Q157

Young's modulus is defined as the ratio of

A.
Volumetric stress and volumetric strain
B.
Lateral stress and lateral strain
C.
Longitudinal stress and longitudinal strain
Answer
D.
Shear stress to shear strain

Answer: Option C

Solution

Answer: Option C
Solution:
Young's modulus is defined as the ratio of longitudinal stress to longitudinal strain.

Longitudinal stress: This is the force per unit area applied in the direction of the length of a material.

Longitudinal strain: This is the deformation or change in length divided by the original length of the material.

Young's modulus provides a measure of the stiffness of a material and is a fundamental property in the field of strength of materials.
