The Geneva wheel A provides intermittent rot motion coA for continuous motion ωA = 2 rad/s of disk D By choosing d = 100 mm, the wheel has zero angular velocity at the instant pin B enters or leaves one of the four slots. Determine the magnitude of the angular velocity ωA of the Geneva wheel at any angle θ for which pin B is in contact with the slot.
