Resultant Force and Couple moment

The resultant force is the combined effect of all forces acting on an object. Or the replacement of all the force by a single force and gives the same effect as the all forces acting in an object known as the resultant force.

Couple moment is the combination of two moments, which has the same magnitude but the direction of both the moments is opposite to each other.
