Question

Coulomb’s Theory is also known as:

• A. Maximum Principal Stress Theory
• B. Maximum Shear Stress Theory
• C. Maximum Principal Strain Theory
• D. Total Strain Energy Theory

Hint:

For failure theories: - Maximum Shear Stress Theory is suitable for ductile materials.-Maximum Principal Stress Theory is used for brittle materials.

Answer 1

The Correct Option is B

Coulomb’s Theory is another name for the Maximum Shear Stress Theory, which states that failure occurs in a material when the maximum shear stress reaches a critical value. This theory is widely used in soil mechanics and failure analysis of ductile materials.
