1. The problem statement, all variables and given/known data http://i.imgur.com/5plXa.png 2. Relevant equations ƩFx = 0, ƩFy = 0, ƩM = 0 3. The attempt at a solution I realize that this is an equilibrium problem and that the sum of the forces in the x and y directions is 0, and the sum of the moments is 0. I draw two free body diagrams, one at point A (the contact point between the left wall and beam), and one at point B (the edge). Each FBD has the forces exerted by the bar on the wall - I call it Fa and Fb respectively. Also, both points have normal forces which are perpendicular to the surface. FNa is perpendicular to the wall while FNb is perpendicular to the rod/edge. Also incorporating the weights (Wa and Wb), I get four equations. What I can't figure out is how to formulate an equation for the sum of the moments, and subsequently solving the problem for theta. Any help would be tremendously appreciated.
