Answer Posted / tigiri
Pressure = force/area
Stress = load/area
Both stress and pressure have the same unit (N/m2)
The major difference is:
Pressure is the is an external force acting directly on a
body whereas stress is the internal effect of the force in
the material in which the force is acting.
Common example:
when yor are sitting on a chair, the force you are applying
on that chair is reffers to as PRESSURE whereas the
internal effect of this force in the chair/material is
known a STRESS.
