The semicircular 5-kg plate rotates about a fixed bearing at 0 that can exert a maximum frictional moment of 1.2 N ·m on the plate. The horizontal force P is applied to a cord wrapped around the plate periphery and pinned at A. (a)(a) With P = 0, determine the maximum angle 'theta' for which equilibrium is possible. (b) From the position determined in(a) calculate the force P required to rotate the body counter clockwise.
