1. [MLT⁻²] 2. [ML²T⁻²] 3. [ML⁰T⁻²] 4. [ML⁻¹T⁻²]

Answer: 4. [ML⁻¹T⁻²] Stress =force/area . [stress]=frac[MLT⁻²][L²]=[ML⁻¹T⁻²] This is the same as the dimensions of pressure. Answer: option 4.

Dimensions of stress are :

1. $[MLT^{-2}]$

2. $[ML^2T^{-2}]$

3. $[ML^0T^{-2}]$

4. $[ML^{-1}T^{-2}]$

Best answer

Answer: 4. $[ML^{-1}T^{-2}]$

Stress $=\dfrac{\text{force}}{\text{area}}$.

$$[\text{stress}]=\frac{[MLT^{-2}]}{[L^2]}=[ML^{-1}T^{-2}]$$

This is the same as the dimensions of pressure. Answer: option 4.
