Question { Kirloskar, 98814 }

what is the difference between stress and pressure?. what
is the difference between moment and torque?


Answer

stress, internal resistance developed per unit area.
pressure, force applied per unit area.

moment, bending force* distance from it is applied.
by this bendng effect produced.
torque, twisting force * distance from it is measured.
by this shearing effect produced.

Question { 40291 }

Which is more Elastic Steel or rubber? Plz give the reason
also........ mchandan86@gmail.com


Answer

according to me
rubber is more elastic than steel.
because elasticity is a property in which material goes
deformation which is not Permanent.
and steel has more resistance(strength) aganist deformation
of plastic and elastic

Question { 40291 }

Which is more Elastic Steel or rubber? Plz give the reason
also........ mchandan86@gmail.com


Answer

I need more clarification from all,
I think, you are thinking about elastic strength. elasticity
is different from elastic strength.
Of course steel has high elastic strength(youngs modulus)
but it has low elasticity. It couldn't get original shape
still the deformation is lower than rubber and elastomer
materials.
for an example take a piece of rubber and steel
under application of load rubber and steel both gets
deformation but rubber only can get its original shape after
removal of load(though the load is much lower than steel)
steel needs more load to deform because of high elastic
strength only.

Answer

under deformation ductile materials shows plastic
deformaion before failure.And we can observe cone& cup
