A man standing on the right-hand side pan of a beam balance is counter balanced by a weight placed on the other pan. Weight of the man is W and the length of the beam of L. Will the equilibrium be disturbed if the man standing on the pan begins to pull a rope tied to a distance of L/4 from this side of the pan, with a force P < W. The rope makes an angle of θ to the vertical. Neglect the weight of the rope and beam.
