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 sliding vector. What is the name of this property in a bending moment diagram?

(a) Associative property

(b) Distributive property

(c) Negative associative property

(d) Principle transmissibility of the force

This question was posed to me in unit test.

The doubt is from Bending Moment Diagram in chapter Internal Forces of Engineering Mechanics

Answer 1

The correct answer is (d) Principle transmissibility of the force

For explanation: 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 sliding vector. This is because the moment of the force which is acting on its line of axis at the point P is same throughout. This is known as the principle transmissibility of the force.
