Question

Dimensions of stress are:

A

$[M L^2 T^{-2}]$

B

$[M L^0 T^{-2}]$

C

$[M L^{-1} T^{-2}]$

D

$[M L T^{-2}]$

Step-by-Step Solution

Stress is defined as the restoring force per unit area. $\text{Stress} = \frac{\text{Force}}{\text{Area}}$ Dimensional formula of force $= [M L T^{-2}]$ Dimensional formula of area $= [L^2]$ Therefore, the dimensional formula of stress $= \frac{[M L T^{-2}]}{[L^2]} = [M L^{-1} T^{-2}]$ .
