A 4800 N wrecking ball is supported by a boom, which may be
assumed to be uniform, and has a weight of 3600 N. As the drawing
shows, a support cable runs from the top of the boom to the
tractor. The angle between the support cable and the horizontal is
32°, and the angle between the boom and the horizontal is
a. Find the tension in the support cable.
b. Find the magnitude of the force exerted on the lower end of the boom at point P
