Question

The intensity of stress which causes unit strain is called

• A. Unit stress
• B. Bulk modulus
• C. Modulus of rigidity
• D. Modulus of elasticity

Answer 1

Answer:

D. Modulus of elasticity

The stress that causes unit strain is known as Modulus of Elasticity (E), which is the ratio of tensile or compressive stress to the corresponding strain. It is also called Young's Modulus and denoted by E = σ /e where σ is tensile or compressive stress and e is strain.
