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

The Space Shuttle system consists of four primary elements : an orbiter spacecraft, two Solid Rocket Boosters(SRB), an external tank to house fuel and oxidizer and three Space Shuttle main engines.... The Shuttle will transport cargo into near Earth orbit 100 to 217 nautical miles(115 to 250 statute miles) above the Earth. This cargo or payload is carried in a bay 15 feet in diameter and 60 ft long. Major system requirements are that the orbiter and the two solid rocket boosters be reusable.... The orbiter has carried a flight crew of up to eight persons. A total of 10 persons could be carried under emergency conditions. The basic mission is 7 days in space. The crew compartment has a shirtsleeve environment, and the acceleration load is never greater than 3 Gs. In its return to Earth, the orbiter has a cross-range maneuvering capability of 1, 100 nautical miles(1, 265 statute miles). The Space Shuttle is launched in an upright position, with thrust provided by the three Space Shuttle engines and the two SRB. After about 2 minutes, the two boosters are spent and are separated from the external tank. They fall into the ocean at predetermined points and are recovered for reuse. 4, record 3, English, - space%20shuttle

La navette spatiale Américaine [...] est un véhicule de l'espace mis au point par La NASA, l'Agence spatiale Américaine. La navette peut décoller comme une fusée, verticalement, se mettre en orbite autour de la Terre pour remplir des missions et revenir sur Terre en atterrissant comme un avion, horizontalement. Contrairement aux fusées la navette peut resservir 100 fois. Elle peut transporter un équipage de spationautes pour rejoindre une station spatiale comme MIR ou la station international Alpha, transporter un satellite à mettre en orbite autour de la Terre ou une sonde à envoyer dans l'espace. La navette peut également se transformer en station spatiale. Elle transporte alors un laboratoire, Spacelab, qui est utilisé pour faire des expériences en impesanteur. La première navette a été lancée le 12 Avril 1981. Elle s'appelait Columbia. Vinrent ensuite Challenger, Discovery et Atlantis. En 1991 la navette Endeavour a été mise en service. 4, record 3, French, - navette%20spatiale%20am%C3%A9ricaine

La navette comporte trois parties : (1) La partie principale qui peut resservir plusieurs fois est appelée l'orbiteur. C'est cette partie qui ressemble à un avion à aile delta. L'orbiteur transporte les passagers et la cargaison. (2) Les deux fusées servent seulement au décollage. [Elles] sont ensuite récupérées et réutilisées. (3) Un énorme réservoir qui contient le comburant (oxygène liquide) et le carburant (hydrogène liquide) nécessaires au fonctionnement des moteurs des trois fusées de la navette. [Ces fusées] servent à mettre la navette en orbite. 4, record 3, French, - navette%20spatiale%20am%C3%A9ricaine

If the pressure within the tail rotor servo system exceeds 55 bar, the check valve opens the pressure line to return and allows a partial hydraulic flow as the servo piston returns to the extend position.
