Question

what is the unit and dimension of youngs modulus of elasticity

Answer 1

Hey, mate here is your answer》》


Young's modulus is the ratio of stress, which has units of pressure, to strain, which is dimensionless; therefore, Young's modulus has units of pressure. From my reasoning if something is dimensionless, it should be a unitless ratio.

The SI unit of Young's Modulus (E) is Pascal (N/m^2). But you can always see the material Young's modulus is written in GPa (10^9 Pa).
