Details of Elastic Body, Elasticity, Limit of Elasticity & Hooke's Law:

Elasticity refers to the property of materials that allows them to return to their original shape and size when the force that deformed them is removed. An elastic body is a material that can undergo deformation when a force is applied to it, but it can also return to its original shape and size when the force is removed. Elasticity is an important property of materials used in various engineering applications.

Hooke's Law is a fundamental principle of elasticity that states that the deformation of an elastic body is proportional to the applied force, as long as the limit of elasticity is not exceeded. Hooke's Law can be expressed mathematically as:

F = kx

Where F is the force applied to the elastic body, x is the deformation caused by the force, and k is a constant of proportionality known as the spring constant. The spring constant depends on the material properties of the elastic body, such as its Young's modulus, and the geometry of the body.

The limit of elasticity, also known as the elastic limit, is the maximum stress that an elastic body can withstand without undergoing permanent deformation. Beyond the limit of elasticity, the material will undergo plastic deformation, meaning that it will be permanently deformed even after the applied force is removed.

In summary, elasticity is the property of materials that allows them to return to their original shape and size when the force that deformed them is removed. An elastic body can undergo deformation and return to its original shape when the force is removed, as long as the limit of elasticity is not exceeded. Hooke's Law is a fundamental principle of elasticity that describes the relationship between the force applied to an elastic body and its deformation.
