Question

Modulus of Elasticity, E (Young’s Modulus):

 

E = σ/e

 

 

 

e: Strain, unit-less

σ : Stress, in N/m2

E : Young's modulus (Modulus of Elasticity), in N/m2

 

a) Explain Young's Modulus (Modulus of Elasticity, E).
b) Using the engineering stress-strain curve above, measure and calculate the Modulus
of Elasticity, E (Young's Modulus) of the test specimen by calculating the slope of
the curve in the elastic region. (Show all your calculation in detail)
