Question: Column D is subjected to a vertical load of 8000 lb. It is supported on two identical wedges A and B for which the coefficient

Column D is subjected to a vertical load of 8000 lb. It is supported on two identical wedges A and B for which the coefficient of static friction at the contacting surfaces between A and B and between B and C is ?_s = 0.4. Determine the force P? needed to raise the column and the equilibrium force needed to hold wedge A stationary. The contacting surface between A and D is smooth.
