MCQ
The modulus of elasticity is dimensionally equivalent to
  • A
    Surface tension
  • Stress
  • C
    Strain
  • D
    None of these

Answer

Correct option: B.
Stress
b
(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
