Simile It is a term with origin in the Latin word similis which refers to the like . The concept, therefore, is used to establish a comparison between two things. For example: "Paula has a cocker-like dog-like hairstyle that is very nice", “I have a blender simile car: when walking, it shakes everywhere”, "Be careful with those rosehip simile fruits as they are toxic and cannot be eaten".

In the literature , simile is a Figure of speech which consists in the express comparison between one thing and another, to give an effective idea of ​​one of them. When establishing the comparison by similarity, the symbolic or physical characteristics are transferred from one to the other.

Unlike the figure of the metaphor, similes appeal to relationship elements such as "what", "as" or "which". The phrase "His eyes like two emeralds shone in the night" It is a simile that draws a parallel between green eyes and precious stones. It is possible to say that the simile is a type of metaphor, although the same does not happen the other way around. This last resource substitutes terms for others whose meaning is different, while the former uses them simultaneously.

Similes appear in literary works as a way to convey a message and to provide a distinctive aesthetic feature: "The intricate streets like a labyrinth delayed the traveler, who could not find the address they had indicated", "His fists as missiles crashed on the wall at the tragic news", "The lineman was accompanied by dogs as guardian angels guarding his steps".

It should be noted that similes are also used in the daily life spontaneously: "Be careful if you go out at night that the street is dark like a wolf's mouth", “Fabio is tall and skinny like a lamppost”. In this context, such comparisons may have derogatory dyes or serve to emphasize an idea or advice, for example.

The use of similes in the language Popular is very common in informal conversations, as opposed to its use in literature, which can express more complex ideas than those seen with the naked eye. When these are not phrases made, these comparisons are included in oral communication to exaggerate certain observations and often add humorous touches to speech. It should be noted that not all cultures make use of this resource in the same proportion.

Hydraulic simile

A hydraulic simile is known as a circuit similar to an electric one that serves to make the water move. In order for the liquid to circulate along a certain path it is necessary that its level be higher in one of the two tanks used and that the slope be maintained with a pump, so that the circulation is carried out continuously.

To understand the comparison with an electric circuit, it is important to mention that the role that the pump plays in this case (of maintaining the difference between both tanks) is played by a battery, which in its context manages the voltage.

The resistance of a hydraulic simile is based on the following three variables: the width of the pipe, the elbows and the narrowings. On the other hand, the intensity of the water that passes through the circuit (also known as flow) depends directly on the height and inversely proportional to the resistance.

In other words, when the height increases, so does the flow and, in the same way, there is a direct proportion between the intensity and the voltage. When the section of the pipe increases, the resistance decreases and the flow becomes greater. It follows that a relationship exists inversely proportional Between intensity and resistance.
