The point at which a stress of a material exhibits a specific limited deviation P is called_______________?
Correct answer: A. Yield strength
- A. Yield strength
- B. Tensile strength
- C. Ultimate strength
- D. Proportional limit
Explanation
Yield strength is defined using a specified small permanent strain, commonly 0.2%, rather than complete fracture. The proportional limit instead marks the end of the strictly linear stress-strain relationship.
