Difference between Stress and Pressure

Education

If you are wondering about the difference between Stress and Pressure, then you have approached the right page for this purpose. In this article, you will not only learn the difference between stress and pressure but also discover the definition of these two scientific terms.

These two terms are frequently used in science and technology courses. People often get confused with stress and pressure as they portray similar meanings to some extent. However, they possess different characteristics that are very important to know.

Moreover, both possess the same units of Newton. In order to remove all the ambiguities, first of all, let’s discuss what these two terms are.

Stress

Stress can be defined as “The amount of force per unit area experienced by a material.”

Stress is an internal force applied to the object. It affects the object from the inside.

Stress may be tensile, compressive, and shear.

Stress is used in material engineering.

Pressure

Pressure can be defined as “The amount of force applied per unit area.”

The pressure is the external force of an object. It affects the object from the outside.

The pressure is always compressive.

The pressure is used in mechanical things.
