  • frPoint par lequel passe la force de poussée d'Archimède s'exerçant vers le haut sur un corps immergé ou flottant, correspondant au centre de gravité du volume de fluide déplacé.

The centroid of the displaced volume of fluid in which a body is immersed; the point through which the buoyant force acts upward on a floating or submerged object.

    The point through which the resultant buoyant force acts on a submerged or floating body, equivalent to the centroid of the displaced fluid volume.

    • The centre of buoyancy must be calculated to ensure the ship's stability.
    • For a fully submerged object, the centre of buoyancy coincides with the centre of mass of the displaced fluid.
    • Engineers adjust the hull design to shift the centre of buoyancy for better balance.
