Hooke’s law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load. Under these conditions the object returns to its original shape and size upon removal ...
Feb 12, 2024 · 胡克定律 （英语： Hooke's law ）是 力学 的 弹性理论 中的一条基本 定律 ，指固体 材料 受 力 后， 应力 与 应变 （单位变形量）成 线性关系 ，满足此定律的材料称为线弹性或胡克型材料。. 从 物理学 的角度看，胡克定律源于多数固体（或孤立 分子 ）内部的 ...
In 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 ...
Within certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring. This is known as Hooke's law and commonly written:
Springs and Hooke’s Law: A brief overview of springs, Hooke’s Law, and elastic potential energy for algebra-based physics students. Many materials obey this law of elasticity as long as the load does not exceed the material’s elastic limit.
Feb 16, 2015 · Hooke's Law is a principle of physics that states that the force needed to extend or compress a spring by some distance is proportional to that distance. The law is named after 17th...
Jun 2, 2024 · Hooke’s Law is the governing principle behind a material’s behavior when subjected to deforming forces. It is applicable within the elastic limits of a material and states that the strain or deformation of a material is directly proportional to the deforming force or stress applied to it.
Feb 20, 2022 · Explain Newton’s third law of motion with respect to stress and deformation. Describe the restoration of force and displacement. Calculate the energy in Hook’s Law of deformation, and the stored energy in a string. Newton’s first law implies that an object oscillating back and forth is experiencing forces.
The simplest oscillations occur when the restoring force is directly proportional to displacement. When stress and strain were covered in Newton’s Third Law of Motion, the name was given to this relationship between force and displacement was Hooke’s law:
In elementary mechanics the elasticity of a spring is expressed by Hooke’s law which says that the amount a spring is stretched or compressed beyond its relaxed length is proportional to the force acting on it. In continuous elastic materials Hooke’s law implies that strain is a linear function of stress.
