. 3 is the

For the planetary gear train shown: N2 = 20t, N4 = 40t,

For the planetary gear train shown: N2 = 20t, N4 = 40t, N5 = 18t, 6 = 36t, N7 = 154t. 3 is the arm (carrier) connecting planet gears N4 and N5. The ring gear angular velocity is 100 rpm ccw with an arm angular velocity of 50 rpm cw, 7 154T 40T 36T W7 20T 3 18T a. Determine the angular velocity of planet gear 5. What are the gear sets and gear ratio for this question? b. Determine the angular velocity of the sun gear. What are the gear sets and gear ratio for this question? C. Given the sun gear provides a torque of 450 lb-in, what is the output torque of the ring gear?
