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 the bucket rotates with a constant angular velocity ωAB = 0.25 rad/s. In addition, suppose that, at the instant shown, point B is aligned vertically with point A, and C is aligned horizontally with B. Determine the acceleration of point C at the instant shown along with the angular accelerations of the elements BC and CD. Let h = 0.66 ft, e = 0.46 ft, l = 0.9 ft, and w = 1.0 ft.
