Use the worked example above to help you solve this problem. Auniform horizontal beam 5.00 m long and weighting 2.94 102 N isattached to a wall by a pin connection that allows the beam torotate. Its far end is supported by a cable that makes an angle of53.0° with the horizontal (figure a). If a person weighing 5.93 102N stands 1.40 m from the wall, find the magnitude of the tensionvector T in the cable and the force vector R exerted by the wall onthe beam.

T = N

Rx = N

Ry = N

EXERCISE HINTS: THIS IS WHERE I REALLY NEED HELP!

A person with mass 55.0 kg stands d = 1.90 m away from the wall ona x = 5.85 m beam, as shown in figure d. The mass of the beam is40.0 kg. Find the hinge force components and the tension in thewire.

T = N

Rx = N

Ry = N
