Question

what is hook's law?

Accepted Answer

Hook's law states that the extension of a spring is directly proportional to the force applied to it.

It is a principle of physics that describes the relationship between the force applied to a spring and the distance it stretches or compresses.
The law is named after Robert Hooke, an English physicist who first formulated it in the 17th century.
The law is expressed mathematically as F = kx, where F is the force applied, x is the displacement of the spring from its equilibrium position, and k is the spring constant.
The law applies to any elastic material, not just springs. For example, it can be used to describe the behavior of rubber bands, bungee cords, and other elastic materials.
The law is important in many areas of engineering, including mechanical, civil, and aerospace engineering.
