Stress definition physics
Any definition of stress should therefore also include good stress, or what Selye called eustress. For example, winning a race or election can be just as stressful as losing, or more so. A passionate kiss and contemplating what might follow is stressful, but hardly the same as having a root canal procedure.How can the answer be improved? stress definition physics
stress (physics) force that produces strain on a physical body; the intensity of stress is expressed in units of force divided by units of area natural philosophy, physics the science of matter and energy and their interactions; his favorite subject was physics

Definition. Stress is defined as the force across a small boundary per unit area of that boundary, for all orientations of the boundary.
According to guidelines published by the American Physical Therapy Association, physical therapy should be defined as the examination, treatment, and instruction of persons in order to detect, assess, prevent, correct, alleviate, and limit physical disability and bodily malfunction.
Stress is a measure of the internal force an object is experiencing per unit cross sectional area: F A \displaystyle \sigma \frac FA Where is stress (in Newtons per square metre or, equivalently, Pascals), F is force (in Newtons, commonly abbreviated N),
The effects of stress are subtle and sometimes difficult to see. somebodys stress level (also somebodys level of stress) Exercise reduces stress levels. stresses and strains ( a lot of different worries that are caused by something) the stresses and strains of everyday life stress management Some patients may benefit from being taught
Stress: Stress, in physical sciences and engineering, force per unit area within materials that arises from externally applied forces, uneven heating, or permanent deformation and that permits an accurate description and prediction of elastic, plastic, and fluid behaviour.
Stress, on the other hand, has dimension of force per unit area, or, less often, force per unit length. This statement of Hookes Law (stress proportional to strain) is a more general statement than the more specific one given in a later slide, that restoring force is proportional to displacement.
Stress Formula We all come in touch with the word stress in our daytoday life when some external thing has an impact on our state of mind. Likewise in Physics, stress is the external restoring force acting on per unit area.
