Vedclass · Answer

(B) Stress is defined as the restoring force per unit area,given by $	ext{Stress} = \frac{	ext{Force}}{	ext{Area}}$.Its dimensional formula is $\frac{[MLT^{-2}]}{[L^2]} = [ML^{-1}T^{-2}]$.Pressure is defined as the thrust or force acting normally per unit area,given by $	ext{Pressure} = \frac{	ext{Force}}{	ext{Area}}$.Its dimensional formula is also $\frac{[MLT^{-2}]}{[L^2]} = [ML^{-1}T^{-2}]$.Therefore,the dimensions of stress are equal to the dimensions of pressure.
