Modulus of elasticity means_______________?
Correct answer: B. Rigidity or stiffness of the material
- A. Ability to be stretched with permanent deformation
- B. Rigidity or stiffness of the material
- C. Ductility of a material
- D. Malleability of the metal
Explanation
The modulus of elasticity is the stress-to-strain ratio in the elastic range and indicates how stiff or rigid a material is. A high modulus means greater resistance to elastic deformation.
