Questions & Step-by-Step Solutions
In a tensile test, if the stress-strain curve of a material shows a linear relationship, what does this indicate?
Step 1: Understand what a tensile test is. It is a test to see how a material reacts when pulled apart.
Step 2: Know that stress is the force applied to the material, and strain is how much the material deforms.
Step 3: Look at the stress-strain curve, which is a graph showing the relationship between stress and strain.
Step 4: Identify what a linear relationship means. It means that as stress increases, strain increases in a straight line.
Step 5: Realize that a linear relationship indicates that the material is behaving elastically. This means it will return to its original shape when the stress is removed.
