coupling

Coupling is he act and result of coupling. East verb make reference to link, combine, arrange, join, or adjust two or more items. For example: "The coach aspires to achieve the engagement of the players as soon as possible", "The coupling of the satellite navigation system to all the vehicles of the security forces will be completed in the coming weeks", "I have not finished assembling the furniture yet, I am missing the coupling of the shelves".

According to the dictionary of the Royal Spanish Academy (RAE), coupling is also the union that animals establish when they develop a sexual encounter. In this case, the verb is used reflexively, and therefore it is said that the animals I know they mate, that is, they mate.

The idea from mechanical couplingOn the other hand, it refers to the system of chains or ligaments that, with less or more freedom, connects different units. These couplings can be articulated, flexible or rigid.

When a minimum of two leagues has the possibility of moving, it is spoken of mechanism. To carry out the design of a mechanical coupling, it is normal to include an input and produce an output, alter the values ​​of speed, acceleration and movement, and apply a mechanical advantage. Mechanical couplings that are created to be stationary are known by the name of structures.

Although the concept may seem somewhat abstract at first glance, most of us have at least one item in the home made based on the principles outlined above. A clear example is the pliers, a tool used to mold certain materials or hold parts, among other objectives: it is a mechanism, and its degree of freedom is one.

A magnetic coupling implies that a current of electricity passes through a coil generating a potential difference that appears between the ends of the rest of the coils that make up the electrical circuit in question. The phenomenon It can be explained from two physical laws, Faraday's and Ampère's.

The law de Ampère tells us that any variable electric current tends to create a proportional and variable magnetic field with the passage of time. Faraday's, on the other hand, explains that when time-varying magnetic fluxes pass through a surface that is closed by a circuit, they induce a potential difference.

The concept of tidal coupling is used to describe what happens when the face of a certain astronomical object always points to another object. This means that the coupled object, when rotating on its axis, takes the same time as it takes to carry out the translation around the other. A case of tidal coupling is one that takes place between the Moon and the Land: from our planet we always observe the same face of the satellite.

Thanks to this phenomenon, one hemisphere of the object that rotates around the other always points towards it. Usually this happens only in the satellites that are docked around a planet bigger than themselves; however, when there is neither a great mass difference nor a considerable distance between the two, the two may show a reciprocal tidal coupling, just as it happens between Charon and Pluto.

In the field of three-dimensional computer image design, a technique called billboarding which consists of making a flat Textured always points towards the active camera so that the user believes that it is a three-dimensional object. This is very similar to the concept of tidal coupling, and was very common in the first three-dimensional video games, which emerged in the early 90s, although even today it still has some usefulness.
