Question

In the figure above, a 34 kg boom of length 5 m is supported by a cable that has a breaking tension of 1200 N. The cable is perpendicular to the boom and is attached 3.75 m from the pivot. Find: the maximum load that can be suspended from the end of the boom; The magnitude of the horizontal force exerted by the pivot at maximum load? ;The magnitude of the vertical force exerted by the pivot at maximum load?
thank you.
