# What is Dimensional Formula of Tensile Modulus , Modulus of Elasticity, Young modulus?

Posted in Dimensional Formulae | Email This Post |Tensile Modulus , Modulus of Elasticity, Young modulus is defined as the stress required to cause a unit strain in the material. It is the ratio of linear stress to linear strain.

Mathematically,

**Tensile Modulus , Modulus of Elasticity, Young modulus = linear stress / linear strain.**

Dimensional Formula of linear stress = M^{1}L^{-1}T^{-2}

Dimensional Formula of linear strain = M^{0}L^{0}T^{0}

Substituting in the above equation we get,

**Dimensional Formula of Tensile Modulus , Modulus of Elasticity, Young modulus = M ^{1}L^{-1}T^{-2}**

**SI unit of Tensile Modulus , Modulus of Elasticity, Young modulus = N m**
