A uniform 8.0 m, 1500kg beam is hinged to a wall and supportedby a thin cable attached 2.0m from the free end of the beam. Thebeam is supported at an angle of 30.0 degrees above thehorizontal.

(a) Make a free-body diagram of the beam.

(b) Find the tension in the cable.

(c) How hard does the beam push inward on thewall.

A uniform, horizontal beam of length 6.0m and weight 120N is attached at one end to a wall by a pin connection (so that it may rotate). A cable attached to the wall above the pin supports the opposite end. The cable makes an angle of 60degrees with the horizontal. What is the tension in the cable needed to maintain the beam in equilibrium?

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
