Answer / gaurav

stress is internal property of material i.e the resistance
offered by material to exteranal applied force per unit
area,whereas the pressure is external prperty,it is the
distribution of force per unit area

Answer / ahtsham ahmad

i think that the difference b/w is HOW & WHERE THE FORCE
IS APPLIED.. THINK ABOUT THE WORD how which i have entered

Answer / srinivas vanamala

stress is restoring force per unit area.
pressure is force/area.

Answer / vahid

2 kinds of stress are available:

1-shear stress which is the force that its vecctor is in
the plane of the body acting on.

2-normal stress which is the force that its vector is
normal to the plane of the body acting on. (the direction
is outward of the surface while the pressure has the
direction toward the body)

Answer / salah mohammad ababneh

strength : is a property of a material which means that a ability of material to withstand the applied stress.

stress: is not a property of the material but it is the internal resistance of the material to the applied load per unit area to avoid the deformation

Answer / ricky

moment is tendency to move about a point while torque is a
movement about a point..

Answer / ravi

pressure is always compressive in perpendicular direction...whereas stress can be compressive,tensile or shear natured.

Answer / onecho angelo gabinete

These quantities are expressed in terms of force per unit
area. In the SI the unit based on the Newton per square
meter (N/m2). Similarly data used in strength-of-materials
calculations (Young’s modulus of elasticity, yield strength
and so on) are all expressed in terms of the Newton. It has
been recommended by the International Standards organization
that the special name for the basic unit for pressure and
stress should be the pascal (pa). This recommendation is
subject to approval by the CGPM. The basic unit N/m2 is very
small, it is only 0.15 x 10 lb/in2, hence the KN/m2 (= 1000
/N/m2) are much more frequently encounters. The latter is
sometimes written as N/mm2. In some countries the bar = 105
N/m2 and hectobar = 107 N/m2 are employed. The safest rule
is to convert to the basic unit before starting any
calculations.

Answer / nisar ahmad

moment causes banding stress
while torque causes torsional stress

Answer / dinesh patil

SRESS ON A BODY MAY EITHER BE EXTERNAL OR INTERNAL
i.e; EXT FORCE APPLIED=INTERNAL RESTORING FORCE
BUT

PRESSURE ALWAYS ACTS EXTERNALLY

OR..........

A THRUST IS CLASSIFIED UNDER PRESSURE BUT CANNOT BE SAID AS STRESS.
