answered-by-expert Expert Answer

Stress- It is defined as the external(deforming) force applied per unit area acting perpendicularly to the surface of the area.

Mathematically,
Pressure = ( Deforming(external)Force)/(Area)

Stress on a body is used to deform it.

Pressure is defined as the force per unit area acting perpendicularly to the surface of the area. Mathematically,

Pressure = Force/Area
