    I wish to understand the real difference between pressure and stress? Isn't it one and the same thing?

    pressure is externaly applied on any body while the stress is internal resistance of the body

    pressure is an externally applied force per unit area, while stress is internally developed in a material when forces are applied.

    pressure acts in all directions, but stress acts only in one particular direction(in the direction of application of force).

    the above mentioned replies are good but you can also recognize the pressure as the 'CAUSE' and stress as the 'EFFECT'.

    difference between pressure and stress?
    pressure will act at one point in all direction and stress will act on particular area.

    Though both pressure and stress are functions of force and area, pressure distinguishes itself from stress in that it causes the exertion of force in all direction in the given area, while stress accompanies the applied force in a direction opposite to that of the applied force in a given cross-sectional area.

    Pressure is the external force acting over a unit surface area of a material. Stress is an internal force acting over a cross sectional area within the material.

    difference between pressure and stress?
    pressure is applied externally in any direction but stress is applied only in the opposite direction of force applied...

    stress is "induced" , not "applied"

    depends on ur analysis way it can be induced by itself and applied by resisting particle...
