♥ Moment Of A Force
When we push or pull a door, we are applying a force that causes a turning effect to accomplish a task.
This turning effect is called the moment of a force, and is used to make work easier.
The moment of force at a fulcrum or pivot, which is the point of rotation, is defined by the following equation:
Moment of force, M = F X D Moment of force,
M = Force X Perpendicular distance from the fulcrum to the line of action of the force ( N m )
Since the S.I. units for force and distance are newton ( N ) and metre ( m ), the moment of force has a derived unit of newton-metre (N m).
