Finding the Weight

  1. Oct 6, 2014 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    Something around the lines of this?
    ForceY=force(a-b)*sin(some angle) -orce(b-c)sin(some angle)+force(c-d)sin(some angle)

    3. The attempt at a solution

    Did what I did using paint. I think I am suppose to be doing something like this. Now I dunno where to go from here.

    Try drawing a free body diagram for each vertex.
    Remember the vector sum of the forces has to be zero.

    Start at point G - it has two cables with tension T holding it up and the weight W prulling down for 2T=W.

    At point F - there is 3T down and some force F(FD) pointing up ... get the idea?
