The modulus of elasticity is defined as_______________?
Correct answer: D. The stress/strain ratio within the proportional limit
- A. The stress at the proportional limit
- B. The strain at the proportional limit
- C. None of the above
- D. The stress/strain ratio within the proportional limit
Explanation
Within the proportional limit, modulus of elasticity equals stress divided by strain, represented by the slope of the straight portion of the stress-strain curve. It is a measure of stiffness, not the stress or strain value alone.
