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

Column D is subjected to a vertical load W. 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 μs. Determine the force P needed to raise the column and the equilibrium force P' needed to hold wedge A stationary. The contacting surface between A and D is smooth.

Units Used:

kip = 103 lb

Given:

W = 8000 lb

θ = 10 deg

μ s = 0.4
