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)

The Attempt at a Solution

Did what I did using paint. I think I am suppose to be doing something like this. Now I don't know 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?
