B F w WC C E The mechanism for a car window winder is shown below. The crank gear C has radius r = 0.600 in, the spur gear attached at point B has radius r2 = 3.60 in, and the lift arms', AB and EF, length is 7 = 9.40 in. Lift arm AB is attached to the spur gear such that the two rotate together about point B. If the crank is turned with an angular velocity wc = 0.600 rad/s, what is vw, the magnitude of the velocity of the window, vw, when the lift arms are at an angle = 29.0 ?
