What are the dimensions of stress?
Correct answer: A. MLT^-2
- A. MLT^-2
- B. ML^-2T^-1
- C. ML^-1T^-2
- D. ML^0T^-1
Explanation
Stress is defined as force per unit area and is expressed in units of pressure. The dimensional formula for pressure is force divided by area( p = F / A), which is MLT^-2 (mass × length × time^-2
