Strain energy is the energy stored in a body when strained within elastic limits. This means that when a material is deformed, it stores energy within itself. The energy is stored in the form of potential energy, which can be released when the material returns to its original shape.

Explanation of the answer:

• Elastic limits: Strain energy is only stored within the elastic limits of a material. Beyond this limit, the material will undergo permanent deformation and may even break.

• Energy stored: When a material is deformed, its molecules are stretched or compressed, and potential energy is stored within it. This energy is proportional to the amount of deformation and the stiffness of the material.

• Release of energy: When the deforming force is removed, the material returns to its original shape and the stored energy is released. This can be seen in situations like the bouncing of a ball or the release of energy from a compressed spring.

• Importance: Strain energy is an important concept in engineering, as it affects the behavior of materials under stress and strain. Understanding how much strain energy a material can store is crucial in designing structures and machines that can withstand the loads they will be subjected to.

In conclusion, strain energy is the energy stored in a material when it is deformed within its elastic limits. It is an important concept in engineering and affects the behavior of materials under stress and strain.
