Metacentre

Metacentre
Metacenter Met`a*cen"teror Metacentre Met`a*cen"tre, n. [Pref. meta- + center.] (Hydrostatics) The point of intersection of a vertical line through the center of gravity of the fluid displaced by a floating body which is tipped through a small angle from its position of equilibrium, and the inclined line which was vertical through the center of gravity of the body when in equilibrium. [1913 Webster]

Note: When the metacenter is above the center of gravity, the position of the body is stable; when below it, unstable. [1913 Webster]
