Ok, so the set up is that there are two memebers. Both are pivoted to a wall in line but at different heights but the join up on the other end. - - - - - - - - - - - the point where the join up is a downward force acting on it of 900 N. Now I know that when there is one freel rotating member the f0orce will have components acting along the member and one acting as a perpendicular torque to the member. I also kow that when the member is not free to rotate that the calculation becomes more complicated however what I don't get is the physics of this situation. How are the forces distributed on two pivotal joined members?
