Materials like … WebWires obey Hooke’s law, just like springs do. When a force F is applied, it will extend some distance x, which can simply be described by the equation F = kx Whereas k for a spring is the spring constant, the amount of extension for a wire depends on its cross sectional area, length, and the material it is made from.

WebSep 2, 2024 · In the early (low strain) portion of the curve, many materials obey Hooke’s law to a reasonable approximation, so that stress is proportional to strain with the constant of proportionality being the modulus of elasticity or Young’s modulus, denoted \(E\): \[\sigma_e = E_{\epsilon_e}\] WebHOOKE’S LAW Hookes Law states that the stretch of an elastic material is directly proportional to the applied force. Hookes Law is valid for a material as long as the …

WebIn physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. The law is named after … WebA material obeys Hooke’s Law if: The extension of the material is directly proportional to the applied force (load) up to the limit of proportionality This linear relationship is represented by the Hooke’s law equation: F = kΔL Where: F = force (N) k = spring constant (N m –1) Δ L = extension (m)
