Question

If a force applied at any point in its line of action and is still creating the same moment about any fixed point say P, then the force is said to be______________

(a) Couple

(b) Sliding vector

(c) Slider couple

(d) Couple slider

The question was asked in class test.

My doubt stems from Moment of a Force in section Force System Resultants of Engineering Mechanics

Answer 1

Correct choice is (b) Sliding vector

For explanation I would say: If a force applied at any point in its line of action and is still creating the same moment about any fixed point say P, then the force is said to be a sliding vector. This is because the moment of the force which is acting on its line of axis at the point P is the same throughout. Whatever be the direction of the distance.
