TOPIC 04-FORCES IN EQUILIBRIUM

Moment of a Force

Is the product of the force applied and the perpendicular distance from a fixed point or pivot

Moment of a force is the turning effect of the force about a point

Moment of force = force x perpendicular distance from pivot

∴ 𝑴 = 𝑭 𝒙 𝒅

The SI unit of moment of force is Newton metre (Nm)

See the figure below

NB:

The point where the object rotates after turning force is called pivot or fulcrum
Moment of force is applied in different activities such as opening bottle caps, door opening and tightening nuts etc
The moment of a force depends on the following

Size of a force
Perpendicular distance
