What Does Potential Energy of Loading Mean in the Context of Spring Energy?

Click For Summary
SUMMARY

The discussion centers on the equation for the potential energy of an elastic body, specifically a spring, defined as the difference between strain energy and potential energy of loading. The strain energy is quantified as 0.5*k*x², where k represents the spring constant and x denotes displacement. The term "potential energy of loading" is explored, suggesting it relates to non-conservative forces such as plastic deformation or friction. This distinction is crucial for understanding energy storage in elastic materials.

The following equation i came across when i was studying the minimum potential energy principle

QUOTE:
POTENTIAL ENERGY OF AN ELASTIC BODY(example spring)=STRAIN ENERGY-POTENTIAL ENERGY OF LOADING

We all know that the strain energy of a spring is equal to 0.5*k*x*x were x is the displacement in the spring and k is the spring constant. This is called STRAIN ENERGY.

What is the second term "POTENTIAL ENERGY OF LOADING" mean.

Only mass and elastic bodies can store energy. Why LOADING has POTENTIAL ENERGY?
