Which Stress vs Strain Curve Has a Larger Slope?

Click For Summary
To determine which stress vs. strain curve has a larger slope, one must compare the steepness of the curves, assuming identical scaling on both axes. Without proper scaling, accurately assessing slopes is impossible. The discussion also highlights that "set strain" refers to permanent deformation, while "necking" occurs when a material begins to thin at its weakest point during stress application. The stress may decrease after a certain point due to the engineering stress being calculated based on the original cross-sectional area, not the reduced area during necking. Understanding these concepts is crucial for interpreting stress-strain behavior in materials.

Sir @Bystander I again want to start conversation with you,can I?
If the question is on-topic, so stress/strain relationship, just ask the question and either Bystander or somebody else will be able to help you. If the question is about something else, then please start another topic.
