A 82-lb sheet of plywood rests on two small wooden blocks as shown. It is allowed to lean 30° from the vertical under the action of a force P which is perpendicular to the sheet. Friction at all surfaces of blocks A and B is sufficient to prevent slipping. Determine the magnitude P and the vertical reaction forces at A and B.
