# Difference between tension and compression

Tension and compression refer to forces that try to deform an object. The main difference between tension and compression is that tension generally looks at the forces that try to lengthen a body, while compression usually refers to the forces that try to shorten the length of the body. Tension and compression are two concepts discussed in physics. Tension is a force, while compression is a phenomenon.

These two concepts play an important role in fields such as mechanical systems, automobile engineering, heat engines, materials science, pendulums, and other fields. Having a proper understanding of tension and compression is vital to excelling in these fields.

In this article, we are going to discuss what compression and tension are, their definitions, the applications of compression and tension, the similarities between compression and tension, and finally the difference between compression and tension.

## Key differences

• Tension is a force that tries to lengthen an object, while compression is a force that tries to shorten an object.
• Tension can be related to pulling 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 force propagation; Compression can be used to transfer force as pressure in hydraulic systems, but there is no compression process.
• Tension is considered a force, but compression is a phenomenon.
• The direction of a force in tension is out of the object, while in compression the direction of the force acting on the object is always inward of the object.
• Tension is a force, while compression is a phenomenon. Tension is only valid on solid ropes, but compression can be applied to any material.
• 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 towards the body.
• Tension is a method of enacting forces; conversely, compression can be used to transfer force in the hydraulic system as pressure.
• Tension only applies to solid strings; on the contrary, compression can be valid for any material.
• Examples of tension are ropes, crane cable, nails, wires, etc. while an example of compression is the concrete columns.
• In tension, the force acting on the object is always outside the object. In compression, the force acting on the object is towards the inside of the object.

## Tension vs Compression – Overview

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 move away from it, while if a body is in compression, the forces acting on it are directed toward the body.

Tension can be related to pulling 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; Rather, compression can be used for force transfer in hydraulic system as pressure, but compression procedure does not occur. Tension is considered force, but compression is a phenomenon. Tension only applies to solid strings; Conversely, compression can be valid for any material.

The force in tension acting on the object is always outwards from the object, while in compression the force acting on the object is always inside the object. Examples of tension are ropes, crane cable, nails, wires, etc. while an example of compression is the concrete columns.

## What is tension?

Physics describes tension as the pulsating force that is transmitted axially through a cable, chain, rope, similar one-dimensional objects, or similar three-dimensional objects. Tension is the opposite of compression and is also defined as the pair of action-reaction forces acting at each end of the object. The molecules that make up the string are forced away from their equilibrium positions due to the tension that was created in a string.

The molecules pull back the objects that try to lengthen that string by moving towards its equilibrium position. If the forces in the molecules balance out, then the system reaches equilibrium, although the string is still under tension and perhaps elongated beyond its original length.

Stress per unit area (the area mentioned here is the cross-sectional area of ​​an object, which is at right angles to the force) is often called tensile stress. The increase in length divided by the original length of the body is called tensile strain. The two types of ropes will be discussed: a weightless rope is a so-called weightless rope, and a real rope is a rope with a fixed amount of weight.

Tension arises at each point on the string when a string pulls on an object and this is mainly due to intermolecular attractions. Links resist deformation when a force tries to expand the string. This tension causes a succession of balanced forces along the string.

In this way, stress can be considered a method of force propagation.

In this way, stress can be considered a method of force propagation. Tension is defined as the pulling force exerted by a cable, rope, chain, or similar object. There are two types of strings. A weightless rope is a hypothetical weightless chain.

A real chain is a chain with a finite amount of weight. These two definitions are important to describe stress. When an object is pulled by a string, tension occurs at each point on the string. This is due to intermolecular attractions. The bonds between the molecules act like little springs, preventing the two molecules from separating. When a force tries to stretch the rope, these links resist deformation.

This causes a series of balanced forces throughout the string. Only the two ends of the rope have unbalanced forces. The unbalanced force in the extreme, in which the initial force is acted, is balanced with the initial force. The unbalanced force at the end of the object acts on the object.

In this sense, tension can be considered as a method of force propagation. If the chain has a weight, the chain will not be horizontal, so the weight of the chain must be added to the calculation.

## What is compression?

In physics, compression is a balanced inward force (“pushing”) to different points on a material or object, that is, an unpaired net or sum force committed to reducing its size in one or more directions. For example, if we press a spring, we are applying a compressive force on it.

Compression is called uniaxial if the compression forces act in one direction. 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 pressure on the body (stress) and body tension is Young’s modulus. The compressibility factor for gases is defined as PV / RT, where P is the pressure, V is the measured volume. Compression is the reduction in the volume of a gas, liquid or solid due to external forces acting on it. Compression itself is not a well-defined quantity.

It can be taken as the amount of reduced volume or the percentage of the amount of reduced volume. The quantitative measure of compression is Young’s modulus for solids and the compressibility factor for gases. Young’s modulus is the relationship between the pressure on the object (stress) and the stress on the object.

Since stress is dimensionless, the units of Young’s modulus are equal to the units of pressure, which is Newton per square meter. For gases, the compressibility factor is defined as PV / RT, where P is the pressure, V is the measured volume, R is the universal gas constant, and T is the temperature in degrees Kelvin.

## Conclution

The above discussion 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.
