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 w5.
For ω1 = 60 rpm clockwise (cw) when looked from the left, what is the angular velocity of the carrier and its direction so that Gear 4 rotates in counterclockwise (ccw) direction at twice the angular velocity of Gear 1 when looked from the left
(A) 130 rpm, cw
(B) 223 prm, ccw
(C) 256 rpm, cw
(D) 156 rpm, ccw
