Hooke’s Law

Hooke’s law is a physical principle stating that the amount of force needed to extend a spring by a given distance scales linearly with respect to the distance.

That results in:

Fs = k⋅x

Fs is the applied force in [N]
k is the spring constant in [N/mm]
x is the deformation in [mm]


Relation to the elastic constants

Hooke’s law can be derived from the modulus of elasticity, E:



Simple harmonic oscillation
