Question

A uniform chain of length L has one of its end attached to a vertical wall at point A, while $\frac{3 L}{4}$ of the length of the chain is lying on table as shown in figure. Tangent to the chain at A makes an angle 37° with the wall. Find the minimum coefficient of friction between table and chain so that chain remains in equilibrium.

Resolve the chain weight along the hanging and table portions. At limiting equilibrium, friction balances the horizontal pull transmitted at A. μ min ​ = 4 1 ​ = 0.25
