Denotes the value of the stress ratio (load divided by area) to the strain (such as elongation) of a material It is a measure of the relative flexibility and resilience of a material (i e , rubber has a low modulus and steel a high one) Modulus is expressed in psi
(1) A coefficient or numerical measure of some property (2) In polymers, modulus usually refers to one of several measurements of stiffness or resistance to deformation The use of the word without modifying terms may be confusing and such use should not be encouraged Modulus in polyurethane may be either static or dynamic; static moduli are subdivided into tangent, chord, and compounder's Compounder's modulus is always in tension, but all the others may be in shear, compression or tension Other terms used in connection with "modulus" are elasticity, rigidity, Young's tangent, and elongation (3) All elastic moduli in rubber (except compounder's) are ratios of stress to the strain produced by that stress, the stress, usually p s i
Measure of the ratio of applied load (stress) to the resultant deformation of a material, such as elasticity of shear Can be low, intermediate, high of ultrahigh
Used to refer to a measure of some physical or mechanical property of a material The modulus is generally constant for any material, and can be used to calculate a material's response to external conditions, such as applied forces One common example is Young's Modulus, which expresses the elastic response of a meterial
a quanity that expresses the degree to which a substance possesses a property, such as elasticity or stiffness; high modulus indicates a stiff fiber, while low modulus indicates a more elastic fiber MOMENT OF INERTIA (MOI): refers to the ability of a clubhead to resist twisting at impact on off-center hits; a low MOI will twist more than a high MOI at impact; oversize clubheads increase MOI and thus reduce twisting MULTI-COVER BALL: a golf ball which contains two covers
(physics) a coefficient that expresses how much of a specified property is possessed by a specified substance the absolute value of a complex number an integer that can be divided without remainder into the difference between two other integers; "2 is a modulus of 5 and 9
A quantity or coefficient, or constant, which expresses the measure of some specified force, property, or quality, as of elasticity, strength, efficiency, etc
{i} (Mathematics) number by which one can multiply logarithms of one system to obtain the logarithms of another system; number by which two quantities can be divided to yield the same remainder
a measure of the ability of a fibre to resist extension Normally measured as the ratio of the stress (or load) applied on a yarn or filament to the elongation (strain) resulting from the application of that stress
This is a measure that tries to explain how a fabric reacts when it tensioned and relaxed It is used to expain things like snow and wind loads, elasticity, memory, stretch, and shrinkage
A unit of measure For example, when measuring days, a modulus could be 24 for the number of hours in a day 75 hours would be divided by 24 to give 3 remainder 3, or 3 days and 3 hours See also modular arithmetic (cf Clocks and Modular Arithmetic Discussion)
