Pressure is also force acting per unit area , then what is the difference between Pressure and Stress?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Pressure is force acting perpendicular to the area.

 pressure is always act normal to the plane but stress may or may not be normal to the plane.it may act tangential or at certain angle to the plane............

 in simple words... stress is a kind of pressure...

hlo..........

pressure is simply force acting per unit area. pressure does not state that what type of force is. stress is deforming force per unit area. it means stress states that it is deforming force per unit area. means the force which causes the deformation in dimensions of body . i hope it wil help u

thanks

 when u hit anail inside a wood planck then u will see it is going inside it is due to its smaller area acting over the planck. the force which is acting perpendicularly by u on the hammer is the pressure while the force acting on nail due which there is a change in its dimensions ios called stress.
