The elements of a simplified clam-shell bucket for a dredge are shown. The cable which opens and closes the bucket passes through the block at O. With O as a fixed point, determine the angular velocity ω of the bucket jaws when θ = 45° as they are closing. The upward velocity of the control cable is 0.5 m/s as it passes through the block.
