Hooke's LawMediumQuestion 6304

Question

Modulus of elasticity = Stress/Strain. Its SI unit is:
  1. A
    Dimensionless
  2. B
    Pa (Pascal)
    Correct
  3. C
    N·m
  4. D
    J/m³

Correct answer

Pa (Pascal)

Explanation

Modulus of elasticity = Stress/Strain. Units of stress = Pa. Strain is dimensionless, so modulus is in Pa.
