Definition:Equilibrium (Mechanics)/Neutral

This page is about equilibrium in the context of mechanics. For other uses, see equilibrium.

Definition

Let $B$ be a particle, a system of particles, or a body which is in equilibrium.

Let $B$ be such that if a small displacement is applied, $B$ remains in its new position.

$B$ is then said to be in neutral equilibrium.
