Question

The generation of equal equations available for equilibrium as the unknown loadings always guarantees the stability of the body.

(a) True

(b) False

I got this question in a job interview.

This question is from Constraints and Statical Determinacy in section Equilibrium of a Rigid Body of Engineering Mechanics

Answer 1

Right answer is (b) False

To explain: The generation of equal equations available for equilibrium as the unknown loadings doesn’t always guarantees the stability of the body. It is defined on the basis of the supports that are their supporting the body. Or it also depends on the types of the forces that are acting, i.e. the three or two force system.
