A uniform rod AB of length 2a and weight W is inclined at 30 degrees to the horizontal with its lower end A on a rough horizontal ground, the angle of friction being 30 degrees. The rod rests in contact with a smooth peg C (AC < AB).
Calculate the height of the peg above the ground and the reaction at the peg if the rod is in limiting equilibrium.
