Question

A uniform horizontal beam 5.00 m long and weighting 2.88 102 N is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 53.0° with the horizontal (Figure (a)). If a person weighing 5.99 102 N stands 1.40 m from the wall, find the magnitude of the tension vector T in the cable and the force vector R exerted by the wall on the beam.
