The semicircular 5-kg plate rotates about a fixed bearing at O 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) With P = 0, deter- mine the maximum angle () for which equilibrium is possible. (b) From the position determined in (a) calculate the force P required to rotate the body counterclockwise.
