A ship's center of stability is known as the metacentre. If you add weight to the side of a ship the moment created will cause it will roll. There has to be a restoring moment otherwise the ship will capsize. This restoring moment is due to the change in the submerged volume, hence change in center of buoyancy. This acts at the 'center of stability' where BM(distance from center of buoyancy to metacenter) = Inertia/DisplacementPicture a model of a yacht with a large weight attached to the mast. Now move the weight onto the keel. Which one do you think has the best stability?
because without stability the ship is not sea worthy and most likely to capcize. stability is the ability of a ship to keep the ship always in the upright position.
Because the weight of the water it displaces is more than the weight of the ship itself.============================Because the weight of the water it displaces exactly equals the weight of the shipitself. Think of the water that was originally occupying the place where the ship nowis. That water didn't sink because it was supported by the overall pressure frombelow. Putting the ship there means that the force balance is precisely the same.Remember, compared with solid iron, a ship is mostly empty space.
Capsizing. However, the ship can regain its stability.
use a rudder
It will capsize and most likely sink
The weight of the ship plus the weight of the cargo cannot be greater than the weight of the water displaced
i am sure it is to be down at the stern slightley
Weight of ship = weight of (displaced) water.
it balances the weight of the ship out
Because the weight of the water that they displace is greater than the weight of the ship.
