  2. Stress and vowel reduction in English - Wikipedia

    en.wikipedia.org/wiki/Stress_and_vowel_reduction...

    Stress is a prominent feature of the English language, both at the level of the word (lexical stress) and at the level of the phrase or sentence (prosodic stress).Absence of stress on a syllable, or on a word in some cases, is frequently associated in English with vowel reduction – many such syllables are pronounced with a centralized vowel or with certain other vowels that are described as ...

    en.wikipedia.org/wiki/Stress_(linguistics)

    The stress placed on words within sentences is called sentence stress or prosodic stress. That is one of the three components of prosody , along with rhythm and intonation . It includes phrasal stress (the default emphasis of certain words within phrases or clauses ), and contrastive stress (used to highlight an item, a word or part of a word ...

    [9] [10] Chronic stress, and a lack of coping resources available, or used by an individual, can often lead to the development of psychological issues such as delusions, [11] depression and anxiety (see below for further information). [12] Chronic stress also causes brain atrophy, which is the loss of neurons and the connections between them ...

    The rhythm of the English language has four different elements: stress, time, pause, and pitch. Furthermore, "When stress is the basis of the metric pattern, we have poetry; when pitch is the pattern basis, we have rhythmic prose" (Weeks 11). Stress retraction is a popular example of phrasal prosody in everyday life. For example:

    (3) Example metrical grid The higher the column of Xs above a syllable, the more prominent the syllable is. The metrical grid and the metrical tree for a particular utterance are related in such a way that the Designated Terminal Element of an S node must be more prominent than the Designated Terminal Element of its sister W node.

    This type of stress may be called (simple) normal stress or uniaxial stress; specifically, (uniaxial, simple, etc.) tensile stress. [13] If the load is compression on the bar, rather than stretching it, the analysis is the same except that the force F and the stress σ {\displaystyle \sigma } change sign, and the stress is called compressive ...

  8. Stress relaxation - Wikipedia

    en.wikipedia.org/wiki/Stress_relaxation

    Experimentally, stress relaxation is determined by step strain experiments, i.e. by applying a sudden one-time strain and measuring the build-up and subsequent relaxation of stress in the material (see figure), in either extensional or shear rheology. a) Applied step strain and b) induced stress as functions of time for a viscoelastic material.

  9. Eustress - Wikipedia

    en.wikipedia.org/wiki/Eustress

    Hans Selye created the term as a subgroup of stress [3] to differentiate the wide variety of stressors and manifestations of stress. Eustress is not defined by the stress or type, but rather how one perceives that stressor (e.g., a negative threat versus a positive challenge). Eustress refers to a positive response one has to a stressor, which ...
