| equivalent temperature | The temperature of a thermally uniform enclosure in which, under still air conditions, a "sizable" black body loses heat at the same rate as in the nonuniform environment. (05 Mar 2000) |
| equivalent weight | The weight in grams of an element that combines with or replaces 1 gram of hydrogen, the atomic or molecular weight in grams of an atom or group of atoms involved in a chemical reaction divided by the number of electrons donated, taken up, or shared by the atom or group of atoms in the course of that reaction, the weight of a substance contained in 1 liter of 1 normal solution; a variant of. Synonym: combining weight, equivalent weight. (05 Mar 2000) |
| Joule's equivalent | The dynamic equivalent of heat; the amount of work converted to heat that will raise the temperature of 1 pound of water 1캟 is 778 foot-pounds; in metric units, 1 calorie, which raises 1 gram of water 1캜, equals 4.184 × 107 dyne-centimeters, which equals 4.184 joules. (05 Mar 2000) |
| lethal equivalent | A combination of selective effects that on average have the same impact on the composition of the gene pool as one death; e.g., two carriers at 50% risk of dying would be the lethal equivalent of one carrier at 100% risk, in the population genetics of recessive traits lethal equivalent is expressed as twice the sum of the expected number of deaths ascribable to the genetic load. Expression used of the genetic load of recessive genes in heterozygous state that if in homozygous state would cause death or carry a risk of death. The expected number of deaths from all such genes is expressed in lethal equivalent. (05 Mar 2000) |

| mechanical | 1. Pertaining to, governed by, or in accordance with, mechanics, or the laws of motion; pertaining to the quantitative relations of force and matter, as distinguished from mental, vital, chemical, etc.; as, mechanical principles; a mechanical theory; mechanical deposits. 2. Of or pertaining to a machine or to machinery or tools; made or formed by a machine or with tools; as, mechanical precision; mechanical products. "We have also divers mechanical arts." (Bacon) 3. Done as if by a machine; uninfluenced by will or emotion; proceeding automatically, or by habit, without special intention or reflection; as, mechanical singing; mechanical verses; mechanical service. 4. Made and operated by interaction of forces without a directing intelligence; as, a mechanical universe. 5. Obtained by trial, by measurements, etc.; approximate; empirical. See the 2d Note under Geometric. Mechanical effect, effective power; useful work exerted, as by a machine, in a definite time. Mechanical engineering. See the Note under Engineering. Mechanical manoeuvres, the application of mechanical appliances to the mounting, dismounting, and moving of artillery. Mechanical philosophy, the principles of mechanics applied to the inverstigation of physical phenomena. Mechanical powers, certain simple instruments, such as the lever and its modifications (the wheel and axle and the pulley), the inclined plane with its modifications (the screw and the wedge), which convert a small force acting throught a great space into a great force acting through a small space, or vice versa, and are used separately or in combination. <mathematics> Mechanical solution, a solution of a problem by any art or contrivance not strictly geometrical, as by means of the ruler and compasses, or other instruments. Origin: From Mechanic. Source: Websters Dictionary (01 Mar 1998) |
