What is Stress?
Stress in physics is defined as the force we apply to an object divided by the cross-section area of the object on which the force acts.
The force applied to any object deformed the shape of the object and to restore the object to its original shape an internal restoring force is applied to the object. The internal force acting per unit area of the object is called the stress.
Stress Definition
Stress is defined as “The restoring force per unit area of the material”.
- Stress is a Scalar Quantity, and it’s denoted by σ.
- Stress is measured in Pascal or N/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.
