Elastic has nothing to do with your underwear, and plastic has nothing to do with polymer parts, both have a lot to do with paper clips and mag springs.
In my mechanical engineering curriculum, Electrical Circuits was a 2 semester agony. Spring Theory and Elastic Deformation was 4 weeks of severe pain.
I will continue my walk away.

That is why the paper clip analogy is erroneous; mag springs are operating elastically below yield stress BUT deform due to creep; bent paper clip stress is above yield resulting in plastic deformation and probable fracture. How can anyone not like Electrical Circuits?!?
