The state in which a disturbance may cause a body (or a system) to be displaced from its rest position, assuming a new position of equilibrium; left alone the body (or the system) does not return to its original position.  2, record 1, English, - neutral%20equilibrium

equilibrium : state of balance. When a body or a system is in equilibrium, there is no net tendency to change. In mechanics, equilibrium has to do with the forces acting on a body.... However, a state of equilibrium does not mean that no forces act on the body, but only that the forces are balanced.... The stability of a body is a measure of its ability to return to a position of equilibrium after being disturbed. It depends on the shape of the body and the location of its center of gravity... A body with a large flat base and a low center of gravity will be very stable, returning quickly to its position of equilibrium after being tipped. However, a body with a small base and high center of gravity will tend to topple if tipped and is thus less stable than the first body. A body balanced precariously on a point is in unstable equilibrium. Some bodies, such as a ball or a cone lying on its side, do not return to their original position of equilibrium when pushed, assuming instead a new position of equilibrium; these are said to be in neutral equilibrium.  1, record 1, English, - neutral%20equilibrium

Équilibre d'un corps. Un système est dit en équilibre stable si, écarté de sa position d'équilibre initiale, il y revient de lui-même. Un système est dit en équilibre instable lorsque, écarté de sa position d'équilibre initiale, l'écart s'amplifie naturellement. Un système est dit en équilibre indifférent lorsque, écarté de sa position d'équilibre initiale, il reste dans la nouvelle position qui lui a été donné.  1, record 1, French, - %C3%A9quilibre%20indiff%C3%A9rent

Cuando un cuerpo es ligeramente apartado de su posición, puede comportarse de tres modos diferentes que constituyen otras tantas formas de equilibrio: si vuelve por sí mismo a la posición primitiva es que se halla en equilibrio estable; si se queda inmóvil en la mueva posición, se halla en equilibrio indiferente [...].  1, record 1, Spanish, - equilibrio%20indiferente

Forbes used the inverted pendulum, mounted on a stiff wire, to provide a sensing element in weakly-stable equilibrium, without having to use a very long common pendulum. An upright inverted pendulum, by itself, is in unstable equilibrium. A slight motion topples it over. When the inverted pendulum is mounted on a suitably stiff wire, the apparatus may be rendered stable, so that the inverted pendulum returns to an upright position after having been disturbed.  2, record 2, English, - inverted%20pendulum

On the other hand, a ball can be poised in unstable equilibrium on a pencil' s point. When the initial position is near this equilibrium, the ball seems to be pushed away, before converging to stable equilibrium elsewhere. The set of all unstable equilibrium states, plus their limit points, is called repeller.  3, record 3, English, - repeller

A film often thins gradually to a thickness at which it either ruptures or converts abruptly to an equilibrium film. Rupture under these conditions characterizes unstable films, whereas transition to an equilibrium film characterizes metastable films.  1, record 4, English, - metastable%20film

Un film s'amincit souvent d'une façon graduelle pour atteindre une épaisseur à laquelle il se rompt ou se transforme brusquement en un film à équilibre.
