What is stress?
Stress is a real physical quantity in continuum mechanics. It is a measure of the strength of the forces that cause deformation. Force per unit area is the definition of stress.
Tensile stress is created when an object is pulled apart by a force, causing elongation, which is also referred to as deformation and is similar to how an elastic band stretches. Compressive stress, on the other hand, is what happens when forces cause an object to compress.
It happens when a body is subjected to forces like compression or tension. The stress increases as the force increases and as the body's cross-sectional area that it acts on decreases. As a result, stress is expressed as newton per square meter (N/m2) or pascal (Pa).
