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 in bending moment diagram is said to be______________

(a) Couple

(b) Sliding vector

(c) Slider couple

(d) Couple slider

I had been asked this question at a job interview.

My query is from Bending Moment Diagram topic in chapter Internal Forces of Engineering Mechanics

Answer 1

Right answer is (b) Sliding vector

The explanation is: 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 the axis at the point P is the same throughout. Whatever be the direction of the distance.
