Direction of forces acting on points A, B and C
Maybe more of a physics question but I got the tip to post here and see if someone can help me.
All I need is the direction in which the forces at points A, B and C would be pointing. From there i can do the calculations by myself.
Enclosed should be a sketch of my problem.

The offered bounty is way too low. If you want to decide what a fair bounty should be, just imagine how much time one may need to spend to carefully answer this question and clarify all you doubts, and offer accordingly.

Low bounty and mass or density information is missing

I´m just trying to help a friend...this isn't even for me and I can't afford to pay more.... And if someone knows the answer to this I don't think that it's a lot of work to draw a few arrows....
