Ship - Buoyancy

Buoyancy

See also: Buoyancy

A floating boat displaces its weight in water. The material of the boat hull may be denser than water, but if this is the case then it forms only the outer layer. If the boat floats, the mass of the boat (plus contents) as a whole divided by the volume below the waterline is equal to the density of water (1 kg/l). If weight is added to the boat, the volume below the waterline will increase to keep the weight balance equal, and so the boat sinks a little to compensate.

Famous quotes containing the word buoyancy:

    “She keeps
    The Topic over intellectual deeps
    In buoyancy afloat. They see no ghost.
    With sparkling surface-eyes we ply the ball:
    It is in truth a most contagious game:
    Hiding the Skeleton, shall be its name.”
    —George Meredith (1828–1909)

    “The boatmen appeared to lead an easy and contented life, and we thought that we should prefer their employment ourselves to many professions which are much more sought after. They suggested how few circumstances are necessary to the well-being and serenity of man, how indifferent all employments are, and that any may seem noble and poetic to the eyes of men, if pursued with sufficient buoyancy and freedom.”
    —Henry David Thoreau (1817–1862)
