To level a wood deck, wood wedges A and B are placed under a corner of the deck. Wedge B rests on a wood board as shown, and a bar clamp is used to apply equal and opposite forces to the wedges. Knowing that θ =18° and that the coefficient of static friction between all wood surfaces is 0.35 and 0.60 between the board and the ground, determine the magnitude P of the clamping forces for which upward motion of the deck is impending.
