Question

Which of the following is correct?

(a) The application of the conditions of the equilibrium of the body is valid only in the 2D

(b) The application of the conditions of the equilibrium of the body is valid only in the 3D

(c) The application of the conditions of the equilibrium of the body is valid only in the 1D

(d) The application of the conditions of the equilibrium of the body is valid throughout

I have been asked this question in a national level competition.

The doubt is from Conditions for a Rigid-Body Equilibrium topic in division Equilibrium of a Rigid Body of Engineering Mechanics

Answer 1

The correct answer is (d) The application of the conditions of the equilibrium of the body is valid throughout

The best I can explain: The application of the conditions of the equilibrium of the body is valid throughout. This means that the conditions are irrespective of the dimensions. The conditions are the basic rules that define the equilibrium of the body and thus are applicable in any dimension of the real axis.
