Homework Statement
The 135-N uniform beam from which 14-N wooden blocks are suspended is pinned to the ground. The beam is then supported by a cable (attached at the center of the beam) to allow the blocks to hang freely.
If the blocks are attached two-fifths and three-fifths of the way up the beam, θc=12° and θb=20°, what tension must the cable supply?
What is the hinge force at the bottom of the beam?

The Attempt at a Solution
I'm not even sure where to begin tackling this problem. The two angles given are throwing me off, so I can't decide when or how to use either and if I should find the hinge forces first or the wire tension. Any help to point me in the right direction would be greatly appreciated!
