Question

Define hooks law ...​

Answer 1

$\huge\frak\pink{Answer}$

Hooke's law is a law of physics that states that the force needed to extend or compress a spring by some distance scales linearly with respect to that distance—that is, Fₛ = kx, where k is a constant factor characteristic of the spring, and x is small compared to the total possible deformation of the spring.

Answer 2

Answer:

with in elastic limit the stress is directly proportional to the stress stress/strain =E ' E ' is a constant called modules of elasticity. the dimensional formula of modules of elasticity is ML-1T-2. its units Nm-2
