Meaning of unstable equilibrium in English:

unstable equilibrium


  • A state of equilibrium in which a small disturbance will produce a large change.

    ‘Instead of exerting the usual restoring force that tries to resist deformation, materials with a negative stiffness draw on the energy stored in their unstable equilibrium state to help the deformation proceed faster.’
    • ‘Solid portions of the curve represent locally stable equilibria whereas dashed portions of the curve represent unstable equilibria.’
