stress is a tool to impose load on and stress test Unix-like systems. It will impose user-specified amounts of CPU, I/O, RAM, and HDD load and report any errors it detects. It is used for automated stress testing and for debugging system components which fail only or more often when under load. It runs on x86, PPC64, and PPC 32 GNU/Linux, Tru64, SPARC Solaris, and more.
Pressure, strain; -- used chiefly of immaterial things; except in mechanics; hence, urgency; importance; weight; significance.
The force, or combination of forces, which produces a strain; force exerted in any direction or manner between contiguous bodies, or parts of bodies, and taking specific names according to its direction, or mode of action, as thrust or pressure, pull or tension, shear or tangential stress.
Force of utterance expended upon words or syllables. Stress is in English the chief element in accent and is one of the most important in emphasis. See Guide to pronunciation, §§ 31-35.

In general terms, stress is any attempt to deform a solid. Types of stress include tension, compression, and shear. More specifically, stress is the ratio of force to unit area, /, where is force and area. Thus, it is similar to pressure, and indeed, compression is a form of pressure.

Force applied to a material that tends to change its dimensions or volume; force per unit area.
Force or load per unit area, often thought of as force acting through a small area within a plane. Can be divided into normal, perpendicular to the surface, and shear, parallel to the surface, components. True stress denotes the stress where force and area are measured at the same time. Conventional stress, as applied to tension and compression tests, is force divided by original area. Nominal stress, ignoring stress raisers and disregarding plastic flow, in a notch bend test, for example, it is bending moment divided by minimum section modulus.

Load on a specimen divided by the area through which it acts. As used with most mechanical tests, stress is based on original cross-sectional area without taking into account changes in area due to applied load. This sometimes is called conventional or engineering stress. True stress is equal to the load divided by the instantaneous cross-sectional area through which it acts.

Words of three or more syllables may have secondary stress on one of the remaining syllables: photograph, ' responsibility.It may also refer to the greater emphasis of some syllables or words over others in speech.

Force per unit area acting on a plane within a body. Six values are required to characterize completely the stress at a point: three normal components and three shear components.
Physics has a strict definition of 'a force per unit area' and producing 'strain' in the body to which the force is applied. Biology has a wide variety of meanings, e.g. any condition that results in reduced growth, any condition that prevents an organism from realizing its 'genetic potential'. The word is often redundant, e.g. the effects of drought stress/the effects of drought. The word is also often used confusingly in two senses, both to describe force and the condition induced in the organism by the force - a confusion of stimulus and response. We have tried not to use the word.

In linguistics, stress is the relative emphasis that may be given to certain syllables in a word. The term is also used for similar patterns of phonetic prominence inside syllables.
Stress is the internal distribution of force per unit area that balances and reacts to external loads applied to a body. It is a second-order tensor with nine components, but can be fully described with six components due to symmetry in the absence of body moments. Stress is often broken down into its shear and normal components as these have unique physical significance.
