Question

The Young's Modulus can be defined as the ratio of which of the following?

• A. Normal stress and Normal strain
• B. Normal stress and Shear strain
• C. Shear stress and Shear strain
• D. Shear strain and Normal strain

Answer 1

Answer:

A. Normal stress and Normal strain

Young's modulus is the ratio of normal stress to normal strain and is denoted by E. Shear modulus, also known as the modulus of rigidity, is the ratio of shear stress to shear strain and is denoted by G. Bulk modulus is the ratio of normal stress to volumetric strain and is denoted by K.
