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 pressure part and nonpressure part?
The difference between pressure and non pressure part
What is the difference between tension and pressure in physics?
There is a huge difference between tension and pressure in physics. Tension refers to a pulling force and pressure refers to a pushing force.

What is the Difference between Dynamic pressure and static pressure?
The main difference of static pressure and dynamic pressure is:- static pressure is exerted by fluid at rest but dynamic pressure is pressure exerted by fluid in motion.
Is pressure drop the same as pressure differential?
is pressure the same as stress ? Stress is merely related to physical or mental tension which may be a result of pressure exerted to a material or a person. So pressure may cause stress and is not the same. Pressure drop is the same as differential pressure as normally applied to measure the condition of a filter system. *** Not it is not The more scientific definitions are:- Pressure: compressive force acting on an area, expressed in units of force per unit of area, e.g. 1Pascal = 1 newton/metre (force) per square metre (area). Pressure differential: change Differential to the more grammatically and mathematically correct Difference and there's the definition - difference between two pressures in a system. Stress: force acting on an area, as above, but may be compressive or tensile. Psychological stress is another matter, and most speakers use the word "stress" without knowing its proper meaning when talking of personal problems. Strain: the change in shape of a medium under stress; e.g. compression of rubber or a gas, or the change in length of a spring under load.
What is difference between stress and intonation?
the differences between intonation and stress is the difference . ! :D :D hahahahahaa
What is The Law of Stress?
The Law of Stress states that Stress is the difference between Pressure and Adaptability of any kind. The law is expressed as a formula, S = P - A, or Stress = Pressure - Adaptability. This universal law is valid for physical, biological, and psychological stress. The Law of Stress concept was developed in 1978 by Dr. Robert Dato, an American Psychoanalyst.

What is differential air pressure?
Differential air pressure is a term of comparison. It may be stated as "the difference in air pressure between..." and finished from there. Let's look at a sentence and then break it down. "The differential air pressure across the body of the 747 is a cause of concern over the life of the aircraft." A jet at altitude has a pressurized cabin. The outside air pressure is very low. (Think Mount Everest. Almost no one climbs it without suplimental oxygen.) There is a difference between the air pressure inside the cabin and the air pressure outside the cabin. This is an instance of differential air pressure. The differential air pressure puts stress on the body of the plane. When the aircraft is back on the ground, the differential pressure disappears. The alternating application and neutralization of stress across the hull damages the structure over the life of the airframe. The differential pressure is the difference between the pressure of the air in the (pressurized) cabin at altitude and the pressure of outside air at that altitude.
