Question

Taking force, length and time to be the fundamental quantities, find the dimensions of pressure .

Answer 1

Pressure
 \[= \frac{\text{ force}}{\text{area}}\]
\[\]
\[\left[ \text{ Area }\right] = \left[ L^2 \right]\]
\[ \therefore \left[\text{ Pressure }\right] = \frac{\left[ F \right]}{\left[ L^2 \right]} = \left[ {FL}^{- 2} \right]\]
