A moment is the turning effect of a force.
- Even if the forces acting on a body are balanced in the sense that they do not cause the body to change speed, they can still make the body turn.
moment = force x perpendicular distance between line of action and pivot
(Nm) (newtons) (metres)
- To get the MAXIMUM MOMENT you need to push at RIGHT ANGLES to the spanner.
- Pushing at any other angle means a smaller moment.
- This is as the perpendicular distance between the line of action and pivot is smaller.
