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. If the forces P and P' are removed, are the wedges self-locking? The contacting surface between A and D is smooth.

Given:

W = 8000 lb

θ = 10 deg

μs = 0.4

D. -P' P-
