The Unit of Young’s Modulus is Same as That of

Answer- A– Stress

The unit of young’s modulus is the same as that of stress.

Explanation-

According to Hooke’s law:

Stress ∝ Strain

σ ∝ ϵ

σ = Eϵ

where E = Young’s modulus of elasticity.

The unit of young modulus is the same as that of stress (σ) since strain (ϵ) is non – dimensional. Thus, E can be expressed in MPa, GPa N/mm², N/m², Pa, etc.
