Answer / shirin.r.s

Stress is actually resistance force produced in the body per
unit area when the body is strained.In plastic meterial this
resistance force is very negligible so it does not regains
its shape after deforming force is removed.But in elastic
meterial strain produces appreaciable internal resistance
force and its tends to regains its orginal shape.So i think
strain producess stress in elastic meterials.

Answer / nikhil_p_mech

Strain is "the change in dimension to the original dimension
on applying external force" whereas Stress is "the internal
resisting force (resistance force created by body) developed
per unit area". so Strain gets produced in the body on
applying external force, and to this developed Strain the
Stress developed in the body tries to oppose. Hence the
STRAIN PRODUCES STRESS.
Also, We know the Stress- Strain diagram, in which Stress is
on the Y-axis (ordinate)(for dependent variable) and the
Strain is on the X-axis (abscissa) (for independent
variable). So from this also we can say that,STRAIN PRODUCES
STRESS.

#Answer 1 & #Answer 2
it is not necessary that strain always produces stress .for instance thermal strain in a both end bar never produces stress (case of free elongation). Moreover stress need not necessarily produce strain ,as in case of constraint heating of cube.(thermal stress present but no strain permitted due to constraints ).
So these answers are not wrong but neither fully correct too.

Answer / satheesh

stess will produce stain,but strain will not produce any
steess, how means stress is the force that we are applying
on perticular instance,so that deformation takes place in
that body,that deformation is only we called as stress.

why we use kg/cm2 instead of kg/m2 as a unit of pressure. As we know kg is a MKS unit and cm is a CGS unit. So why we use combination of both(kg/cm2)while describing the pressure.
