Question:

Solve Prob. 6.96 assuming that the 16-kip load has been removed. Problem 6.96: The cab and motor units of the front-end loader shown are connected by a vertical pin located 60 in. behind the cab wheels. The distance from C to D is 30 in. The center of gravity of the 50-kip motor unit is located at Gm, while the centers of gravity of the 18-kip cap and 16-kip load are located, respectively, at Gc and Gl. Knowing that the machine is at rest with its brakes released, determine

(a) The reactions at each of the four wheels,

(b) The forces exerted on the motor unit at C and D.
