Component 1
The turning effect of a force about a pivot, calculated as force multiplied by the perpendicular distance from the pivot to the force’s line of action.
For moments, use the perpendicular distance from the pivot to the force’s line of action, not automatically the length of the bar.
Measure each moment arm from the pivot, perpendicular to the force’s line of action—not between the effort and load.
Use consistent distance units. Forces are measured in N; moments can be expressed in N m. Mechanical advantage has no unit.

Force in N multiplied by distance in m gives a moment in N m.
