For example, an object being pulled apart, such as a stretched elastic band, is subject to tensile stress and may undergo elongation. Stress is proportional to load and strain is proportional to deformation as expressed with hooke's law E = stress / strain = (fn / a) / (dl / lo) (4) where E = young's modulus (n/m2) (lb/in2, psi) Stress and strain are fundamental concepts in engineering, and in strength of materials in particular, that describe how an object responds to applied loads
This page covers the basics, which are also summarised in the following video: In mechanical engineering, stress is defined as the internal resistance offered by a material per unit area when subjected to an external force It is a key factor in analyzing how materials behave under load The mathematical formula for stress is Stress = force / area. Includes stress equations and examples.
It quantifies how intensely a material experiences force and helps predict failure under various loading conditions. Learn about engineering stress, its significance, and methods used in analysis for solving engineering challenges. It covers essential concepts such as elastic and plastic behavior, toughness, and strain hardening
