How does force affect stress?
Derived from a fundamental physical quantity (force) and a purely geometrical quantity (area), stress is also a fundamental quantity, like velocity, torque or energy, that can be quantified and analyzed without explicit consideration of the nature of the material or of its physical causes.

Stress is the force per unit area on a body that tends to cause it to change shape. [2] Stress is a measure of the internal forces in a body between its particles. [2] These internal forces are a reaction to the external forces applied on the body that cause it to separate, compress or slide. [2]
Summarize this article for a 10 year old. SHOW ALL QUESTIONS. In continuum mechanics, stress is a physical quantity that describes forces present during deformation. For example, an object being pulled apart, such as a stretched elastic band, is subject to tensile stress and may undergo elongation. An object being pushed together, such as a ...
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. A stress is expressed as a quotient of a force divided by an area.

Jun 14, 2023 · Stress is a quantity that describes the magnitude of forces that cause deformation. Stress is generally defined as force per unit area. When forces pull on an object and cause its elongation, like the stretching of an elastic band, we call such stress a tensile stress. When forces cause a compression of an object, we call it a compressive stress.
