Stable equilibrium
| (Mech.) | the kind of equilibrium of a body so placed that if disturbed it returns to its former position, as in the case when the center of gravity is below the point or axis of support; - opposed to unstable equilibrium, in which the body if disturbed does not tend to return to its former position, but to move farther away from it, as in the case of a body supported at a point below the center of gravity. Cf. Neutral equilibrium, under Neutral. |
