Physics And Measurement Question 73
Question: Dimensional formula of stress is
Options:
A) $ M^{0}L{{T}^{-2}} $
B) $ M^{0}{{L}^{-1}}{{T}^{-2}} $
C) $ M{{L}^{-1}}{{T}^{-2}} $
D) $ ML^{2}{{T}^{-2}} $
Show Answer
Answer:
Correct Answer: C
Solution:
Stress = $ \frac{Force}{Area}=\frac{[ML{{T}^{-2}}]}{[L^{2}]}=[M{{L}^{-1}}{{T}^{-2}}] $
