Solve Prob. 15.158, assuming that the plate rotates about O with a constant clockwise angular velocity ω. Problem 15.158: Four pins slide in four separate slots cut in a circular plate as shown. When the plate is at rest, each pin has a velocity directed as shown and of the same constant magnitude u. If each pin maintains the same velocity relative to the plate when the plate rotates about O with a constant counterclockwise angular velocity ω, determine the acceleration of each pin.
