# Difference Between Tension and Compression

Main difference

The main difference between tension and compression is that tension generally looks at forces trying to lengthen a body, while compression usually refers to forces trying to shorten the length of the body.

## Tension vs Compression

Tension is a force that tries to lengthen a body or an object, while compression is a force that tries to shorten the body or an object. If a body is in tension, then the general forces are directed away from it, while if a body is in compression, the forces acting on it are directed towards the body. The tension can be related to pulling on the ends of a rod; on the other hand, compression can be associated with pushing the ends of a rod toward the center. Tension is a method of enacting forces; On the contrary, compression can be used for the transfer of force in the hydraulic system as pressure, but a compression procedure does not occur. Tension is considered force, but compression is a phenomenon. Tension is only applied on solid strings; Conversely, compression can be valid for any material. The force in tension acting on the object is always towards the outside of the object, while in compression the force acting on the object is always towards the inside of the object. Examples of tension are ropes, crane cable, nails, threads, etc. while an example of compression is concrete pillars.

## What is compression?

In physics, compression is a balanced inward (“pushing”) force at different points on a material or object, that is, a force with no net torque or sum engaged in reducing its size in one or more directions. For example, if we press down on a spring, we are applying a compressive force on it. The compression is called uniaxial if the compression forces act in one direction. The compression will be called biaxial and triaxial if the compression forces act in two or three directions respectively. Young’s modulus is the quantitative measure of compression. The relationship between the pressure on the body (stress) and the tension in the body is Young’s modulus. The compressibility factor for gases defined as PV/RT, where P is the pressure, V is the measured volume,

## Key differences

1. Tension is a force trying to lengthen an object, while compression is a force trying to shorten an object.
2. The general forces move away from him. If a body is in tension, while if it is in compression, the forces acting on it are directed toward the body.
3. The tension can be related to pulling on the ends of a rod; on the other hand, compression can be associated with pushing the ends of a rod toward the center.
4. Tension is a method of enacting forces; on the contrary, compression can be used to transfer force in the hydraulic system as pressure.
5. Tension is considered a force, but compression is a phenomenon.
6. Tension is only applied on solid strings; on the contrary, compression can be valid for any material.
7. The direction of a force in tension is away from the object, while in compression the direction of the force acting on the object is always towards the inside of the object.
8. Examples of tension are ropes, crane cable, nails, threads, etc. while an example of compression is concrete pillars.

## Final Thought

The discussion above concludes that tension generally lengthens an object, while compression attempts to shorten the object in length. Tension is considered a force, while compression is a phenomenon.
