Awrecking ball (weight = 4800 N) is supported by a boom, which maybe assumed to be uniform and has a weight of 3600 N. As the drawingshows, a support cable runs from the top of the boom to thetractor. The angle between the support cable and the horizontal is32 degrees, and the angle between the boom and the horizontal is 48degrees. Find

(a) the tension in the support cable and

(b) themagnitude of the force exerted on the lower end of the boom by thehinge at point P.
