Principle of Buoyancy and Stability

1.  Archimedes Principle’s Law: a body floating or submerged in a fluid is buoyed up by a force equals to the weight of the water it displaces.

2.  Depth to which vessel sinks depends on density of water (r = 1 ton/35ft³ seawater, or 1.025 tonnes/m3), vessel sinks until weight of water displaced by the underwater volume is equal to the weight of the vessel.
