Aprinciple of independence of forces
-
Bprinciple of resolution of forces
-
Cprinciple of transmissibility of forces
-
Dnone of these
Answer
Correct Answer: principle of resolution of forces
Explanation
Concept/ApproachThe principle of resolution of forces states that the components of vectors add: the sum of components of individual forces along any axis equals the component of their vector sum (resultant) along that axis.
Why others are wrongIndependence of forces concerns motion in perpendicular directions.Transmissibility permits moving a force along its line of action without changing external effects.
