MCQ
The modulus of elasticity is dimensionally equivalent to
- ASurface tension
- ✓Stress
- CStrain
- DNone of these
✓
Answer
Correct option: B.
Stress
b
(b) Hookes law establishes the relationship between stress and strain
(b) Hookes law establishes the relationship between stress and strain
Stress$:$ The force per unit area
Strain$:$ The elongation or contraction per unit length (dimensionless)
The ratio of stress to strain is known as the elastic modulus of the material
Elastic Modulus $=\frac{\text {stress}}{\text {strain}}$ Hence, the modulus of elasticity is dimensionally equivalent to the stress
