what is the difference between stress and pressure?..

Answer / dharun

when the external force is applied on the elastic body,the
body will deform from its original position.there will be an
internal resistance force which will act opposite to the
external force with the same magnitude.the internal
resistance force per unit area is called stress.....
pressure is the force which will act normal to the surface
and all over the surface..........

what is the difference between stress and pressure?..

Answer / manojsub

I give you a simple example for this, If you blow a balloon
air that is inside. the balloon exerts a force on the
balloon (this force per unit normal area is pressure), Due
to this force an internal reactional or resistant force will
be created (this force per unit normal area is stress).

Pressure is a scalar while stress is a tensor quantity.
COZ, pressure only has magnitude and acts always towards a
surface, and stress could act in either way, and it also
gives the plane, in which it acts (That is why it is a tensor).
