Hooke's law - Wikipedia

Hooke's law is a principle of physics that 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: =, where k is a constant factor characteristic of the spring: its stiffness, and x is small compared to the total possible deformation of the spring. The law is named after 17th-century British physicist Robert Hooke.Formal definition·

constant force springs A constant force , or "clock" spring, is a roll of prestressed strip which exerts a nearly constant restraining force to resist uncoiling. The force is constant because the change in the radius of curvature is constant.

Constant-force spring - Wikipedia

An ideal constant-force spring is a spring for which the force it exerts over its range of motion is a constant, that is, it does not obey Hooke's law. In reality, "constant-force springs" do not provide a truly constant force and are constructed from materials which do obey Hooke's law.

How to Calculate a Spring Constant Using Hooke’s Law

Constant Force Springs - Mounting - Spring-I-Pedia

Constant force springs mounted back-to-back make the sum of their forces available at one point. This method also provides stable extension over long deflections. Tandem mounting makes the sum of two spring forces available at a single point but does not add stability.

Constant Force Spring Design and Equations - Engineers Edge

A constant-force spring is a spring for which the force it exerts over its range of motion is a constant. That is, it does not obey Hooke's law. Generally constant-force springs are constructed as a rolled ribbon of spring steel such that the spring is relaxed when it is fully rolled up.
