Common Data Questions:
A planetary gear train has four gears and one carrier. Angular velocities of the gears are
ω1,ω2,ω3, and ω4, respectively. The carrier rotates with angular velocity
ω5
For
ω1=60 rpm clockwise (cw) when viewed from the left, what is the angular velocity of the carrier and its direction so that Gear 4 rotates in conuterclockwise (ccw) direction at twice the angular velocity of Gear 1 when viewed from the left?
