Elastic Potential Energy - Stretching of a spring

What is energy with elastic potential?

Elastic potential energy is the energy stored in compressed or stretched objects, elastic potential energy is used in calculations of mechanical equilibrium.

The energy accumulated as a result of applying a force to bend the elastic material is elastic potential energy.

Until the force is extracted, the energy is retained and the

object springs back to its original form, doing work in the process.

Compressing, bending or rotating the material

could be involved in the deformation.

For example, several objects are explicitly designed to store elastic potential energy, such as:

A wind-up clock's coil spring

The extended bow of an archer

Right before the diver’s leap, a bent diving board

 The twisted band of rubber powering a plastic airplane

 A bouncy ball, compressed off a brick wall at the time it bounces.

 There would usually be a high elastic limit for an object built to hold elastic

potential energy, but all elastic structures have a limit to the load they will bear.

The material can no longer revert to its original shape when deformed past the elastic limit.

In earlier years, coil springs were operated by wind-up mechanical watches p p

 

What about the real materials of elasticity?

 In our article on the law and elasticity of Hooke, we discuss how actual

springs only follow the law of Hooke over a specific spectrum of applied force.

Some elastic materials can act as springs, such as rubber bands and flexible plastics, but also have hysteresis; this suggests that the force vs extension curve takes a different direction when the material is deformed relative to when it relaxes back to its place of equilibrium.

 Fortunately, the simple technique of applying for the job description we used

for an ideal spring still works in general for elastic materials.

The elastic potential energy, irrespective of the form of the curve, can

still be found from the field under the force vs. the extension curve.

 We treated the ideal spring as a one-dimensional entity in our earlier research. Elastic materials are in fact, three-dimensional.

The same method still works, it turns out. Stress is the inverse of the force vs. extension curve
