The coefficient of static friction between A and C and between B and D is μs = 0.24, and between A and B is μs′ = 0.15. Neglect the weight of each wedge. (Figure 1)

Determine the horizontal force P needed to pull out wedge A.

Express your answer to three significant figures and include the appropriate units.

Step 1

Consider *N _{D}* as the normal force by the wall

Draw the free body diagram of block *B*.

Step 2

Calculate the friction force *f _{D}*.

Step 3

Equate the forces in ver...
