$A5m$ beam $($AD$)$ is shown below with two forces and a free moment acting upon it$.$

The force at point $B$ is $2N$ acting down at a $60$ degree angle and the force at point $C$

is $3N$ up$.$ The free moment is $13Nm.$ The distance from $A$ to $B$ is $2m$ and the

distance from $A$ to $C$ is $4m.$ Replace the loading system acting on the beam by an

equivalent resultant force and couple moment at point $A.$
