Question:

To level a wood deck, wood wedges A and B are placed under a corner of the deck, and wedge B rests on a wood board as shown. Knowing that the coefficient of static friction between all wood surfaces is 0.35 and 0.60 between the board and the ground, determine the maximum value of the wedge angle θ for which the system will remain in equilibrium after the clamping forces P and €“P are removed.
