The units of Young's modulus of elasticity and ________________ are the same?
Correct answer: B. Stress
- A. Strain
- B. Stress
- C. Modular ratio
- D. None of these
Explanation
Young's modulus is stress divided by strain; since strain is dimensionless, its units are the same as stress, such as Pa or N/m². The modular ratio is dimensionless and cannot have the same units.
