The bucket of a backhoe is the element AB of the four-bar linkage system ABCD. Assume that the points A and D are fixed and that, at the instant shown, point B is vertically aligned with point A, point C is horizontally aligned with point B, and point B is moving to the right with a speed υB = 1.2 ft/s. Determine the velocity of point C at the instant shown, along with the angular velocities of elements BC and CD. Let h = 0.66 ft, e = 0.46 ft, l = 0.9 ft, and w = 1.0 ft.
