MCQ
Young's modulus of a material has the same units as
  • ✓
    Pressure
  • B
    Strain
  • C
    Compressibility
  • D
    Force
✓

Answer

Correct option: A.
Pressure
a
(a) $Y = \frac{{{\rm{Stress}}}}{{{\rm{Strain}}}} = \frac{{{\rm{Force/Area}}}}{{{\rm{Dimensionless}}}} \Rightarrow Y \equiv {\rm{Pressure}}$.
