Stress and Pressure

Sometimes i am quite confuse with pressure and stress. Actually, they are the same thing as their definition of the equation are also the same just the presentation are different.

Pressure=Force / Area, Stress = Force / Area .

Are they the same?

Pressure are used on the medium which deform easily such as air pressure and liquid pressure while stress is used for a solid which is also deformable.

The unit for both pressure and stress are also differ, pascal, psi, bar, and atm for pressure while N/m^2 for stress.

What is for our human being ?

When human feel they are load with lot of task and assignment, they feel stress.

I think that will be the same theory as well when our brain are fill with a lot of information and task to settle. The more thing test/exam we need to take is analogous to the higher the force exert onto a body while the area remain the same. Thats why stress unit increase.

Haha...enough writing. Move on and manage it wisely.
