A uniform beam $AB$ of length $2l$ rests with end $A$ in contact with rough horizontal ground. A point $C$ on the beam rests against a smooth support. $AC$ is of length $\frac{3l}{2}$ with $C$ higher than $A$, and $AC$ makes an angle of $60$ degree with the horizontal. If the beam is in limiting equilibrium, find the coefficient of friction between the beam and the ground.

Can anyone draw out the diagram for me ? I can't visualize it.
