A uniform 6.61 m long horizontal beam that weighs 454N is attached to a wall by a beam connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 60° with the horizontal and a 565N person is standing 1.07m from the pin. Find the tension (Ft) in the cable by assuming that the origin of the coordinate system is at the rod´s center of mass.
