The Principle of Transmissibility is useful in force analysis because it: Allows the determination of the internal forces acting on an object by a force applied to it. Allows making

calculations about the external effects of a force on an object by considering the force to be applied at any point along its line of action. States that the effect of a force external to a rigid body can be calculated by transmitting the point of action of the force to any point on the body. O States that the force may be applied at any point perpendicular to its given line of action without altering the resultant effects of the force external to the rigid body on which it acts.
