Answer / nitin

We know that every materials is elastic in nature , so when
a force is applied it tends to deform and due to this
deformation , there is an internal resistance produced
which tends to spring back the molecules to their original
position and this internal resistance per unit area is know
as STRESS .

Pressure is nothing but force acting on a unit area .

Answer / shams parwez

STRESS= the internal resistance developed due to the
application of external force.


PRESSURE=force per unit area

Answer / bhupendra sahu

difference between stress and pressure

stress=resistive force/area.

pressure=force/area.

Answer / banke bihari

stress is internal reaction where as pressure is external..

Answer / shashikanth s s

stress is internal resisance to external load where as
pressure is external force applied upon the surface

Answer / shams parwez

torque is the tendency of a force to rotate an object about
an axis.torque is also called 'moment' or moment of force or
twisting moment.
in physics sense it is called torque but
in mechanical engg. sense it is called moment.
torque is usually used to describe a rotational force of a
shaft while moment is more often used to describe a bending
force on a beam.
"moment is a synonym for torque"

Answer / ramji

for example if we take any rod and when we bend that it
wont deform initially. bcoz there is some internal
resistance will act against the deformation. That internal
resistance is called as stress.pressure is nothing but the
force what we are giving initially to bend that rod.

moment is the twisting force
but torque is one of the twisting moment.

Answer / bala

stress is the internal resistance caused by body when it is
subjected by any load.
But pressure is the external force act on the body.It
doesn't help to know the body whether it can withstand the
load or not.But the earlier helps for it.

Answer / bindeshwari pal

stress is the internal resistance set by the molecule.
stress=load/area

pressure=force/area

stress may be in tension or compression or shear.
pressure is only in compression

Answer / gurmeet singh

Moment is due to Bending of the shaft or the given material
And torque is developed due to rotation of the shafte.
