With the following simulation, you can practise the moment of forces interactively.
Moment of a force = force X perpendicular distance from the pivot
The resultant moment or the total moment is the algebraic sum of the moments of forces.
In the simulation, the clockwise moment is considered as positive.
To increase the magnitude of a force, drag the end of each force/s up or down. The force that is closest to A can even be moved diagonally.
Move the forces and study the way the total or resultant moment changes.
