a 10-m uniform beam of weight 100N is supported by two ropes at the ends. If a 400N erson sits at 2.0 m from the left end of the beam, what is the tension in the right rope?

    Sum the moments about any point. I will do it from the left end.

    solve for Tright.

    Now, sum the forces vertically.

    Tleft+Tright-100N-400N=0 solve for Tleft.
