NOUN
- (shipbuilding) the point of intersection between two vertical lines, one line through the center of buoyancy of the hull of a ship in equilibrium and the other line through the center of buoyancy of the hull when the ship is inclined to one side; the distance of this intersection above the center of gravity is an indication of the stability of the ship
How To Use metacenter In A Sentence
- This introductory course in hydrostatics of ships covers buoyancy, weights, metacenters and stability at small and large angles of heel and trim.
- The metacentric height can be selectively varied by varying the relationship of center of gravity to that of the dipole mass system with respect to the metacenter of the gravity gradiometer.
- Unless there is a dramatic change in the ship's shape at the waterline, the center of gravity remains in place and the new and old transverse metacenters cross at this point.
- This distance is termed a radius because for small heel angles, the locus of successive centers of buoyancy approximates a circular arc, with the transverse metacenter as its center.
- Unless there is a dramatic change in the ship's shape at the waterline, the center of gravity remains in place and the new and old transverse metacenters cross at this point.
- And, if the metacenter should fall below the ship's center of gravity, it'll capsize.
- If the metacenter is below the center of gravity, the boat is unstable and capsizes.
- The curve may be constructed in the following manner: Having found by calculation the position of the transverse metacenter, M, for a given displacement -- Figs. 1 and 2 -- the metacentric height, G M, is then determined either by calculations, or more correctly by experiment, by varying the position of weights of known magnitude, or by the stability indicator itself.

- The metacentric height can be selectively varied by varying the relationship of center of gravity to that of the dipole mass system with respect to the metacenter of the gravity gradiometer.
- When a submarine submerges, however, the water plane disappears and the metacenter comes down to the center of buoyancy.
