Engineering elasticity, also known as mechanical elasticity, is the ability of a material or structure to return to its original shape and size after it has been subjected to a deforming force or strain. It is an important property for many engineering materials, as it is necessary for the material or structure to withstand stresses and strains without permanent deformation or damage.

Engineering elasticity can be demonstrated through the use of a spring. When a spring is subjected to a force, the coils will compress, creating a strain on the spring. As the force is removed, the coils will gradually return to their original shape and size. This is because of the material's elasticity; the material has the ability to store energy when it is stretched, and then release the energy as it returns to its original shape.

The material's ability to stretch and return to its original shape and size is also what determines its ability to withstand various types of stress and load. For example, an elastic material will be able to absorb shocks, whereas a non-elastic material will not. This is why it is important for engineering materials to have a certain amount of engineering elasticity; it allows them to withstand the stresses and loads that they may be subjected to in their intended application.

The engineering elasticity of a material can be determined in a laboratory through the use of a tensile or compression test. This test will measure the strain and force required to deform the material, and can be used to calculate its Young's modulus, which is a measure of the material's elasticity.

Engineers use engineering elasticity to design and construct materials that can safely withstand a variety of stresses and loads. They use the material's elasticity to calculate the amount of stress or load that the material can safely take before it begins to deform or fail. As such, engineering elasticity is a very important consideration when designing and constructing any structure or material.
