Resultant force

A resultant force is the single force and associated torque obtained by combining a system of forces and torques acting on a rigid body. The defining feature of a resultant force, or resultant force-torque, is that it has the same effect on the rigid body as the original system of forces.

The point of application of the resultant force determines its associated torque. The term resultant force should be understood to refer to both the forces and torques acting on a rigid body, which is why some use the term resultant force-torque.

Usage examples of "resultant force".

To find component forces equal to the composite or resultant force, the sum of the components must equal the resultant.

The resultant force is at right angles to the original forces you exerted.

If you get a lot of weight on top pushing downwards vertically by gravity then there'll be a resultant force sideways on the slope.

The resultant force was enough to lift the lightweight nullthene off the ground like some giant balloon that never quite managed to become airborne.

In the end, the two forces were added together to make a vector, a combined resultant force bearing no trace of its origins.
