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. It may also be thought of as the internal resistive response of a material to the applied external pressure. They both have the units of force / area.

think it as-
suppose we have a cubical solid mass. we apply external force of few magnitude on it and this force will try to deform the cube. at the same instant an internal force will generate within the cube that will try to maintain the shape and size of the cube i.e. this internal force will work against the applied external force. this induced force within the cube is stress.

What is the difference between stress and fatigue?

Faitgue and stress, in engineering terms: Stress is the physical force on a body, for example column load on foundation pads. Fatigue is weakness in metal that makes it likely to break, caused for example by frequent stress (shaking due to loading) over a long period.

What is the difference between negative stress and positive stress?

Positive stress is called Eustress and it is a normal part of our everyday life. This type of stress positively affects us and keeps us going. It has a motivational effect and increases our activity and productivity. Eustress is essential for our success and has to be praised. The other negative ty (MORE)

What is the difference between good stress and bad stress?

Whether stress is good or bad is very unique to an individual. Things that cause you stress, often called stressors, are dealt with by using coping skills. Coping skills are simply your actions in response to a stressor. Coping skill can be healthy or unhealthy. So whether stress is good or bad is m (MORE)

What is the difference between stress and true stress?

I'm assuming you mean the difference between true stress and engineering stress: Engineering stress is only accounting for the area given at the time before deformation. True stress accounts for the change in area that occurs as the material is stressed. If you stay in the elastic region, there will (MORE)

What is is the difference between stress and anxiety?
