If in the gear train for Problem 7.28, gear 2 rotates at 1000 rpm in the direction shown
If in the gear train for Problem 7.28, gear 2 rotates at 1000 rpm in the direction shown and gear 5 is held stationary, arm 6 will rotate at 625 rpm in the same direction as gear 2. Determine the speed and direction of rotation which must be given to gear 5 to make arm 6 stand still if gear 2 continues to rotate at 1000 rpm.
Problem 7.28
In the planetary gear train shown in Fig. 7.42, gear 2 turns at 600 rpm in the direction indicated. Determine the speed and direction of rotation of arm 6 if gear 5 rotates at 350 rpm in the same direction as gear 2.
