A worker of mass mw = 68 kg sits on the beam at a distance x from support A. Refer to the figure, though note that it is not drawn to scale. a. When the worker sits at a distance x = 7.5 m from support A, calculate the force, in newtons, that support B must exert on the beam in order for it to remain at rest. Use g with three significant figures. b. The force exerted on the beam by support A is measured and found to be FA = 2240 N. At what distance x, in meters, from support A is the worker sitting now?A 200 N sign hangs from the middle of a cable between two buildings.
