A wrecking ball (weight = 5910 N) is supported by a boom, which may be assumed to be uniform and has a weight of 2820 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 48°. Find (a) the tension in the support cable and (b) the magnitude of the force exerted on the lower end of the boom by the hinge at point P.
I have been having trouble trying to finf the tension, not sure how I originally thought to just do the sum of the torques but it's not coming out. I thougit was just T = 3/4 sin 90 ? very confused?
