The dimensions of stress is

Options

  1. AML - 1 T - 2
  2. BML - 3 T - 1
  3. CML 2 T - 2
  4. DML - 3 T - 2

Correct answer

A. ML - 1 T - 2

Step-by-step solution

Stress is defined as “The restoring force per unit area of the material”. It is a tensor quantity. Denoted by Greek letter σ . Measured using Pascal. ⇒ stress = Force Area ⇒ stress = M L T - 2 L 2 ⇒ stress = M L - 1 T - 2
