Question

Is the unit of longitudinal stress same as that of Young’s modulus of
elasticity? Give reason for your answer.

Answer 1

Dear Student,

◆ Answer with Explanation -

Youngs modulus is calculated as -

Young's modulus = longitudinal stress / longitudinal strain

Therefore,

Unit of Young's modulus = Unit of longitudinal stress / Unit of longitudinal strain

As strain has no unit,

Unit of Young's modulus = Unit of longitudinal stress

Therefore, unit of Young's modulus is same as unit of longitudinal strain.

Thanks dear. Hope this helps you...
