Stainless steel springs are flexible and elastic but they are also known for their linear response.
A gym bar, on the other hand, may be made of the same material but it isn't as flexible as a spring.
In both cases, the mechanical response is close to a linear relationship. Such materials are best described using what is known as Hooke's law. In this section, this will be the focus of our discussion.
In this video, we will focus on Hooke's law and how it controls linear elasticity behavior.
Here are the accompanying handout slides for this lesson.
