Select the pair whose dimensions are same

A

Pressure and stress

B

Stress and strain

C

Pressure and force

D

Power and force

Answer

Pressure and stress

Explanation

Solution

Pressure =ForceArea=ML−1T−2= \frac{\text{Force}}{\text{Area}} = ML^{- 1}T^{- 2}

Stress =Restoring forceArea=ML−1T−2= \frac{\text{Restoring force}}{\text{Area}} = ML^{- 1}T^{- 2}
