Stress, emotional or psychological, is a degree of imbalance, inharmony or discord, in one's beliefs, comfort zone, ideas, personal, family, business or social interactions.
Stress (mechanics), the average amount of force exerted per unit area. It is the internal resistance a material offers to being deformed and is measured in terms of the applied load. The effects of mechanical stress on a polymer can be measured using dynamic mechanical analysis.
Compressive stress, the stress applied to materials resulting in their compaction. It is the ability of a material to resist being crushed.
Tensile stress (also referred to as tension) is the stress state leading to expansion.
Yield stress, the stress at which a material begins to deform plastically.
Harmony expressed by pulsations, ebb and flow, stress and accent
—Necessity of combining religious feeling with natural science in true music
—Remarks on the new College of Music, . . 50 [Harmonies of Tones and Colours, Table of Contents4 - Harmonies]
"Harmony must be looked at in two ways at least: first, up the score from bottom to top—the perpendicular view; second, along the score from side to side—the horizontal view. Then as to its periods or pulsations—its to and fro, its flow and ebb. This brings us to rhythm and measure. At the bottom of these lie what is called stress or accent—emission and remission—strong and weak: of these the bar in modern music is an outward and visible sign of certain facts which ought to be in the music, but which, if not in the music, the presence of the bar is of no avail. The bar cannot give stress or accent. 'Wherever there is time, there must be accent;'* but the tick of a clock has no accent. Hullah (or Chorley) should have said life." "The semitone makes music. What operation has it upon the accent or to and fro? It creates the call, it supplies the answer." [This point, I believe, Dr. Gauntlett never alluded to with me, and I have feared that making no difference between tones and semitones might be considered a difficulty with regard to the scheme. In the working of the natural laws of harmony, they must all equally be employed.—F. J. H.] "Art (grand and true) does not depend upon the teaching of facts. The head is of less importance than the heart. Unless the tone of feeling, the habit and disposition, be well fixed, nothing enduring can come out of the misdirected artist." [Harmonies of Tones and Colours, Fragments from the Last Note-book, page 50]

"What this method of 'meditating' will achieve for you will be a relief from the thoughts and stress that your ego pressures are creating for you. In the world of imagination, the ego may - or may not - be dormant." [Christ Letters - Letter 8, page 24]
"It [laughter] is a ripple effect experienced in all living things of higher species capable of certain judgments or perceptions. It eliminates stress. The 'ripple effect' is felt over the diaphragm which guards the heart and nervous system.
As you have seen on examining the nature of creation, everything possible has been done in the evolution of design and growth of living bodies to make a perfectly adapted body to suit the environment to enable the occupier of the body to be comfortable and happy and live without stress. Stress is inimical to health.
It is contrary to the WILL of DIVINE CONSCIOUSNESS." [Christ Returns - Speaks His Truth, Letter 9, page 14]
