30 In the figure above, a 24 kg boom of length 3 m is supported by a cable that has a breaking tension of 1050 N. The cable is perpendicular to the boom and is attached 2.25 m from the pivot. Find: a) the maximum load that can be suspended from the end of the boom; N b) The magnitude of the vertical force exerted by the pivot at maximum load? N c) The magnitude of the horizontal force exerted by the pivot at maximum load? N
