Yes, in theory. But it is only valid up to a certain point of stress, after which the molecular bonds starts to break down. In reality, some materials are so difficult to stretch (so brittle) that it is almost impossible to apply Hooke's law to them. (Our school teacher use to say: dunk a biscuit into tea and then try to stretch it)
all of them
Its all to do with Hookes law................
Hello jack cena
Hooke's law of Elasticity.
No, not every material is valid for Hooke's Law. Hooke's Law is specifically valid for linearly elastic materials, which exhibit a linear relationship between stress and strain. Materials that do not exhibit linear elasticity, such as plastics or rubber, do not follow Hooke's Law.
Hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it.
Hooke's Law relates to the elasticity of elastic objects, such as metal springs, and how they stretch in proportion to the force that acts on them.
Hooke's law describes the relationship between the force applied to a spring and the resulting extension or compression of the spring, as long as the material remains in the elastic deformation range of the stress-strain curve. Beyond the elastic limit, the material may exhibit plastic deformation, and Hooke's law may not apply.
No, by definition Hooke's law relates to linear elastic only; when outside the elastic region it does not apply.
It's valid.
Ohm's Law is valid for constant temperature because it assumes a fixed relationship between voltage, current, and resistance. Any changes in temperature can alter the resistance of the material, affecting the accuracy of the law. Additionally, Ohm's Law is only valid for constant pressure because pressure changes can affect the physical properties of the material, such as its conductivity, which can also impact the law's accuracy.
Material alteration refers to a significant change made to a contract that affects its terms or conditions. In contract law, a material alteration can render the contract void or unenforceable if it is made without the consent of all parties involved. This means that any changes to a contract that are considered important or substantial must be agreed upon by all parties for the contract to remain valid.
