A wrecking ball (weight = 4880 N) is supported by a boom, which may be assumed to be uniform and has a weight of 3520 N. As the drawing below shows, a support cable runs from the top of the boom to the tractor.
The angle between the support cable and the horizontal is θ1 = 34.8°, and the angle between the boom and the horizontal is θ2 = 47.0°. Calculate the tension in the support cable.
I think this is a torque problem, I just can't figure out how to find the lengths of the lever arms.
