Hooke's law

I can take a spring like this one and stretch it to the point that it no longer behaves like Hooke's Law.

Hooke' s law postulates that the material has linear elastic behavior and we do not intend considering a different material.

That's a requirement, of course, for an ideal spring if it behaves according to Hooke's Law.

For an elastic material, Hooke's Law states. that the ratio of strain to stress is constant.

Newton's law of gravity; Gravitational force from a shell; Hooke's 'law'.

In other words, we abandon Hooke's Law, as I will show you also today with a demonstration.

Michel: Ever hear of tensile strength? Hooke's Law of Elasticity?

Whenever this linear relation between F and x holds, that is referred to as Hooke's Law.

For sure, Hooke's Law is no longer active.

Ever hear of tensile strength? Hooke's law of elasticity?

The elasticity of solid obey Hooke's Law, wood vertical force when the stress and strain in the ratio limit is obeyed Hooke's Law.

So the wire, when it reaches the end of its Hooke's Law parameter space, 13% has only become longer by 0. 13%.

So Hooke's Law holds only within certain limitations.

With purely elastic deformation the strain is a linear function of stress, that is , the material obeys Hooke's law.

Ideal case means Hooke's Law must hold.

Nothing new, as long as Hooke's Law holds.

It obeys Hooke's Law, and it is also nearly massless.
