What do you understand by the clockwise and anticlockwise moment of force? When is it taken positive?

$A$, $B$ and $C$ are the three forces each of magnitude $4 \mathrm{N}$ acting in the plane of the paper as shown in Figure. The point $O$ lies in the same plane.

Name the forces producing (a) Clockwise (b) anticlockwise moments.

$A$, $B$ and $C$ are the three forces each of magnitude $4 \mathrm{N}$ acting in the plane of the paper as shown in Figure. The point $O$ lies in the same plane.

What is the resultant torque about the point $O$?
