Stress is restoring force developed in the body due to any tensile, compressive or any other force per unit area and on the other hand pressure is force applied on a body per unit area.

Brother as you said, but in some cases like in wall, eg. we are pressure applied on the wall it is also a scalar quantity.....so, how would we say pressure is only applied in case of fluid..

KAMAL SHARMA

1. Pressure applied on fluid (Gas & Liquid) where as stress applied on solid.
2. Pressure act perpendicular only where stress act perpendicular as well as inclined also.
3. Pressure is only +ve magnitude but stress have both +ve and -ve.
4. Pressure is external force and stress is internal force
