Stress Formula
The formula to calculate the stress acting on a body is,
Stress = (Restoring Force) / (Area of Material)
We use σ notation to denote stress thus,
σ = F / A
where,
- F is the Restoring Force is measured in Newton,
- A is the Area of Cross-Section of Material is measured in m2
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.
