1.30P Moments equation
Know and use moment = force × perpendicular distance from the pivot.
Concept essentials
- Moment is the turning effect of a force about a pivot.
- Moment equals force multiplied by perpendicular distance from the pivot.
- The distance used must be perpendicular to the force’s line of action.
- Newton metres and newton centimetres are both valid when units are used consistently.
- A moment is increased by increasing the force or increasing the perpendicular distance.
