| modulus | Origin: L, a small measure. See Module. <mathematics> A quantity or coefficient, or constant, which expresses the measure of some specified force, property, or quality, as of elasticity, strength, efficiency, etc.; a parameter. Modulus of a machine, a formula expressing the work which a given machine can perform under the conditions involved in its construction; the relation between the work done upon a machine by the moving power, and that yielded at the working points, either constantly, if its motion be uniform, or in the interval of time which it occupies in passing from any given velocity to the same velocity again, if its motion be variable; called also the efficiency of the machine. <mathematics> Modulus of a system of logarithms, a number by which all the Napierian logarithms must be multiplied to obtain the logarithms in another system. Modulus of elasticity. The measure of the elastic force of any substance, expressed by the ratio of a stress on a given unit of the substance to the accompanying distortion, or strain. An expression of the force (usually in terms of the height in feet or weight in pounds of a column of the same body) which would be necessary to elongate a prismatic body of a transverse section equal to a given unit, as a square inch or foot, to double, or to compress it to half, its original length, were that degree of elongation or compression possible, or within the limits of elasticity; called also Young's modulus. Modulus of rupture, the measure of the force necessary to break a given substance across, as a beam, expressed by eighteen times the load which is required to break a bar of one inch square, supported flatwise at two points one foot apart, and loaded in the middle between the points of support.

| modulus of elasticity | A coefficient expressing the ratio between stress per unit area acting to deform a body and the amount of deformation that results from it. Modulus of volume elasticity, a coefficient expressing the ratio between pressure acting to change the volume of a substance and the amount of change that results from it. Synonym: bulk modulus. Young's modulus, a type of modulus of elasticity which specifies the force applied to a body in one direction, per unit cross-sectional area of the body perpendicular to that direction, divided by the fractional change in length of the body in that direction.

| bulk | To appear or seem to be, as to bulk or extent; to swell. "The fame of Warburton possibly bulked larger for the moment." (Leslie Stephen) Origin: Bulked; Bulking. Source: Websters Dictionary (01 Mar 1998) |
| bulk density | Weight per unit of volume, usually specified in pounds per cubic foot. (05 Dec 1998) |
| radiation damage, bulk | <radiobiology> General term describing changes in chemical and/or metallurgical properties of structure components of fusion reactor caused by atomic displacement and nuclear transmutation events occuring as a result of exposure to a radiation environment (such as the neutrons emitted from a fission or D-T fusion reactor).
