(english) The resultant of a system of forces is a single force or moment whose magnitude, direction, and location make it statically equivalent to the system of forces.
(english) A system of forces which is statically equivalent to a stress distribution over an area.
(english) An object is in equilibrium if the resultant of the system of forces acting on it has zero magnitude. See static equilibrium and dynamic equilibrium.
(english) An system of internal forces whose resultant is a force acting perpendicular to the longitudinal axis of a structural member or assembly: sometimes called shear force.
(english) Two force systems are statically equivalent when their resultants are equal. Physically, this means that the force systems tend to impart the same motion when applied to an object; note that the distribution of resulting internal forces in the object may be different.
(english) The location of the resultant of gravity forces on an object or objects: sometimes called center of mass.

(english) A system of internal forces whose resultant is a moment. This term is most commonly used to refer to internal forces in beams.

(english) A system of internal forces whose resultant is a force acting along the longitudinal axis of a structural member or assembly.
(english) A fictitious force used for convenience in visualizing the effects of forces on bodies in motion. For an accelerating body, the inertial force is considered as a body force whose resultant acts at the object's center of gravity in a direction opposite the acceleration. The magnitude of the force is the mass of the object times the magnitude of the acceleration.
(english) The resultant of a system of forces causing rotation without translation. A moment can be expressed as a couple.
