In the language of physics, two terms describe the forces on objects undergoing deformation: stress and strain. Stress is a quantity that describes the magnitude of forces that cause deformation. Stress is generally defined as force per unit area.
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.
Bones are brittle and the elastic region is small and the fracture abrupt. Eventually a large enough stress to the material will cause it to break or fracture. Tensile strength is the breaking stress that will cause permanent deformation or fracture of a material.
The ratio of force to area, \(\frac{F}{A} \) is defined as stress (measured in \(N/m^2q\), and the ratio of the change in length to length, \(\frac{\Delta L}{L_0} \) is defined as strain (a unitless quantity). In other words,
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.
What is stress in physics? Stress is the force acting on the unit area of a material. Learn about its definition, formula, units, types - longitudinal stress, bulk stress, shear stress along with practice questions.
