equilibrism (ekwilibrizm)

[ equilibrist (e-kwi-li'brist), n. [= F. équili briste Sp. Pg. equilibrist a ; as L. æquilibris , ter is said to be one of stable equilibrium; when a body, on the contrary, once removed, however slightly, from position of equilibrium, tends to depart from it more and more, like a needle balanced on its point, its position is said to be one of unstable equilibrium; and when a body, more or le from its position of equilibrium, being moved more will rest in any of the positions in which it is placed, and is indifferent to any particular position, its equilibrium is said to be neutral or indifferent. A perfect sphere, of uni form material, resting upon a horizontal plane, is in a state of neutral equilibrium; an oblate spheroid with its axis of rotation vertical is in stable equilibrium; while a prolate spheroid with its axis vertical is in unstable equilibrium on the same plane. A body suspended by its center of gravity is in a state of neutral or indifferent equilibrium. If a body is suspended by any other point, it will be in a state of stable equilibrium when its center of gravity is perpendicularly below the point of suspension; but if the center of gravity is above the point of suspension, the equilibrium will be unstable.

[NL., If any forces, acting on a solid or fluid body, produce mules, but also occasionally in other domestic equilibrium, we may suppose any portions of the body to become fixed without destroying the equilibrium. Thomson and Tait, Nat. Phil., § 564. When at rest under the action of two equal and opposite forces, a point is said to be in equilibrium. R. S. Ball, Exper. Mechanics, p. 6. 2. The state of balance of any causes, powers, or motives, so that no effect is produced. The balance is turned, and wherever this happens there is an end of the doubt or æquilibrium . Sharp, A Doubting Conscience. Enabled them eventually to restore the equilibrium which had been disturbed by the undue preponderance of the aristocrасу. Pre scott, Ferd. and Isa., i. 6. 3. A state of just poise; a position of due balance. Especially- (a) Mental balance. Only Shakespeare was endowed with that healthy equi librium of nature whose point of rest was midway between the imagination and the understanding. Lowell, Study Windows, p. 316. (b) In the fine arts: (1) The just poise or balance of a figure or other object, making it appear to stand firmly. (2) The properly balanced disposition or arrangement of objects, lights, shadows, etc. 4. Equality of influence or effect; due or just relationship. Health consists in the equilibrium between these two powers. Arbuthnot. Center of equilibrium. See center1. - Relative equilibrium, the instantaneous equilibrium of a particle; a situation from which a particle does not tend to move so long as other particles are held in their actual positions. Thus, a drop of water on the crest of a wave is in relative equilibrium. - Thermal equilibrium, such a distribution of heat within a gas subject to external forces (say the atmosphere) that no slow currents of its parts will alter the distribution of the heat in space. Thus, if the increase of pre ure due to bringing a portion of air from any height to the earth would increase its temperature just enough to bring that air to the temperature of the surrounding air, the atmosphere would be in thermal equilibrium. equilibrium-scale (e-kwi-libri-um-s if disturbed by any increase or diminution of the scale or balance for weighing so arranged that weight on the platform it will immediately return to a state of equilibrium or constant balance. It is used in recording the increase or lo of weight in living plants or animals, under varying circumstances of work or feeding, evaporation, etc. (e-kwi-lib'ri-um-skāl), n. A animals except cattle, and in man. The salient features of the disease are the formation of small tubercles, breaking down into ulcers, and the diffuse infiltration of large and irregular patches with a serous fluid containing numerous round cells. In addition, absce es of considerable size are formed, and the lymphatics become inflamed and swollen. These proce es go on for the most part in the cutaneous and subcutaneous ti ues, and in the mucous and submucous ti ues of the lungs and air pa ages, especially the nose. If the cutaneous symptoms are in abeyance while the mucous membrane of the nose is severely affected and the discharge profuse, the disease is called glanders; if the cutaneous symptoms are well developed while the discharge from the nose is insensible, it is called farcy. Each of these forms may be either acute or chronic. Equinia in man is in a majority of cases fatal. It seems to be caused by a bacillus of about the size of the tubercle-bacillus.
