[online] Available at: WebOct 19, 2024 · The material which obeys Hooke's law is called Hookean materials. Two materials that do not obey Hooke's law are rubber, plastic. This is so because every substance has an elasticity with an elastic limit. Hooke’s Law states that, for certain elastic materials, force is directly depends on extension, when a sample (substance) is stretched. crayford mini

"WebYoung's modulus can be defined at any strain, but where Hooke's law is obeyed it is a constant. We can directly obtain the spring constant k k from the Young's modulus of the material, the area A A over which the force is applied (since stress depends on the area) and nominal length of the material L L.

WebDo brittle materials plastically deform? No They obey Hooke’s law and then snap when the force/stress becomes too great. What is the structure of brittle materials? Crystalline or polycrystalline The atoms in each crystalline region line up in a different direction and bonded in a giant rigid structure 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.

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 …

WebJul 22, 2024 · when materials are compressed or extended under force, their atoms become closer or further apart; electrostatic forces (and indeed most other forces) follow an inverse-square law; So I would naively conclude that springs should follow an inverse square law.
