Problem 5) A machine component is made of a low carbon steel with yield strength =200MPa and
ultimate strength =300MPa. It is loaded to point A on a stress-strain curve that has a stress =210MPa.
Next, the component is unloaded. Please draw the behavior of this material on a stress-strain curve.
Treating it as a new component, it is reloaded to point A again. What is the yield strength?
