Normal Stress
The normal force is the stress that arises when an axial force is applied to a component. In other words, when the stress imparted to the body is perpendicular. When the object’s length and volume are altered, the object’s stress level returns to normal. The symbol is represented by it. Normal stress is measured in millipascals (MPa) in the SI system.
Formula of Normal Stress
Normal Stress = Axial Force / Cross-sectional Area
When an object is in tension or compression, normal stress occurs. Normal Stress is further classified into two categories that are,
- Longitudinal Stress
- Bulk Stress
Now let’s learn about them in detail.
What is Stress?
Stress in physics is defined as the force exerted on the unit area of a substance. Stress affects the body as strain in which the shape of the body changes if the stress is applied and sometimes it gets permanently deformed. On the basis of the direction of force applied to the body, we can categorize stress into three categories that include,
- Longitudinal Stress
- Bulk Stress
- Shearing Stress
Apart from these three, there are also other types of stress that we will learn in this article. In this article, we will also learn about what is stress, the types of stress, the Formula for stress, the unit of stress, and others in detail.
