The 50-kg glass tabletop rests on the centrally located equilateral triangular frame which is supported by three legs. Determine the smallest vertical force P that, when applied to the glass, would cause it to lift or topple off the frame. Specify the force location r and the smallest angle θ, and also determine the vertical reactions of the legs on the floor when tipping is about to occur.
