In a tensile test, if a material exhibits a linear stress-strain relationship, what type of deformation is it undergoing?
Correct Answer: Elastic Deformation
- Step 1: Understand what a tensile test is. It is a method to measure how a material reacts to being pulled apart.
- Step 2: Learn about stress and strain. Stress is the force applied to the material, and strain is how much the material deforms.
- Step 3: Recognize that a linear stress-strain relationship means that as you increase the stress, the strain increases in a straight line.
- Step 4: Identify the type of deformation. A linear relationship indicates that the material returns to its original shape after the stress is removed.
- Step 5: Conclude that this type of deformation is called elastic deformation.
