Cantilever beams are always in equilibrium, whether you form the equilibrium equations or not.

(a) True

(b) False

This question was addressed to me during an online interview.

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

Right answer is (b) False

The explanation is: The thing is that the formation of the conditions only verifies that the body is in equilibrium or not. Thus if the cantilever is in equilibrium then also the condition needs to be applied. It will be wrong to justify the equilibrium only on the basis of structure.
