Physics

A uniform beam of length 1.0 m and mass 16 kg is attached to a wall by a cable that makes an angle of 30 degrees with the end of the beam, as shown in the figure. The beam is free to pivot at the point where it attaches to the wall. What is the tension in the cable?

  1. Sum moments around the beam end at the wall.

    mg*L/2-Tension*sin30=0

    solve for tension.

  2. error. Change the second term to Tension*length*sin30.
