Homework Statement

There's a diagram with a rough free body diagram implemented.

Homework Equations

This is what I'm really unsure about.

The Attempt at a Solution

Finding Compression at BC: mg*sin(60) = 8495N
Tension AC = mg*cos(25) = 8890N

Not sure if that's right, but, it's all I can come up with!

Please help!

At point C, what is the direction of:

1. The reaction force of the beam?
2. The reaction force of the upper part of the cable?
3. The force applied by the lower part of the cable?

How do I find them?

Each of those has only two possibilities. Consider both, choose one that makes physical sense.
