A uniform rod AB of weight W has its end A on rough horizontal ground and rests at 45∘ to the vertical against a small smooth peg at C , where AC=3/4 AB . If the rod is on the point of slipping in the vertical plane containing the rod, calculate μ , the coefficient of friction between the rod and the ground. If μ=3/4 , calculate the largest vertical downward force which can be applied to the rod at C without disturbing the equilibrium.
