Young's modulus` is defined as the ratio of

Options

A. bulk stress and longitudinal strain
B. hydraulic stress and hydraulic strain
C. shearing stress and shearing strain
D. tensile stress and longitudinal strain

Answer

D

Explanation

Young's modulus is elastic property of a material which is defined as the ratio of tensile stress and longitudinal strain.
`Y= (F//A)/(Deltal//l)= ("Tensile stress")/("Longitudinal strain")`
