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.
Pressure is the force applied over a specific area, while stress is the internal force created within a material in response to an applied load. Pressure is usually external and uniform, while stress is internal and can vary depending on the material's properties.

What best describes the difference between differential stress and confining pressure?
Differential stress refers to the unequal forces acting on a rock that can result in deformation, while confining pressure refers to the uniform pressure applied from all sides on a rock mass. Differential stress can lead to the formation of geological structures like faults and folds, while confining pressure contributes to rock recrystallization and solid-state deformation.
Is pressure drop the same as pressure differential?
Pressure drop refers to the decrease in pressure between two points in a system, while pressure differential is the difference in pressure between two points. Pressure drop is usually a result of friction or resistance within a system, leading to a decrease in pressure, while pressure differential is simply the comparison of pressures at two different locations.
What is the formula for vaccum force?
The formula for vacuum force can be calculated as: Vacuum force = Pressure difference x Area Where the pressure difference is the difference in pressure between the vacuum and the surrounding atmosphere, and the area is the surface area over which the force is acting.
What is the difference between pressure part and nonpressure part?
Pressure parts are components of a system that are exposed to high pressure, such as boilers or pressure vessels, while nonpressure parts do not experience high pressure. Pressure parts are designed to withstand the stresses induced by high pressure, while nonpressure parts may not need to meet the same stringent requirements.
What is a pressure gradient and how is it related to air movement?
A pressure gradient is the change in pressure over a distance. Air moves from areas of higher pressure to areas of lower pressure due to the pressure gradient force. The greater the pressure difference, the stronger the force and the faster the air movement.
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 the difference between C16 and C24 stress grading?
C8 stress
What is the difference between external stress and emotional stress?
External is out side emotional is in
What is the difference between stress and conflict?
Stress is a bodies response and conflict is a disagreement.
What is the difference between stress coat and stress coat plus?
The latter is more effective.
What is the difference between thrust and pressure-?
what is the difference between thrust and pressure?
What is the difference between repetitive stress injury and repetitive strain injury?
there is no difference

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.
