*Here, we will find out the dimensional formula of Stress.*

This Dimensional formula will be applicable for all the following types of stresses, – (1) **Longitudinal stress** (**Tensile and Compressive stress**) (2) **Tangential or Shearing Stress**, (3) **Hydraulic Stress**

**The formula of Stress = force/area **

The dimensional formula of force = [MLT^{–2}] [see here how to find the dimensional formula of force ]

The dimension of area = [L^{2}]

**Hence, the Dimensional formula of Stress **

=

**The dimensional formula of force / The dimensional formula of area**

**= [MLT**

^{–2}]/[L^{2}]=

**[ML**

^{-1}T^{–2}] **Dimensional formula of Stress**

**=**

**[ML**^{-1}T^{–2}]Dimensional formula of Stress – how to find it?
