# What Is a Moment in Statics?

The turning effect of the force on the body on which it is acting is measured by the moment of a force. The moment of a force depends on the magnitude of the force and the distance from the axis of rotation.

## What Is a Moment in Statics?

In statics, a moment is an expression involving the product of the force and the distance from a reference point to the point of interest.

The reference point can be any point in space, but is typically the center of mass of an object or system. The point of interest is typically a point on the body where the force is applied.

The moment can be thought of as the tendency of the force to rotate the body about the reference point. The unit of moment is the newtonmeter (Nm).

The moment of a force about a reference point is equal to the sum of the moments of the force about all other points in space. This is known as the principle of moments.

The principle of moments states that the total moment of a force about any point is equal to the sum of the moments of the force about all other points. This principle is used to solve problems in statics.

The magnitude of the moment of a force can be determined by the equation: M = F d where M is the moment, F is the force, and d is the distance from the reference point to the point of interest.

The direction of the moment can be determined by the righthand rule. The right
