stress

stress: stress n 1 Stress, strain, pressure, tension are comparable terms when they apply to the action or effect of force exerted within or upon a thing. Stress and strain are the comprehensive terms of this group and are sometimes used interchangeably

{
put stresses and strains on parts of the body that were not constructed to bear that burden— Fishbein
}

{
if sufficiently large stresses are applied to any crystal, it remains at least partly deformed when the stresses are removed— Seitz
}

{
the wrench is an instrument for exerting a twisting strain, as in turning bolts and nuts— Burghardt & Axelrod
}

{
by a powerful strain upon the reins, raising his horse's forefeet from the ground—De Quincey
}

{
the breakup due to tremendous strains experienced in bad weather have time and again proven the fatal power of squalls over dirigibles— Furnas
}

Although stress is frequently used in technical contexts in the above sense of a force applied to deform a body, it is also used, especially in physics, of the equal and opposite forces with which the body resists being deformed

{
a weight suspended from a rod tends to pull the rod apart. The stress developed in the rod to resist being pulled apart is called tensile stress— Samuel Slade & Louis Margolis
}

Strain in technical contexts and especially in physics usually denotes the deformation of a body as a result of applied force

{
a new device . . . conveniently measures strain in vulcanized rubber . . . after application of a predetermined stress— Technical News Bulletin
}

{
it is generally held that most earthquakes are caused by the sudden release of elastic strain when this becomes greater than the strength of the rock— Science
}

Pressure commonly applies to a stress which is characterized by a weighing down upon or a pushing against a surface and which, in fluids, is distributed uniformly in all directions; it is usually measurable per unit area of surface affected

{
the normal atmospheric pressure is about 14.7 pounds per square inch—Kan Nostrand's
}

{
the pressure of the blood against the walls of blood vessels
}

{
steam pressure
}

Tension applies to either of two balancing forces causing or tending to cause elongation of an elastic body or to the stress resulting from the elongation of such a body

{
a steel bar can safely bear a pull or tension of 16,000 lb. for each square inch of its cross section— Samuel Slade & Louis Margolis
}
