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 ...
9 de abr. de 2024 · 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.
La ley de Hooke: la tensión es proporcional a la elongación axial de la pieza. En física, la ley de elasticidad de Hooke o ley de Hooke 1 establece que el alargamiento unitario que experimenta un cuerpo elástico es directamente proporcional a la fuerza aplicada sobre el mismo ( ): Siendo ( ) el alargamiento, ( ) la longitud original ...
Hooke's law. When studying springs and elasticity, the 17ᵗʰ century physicist Robert Hooke noticed that the stress vs strain curve for many materials has a linear region. 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.
Materials for which Hooke’s law is a useful approximation are known as linear-elastic or “Hookean” materials. Hookean materials are broadly defined and include springs as well as muscular layers of the heart. In simple terms, Hooke’s law says that stress is directly proportional to strain.
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.
Now let us apply Hooke’s law, in the form of Eqs. (32) or (34), to two simple situations in which the strain and stress tensors may be found without using the full differential equation of the elasticity theory and boundary conditions for them.
