I need to mount a heavy panel against a wall. The panel will be first mounted on two legs which go from the top of the panel to the floor. These legs will transfer most of the panel's weight to the floor, and will also be bolted to the wall to prevent the panel falling forward. Since there are only two legs (behind the panel), there will be some force exerted on the bolts and thus on the wall as the panel tries to fall forward.
How do I calculate this horizontal force exerted on the wall?
