Question: A uniform beam AB of weight W is standing with the end B on a horizontal floor and end A leaning against a vertical wall. The beam stands in a vertical plane perpendicular to the wall inclined at ${{45}^{o}}$ to the vertical, and is in the position of limiting equilibrium. If the two points of contact are equally rough, then the coefficient of friction at each of them is


1) $\sqrt{2}-1$
2) $\frac{1}{\sqrt{2}}$
3) $\frac{1}{\sqrt{3}}$
4) None of these
