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 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 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.
Difference between Stress and Pressure
There are many Difference between Stress and Pressure that people are unaware of.
Below is the table of the main difference between the stress and pressure,
|Difference between Stress and Pressure|
|Stress can be defined as “The amount of force per unit area experienced by a material”||Pressure can be defined as “The amount of force applied per unit area”|
|Stress can be represented as (strain) / (Young’s modulus)||Pressure can be represented as (force) / (area)|
|Due to stress, the pressure will not be developed||Due to pressure, stress will be developed|
|Stress can be either a positive or a negative force||The pressure is always a positive force|
|Stress is an internal force applied to the object||The pressure is the external force of an object|
|Stress affects the object from the inside||Pressure affects the object from the outside|
|Stress may be tensile, compressive and shear||The pressure is always compressive|
|Stress is used in material engineering||The pressure is used in mechanical things|
So, these were some of the key differences between stress and pressure. I hope you guys have now understood the difference between these two terms.
