Finding Equilibrium in a Hanging Beam System

[Bugz666]

Homework Statement

In the figure a 6.00-m-long, uniform beam is hanging from a point to the right of its center. The beam weighs 138 and makes an angle of with the vertical. At the right-hand end of the beam a concrete block weighing is hung; an unknown weight hangs at the other end.
If the system is in equilibrium, what is w ? You can ignore the thickness of the beam.
