Determine the force P acting on the cord which is required to maintain equilibrium of the horizontal

Question:

Determine the force P acting on the cord which is required to maintain equilibrium of the horizontal bar CB of mass M. Hint: First show that the coordinates sA and sB are related to the constant vertical length l of the cord by the equation 5sB − sA = L.

Given:

M = 20 kg
