EQUILIBRIUM
Moment of a force
The moment of a force about a point is given by the product of the force's magnitude and the perpendicular distance between the line of action of the force and the point.
The perpendicular distance between the line of action of the force 'F' and the point 'O' is 'd'.
The moment of the force is therefore = force x Distance.
Moment of force = Force x Distance (N X m)
The SI unit of moment of a force is Nm
Example
1. The line of action of a force 48N is at a perpendicular distance of 1.5m from the point. Find the moment of the force about the point.
