HYDRODYNAMIC STABILITY
a.
The state or quality of being stable, or firm; steadiness; firmness; strength to stand without being moved or overthrown; as, the stability of a structure; the stability of a throne or a constitution.
v.
Fig.: To move from firmness; to weaken the stability of; to cause to waver; to impair the resolution of.
n.
Incapableness of decomposition; stability; permanence; durability.
n.
That branch of the science of mechanics which relates to fluids, or, as usually limited, which treats of the laws of motion and action of nonelastic fluids, whether as investigated mathematically, or by observation and experiment; the principles of dynamics, as applied to water and other fluids.
n.
The quality or condition of being unstable; want of stability, firmness, or steadiness; liability to give way or to fail; insecurity; precariousness; as, the instability of a building.
n.
Strength; stability.
a.
Pertaining to, or derived from, the dynamical action of water of a liquid; of or pertaining to water power.
a.
Held by a doubtful tenure; depending on unknown causes or events; exposed to constant risk; not to be depended on for certainty or stability; uncertain; as, a precarious state of health; precarious fortunes.
a.
Steadiness or firmness of character, firmness of resolution or purpose; the quality opposite to fickleness, irresolution, or inconstancy; constancy; steadfastness; as, a man of little stability, or of unusual stability.
n.
The quality or state of being stable, or firmly established; stability.
n.
Strength; firmness; stability.
a.
Of or pertaining to katabolism; as, katabolic processes, which give rise to substances (katastates) of decreasing complexity and increasing stability.
n.
Firmness of mind; stability not to be shaken.
n.
The state or quality of being fixed; stability; steadfastness.
n.
A fast sailing vessel with one mast, rigged in most essentials like a sloop. A cutter is narrower end deeper than a sloop of the same length, and depends for stability on a deep keel, often heavily weighted with lead.
n.
A vessel having one mast and fore-and-aft rig, consisting of a boom-and-gaff mainsail, jibs, staysail, and gaff topsail. The typical sloop has a fixed bowsprit, topmast, and standing rigging, while those of a cutter are capable of being readily shifted. The sloop usually carries a centerboard, and depends for stability upon breadth of beam rather than depth of keel. The two types have rapidly approximated since 1880. One radical distinction is that a slop may carry a centerboard. See Cutter, and Illustration in Appendix.
