Dimensions of stress are:

  1. A
    \( [\text{ML}^2\text{T}^{-2}] \)
  2. B
    \( [\text{ML}^0\text{T}^{-2}] \)
  3. C
    \( [\text{ML}^{-1}\text{T}^{-2}] \)
  4. D
    \( [\text{MLT}^{-2}] \)
View Answer & Solution

Correct answer · Option C

\( [\text{ML}^{-1}\text{T}^{-2}] \)

Explanation

Stress is defined as force per unit area: \( \text{Stress} = \frac{\text{Force}}{\text{Area}} = \frac{[\text{MLT}^{-2}]}{[\text{L}^2]} = [\text{ML}^{-1}\text{T}^{-2}] \).
