Longitudinal Stress
Longitudinal stress is defined as when the length of the body changes due to normal stress.
Formula of Longitudinal Stress
Longitudinal Stress = Deforming Force / Cross-Sectional Area
Longitudinal Stress stretches or compresses an object throughout its whole length. As a result, based on the direction of deforming force, it can be divided into two types – Tensile stress and Compressive stress
When a rod is stretched according to Newton’s third law of motion, tensile stress is visible. Tensile stress is commonly represented by a rubber band being stretched out. Compression is the polar opposite of tension. When it is acting on a rod that is pressed at both ends by opposing or equal forces. Compressive stress is what you get when you squeeze a rubber ball in your hands. Longitudinal Stress is further classified into two categories that include,
- Tensile Stress
- Compressive Stress
Now let’s learn about the same in detail.
Tensile Stress
Tensile stress is defined as stress that occurs when a deforming force or applied force causes an increase in the object’s length. When a rod or wire is stretched, for example, equal and opposite forces (outwards) are applied at both ends.
Compression Stress
The shape and volume of the body are altered when a tangential force is applied to it. The length of the body is reduced once compression load has been applied. Tensile stress and compression stress are diametrically opposed. Compression stress is created when you squeeze a pet’s squeak toy in your hand.
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.
