Stress and strain. In this video let's explore what these are and why we define them?

In this video, we will explore the regions beyond the elastic limits. We will take a steel rod and keep stressing it until it breaks. We will draw a graph of stress vs strain and explore all the different regions of it.  Mahesh Shenoy video https://cdn.kastatic.org/googleusercontent/d48iB8aFNlb7DFFvKB7dxSSa_qWv9HXsXAwffNYbqjnTp5lA4o59xbu2yfjyrvysJjPirGum47BsCDN96mpc7fFIKw Stress vs strain curve What happens if you stretch something beyond its elastic limits?
