The unit of modulus of elasticity is mcq

MCQ  

The unit of modulus of elasticity is ...........




Options 

A) N

B) m2

C) N / m

D) N / m2

Correct answer : option D ( solution discussed below)



Solution

The modulus of elasticity is a ratio of normal liner stress upon liner strain within proporional limit.

modulus of elasticity (E)
         = stress 
            strain

stress si unit is N/ m² and strain is unit less quanity
So the unit of modulus of elasticity is N / m² (Newton/meter²)
