What is a bend? When pronouncing this word, an association with a turn immediately arises, which is close to reality. But at the same time, the “turn” has not one, but several meanings. Detailed information on this will be presented in the article.
Let's turn to the dictionary
In the explanatory dictionary, the meaning of the word “turn” is given in several versions. The first of them says that this is a sharp turn, movement along a curved line. This applies, for example, to the movement of a car, bicycle, airplane.
Example: “At first, the commander’s tank suddenly stopped, but suddenly he suddenly made such an intricate turn that it immediately became clear that the tank driver was clearly a guy with a difficult character.”
Etymology
If we turn to the etymological dictionary, we can see that in the translation from French the word “turn”, where it looks like virage, means “turn”. It comes from the French verb virer, which means "rotate, rotate."
For a better understanding of what a turn is, it seems appropriate to consider the meaning of the noun “turn”.
What is a rotation?
This word has two meanings in the dictionary.
According to the first of them, it denotes the place where the road changes its direction. This fully applies not only to the road, but also to the path, line, and also the course of events.
Example 1: "Soon, the bushes began to recede from the river bed, and after the next bend, a smooth valley with rare trees in the middle of tall, lush, bright grass opened its gaze."
Example 2: "Even if you take relatives of both family lines, you can count them on the fingers, therefore, the probability of a successful turn of events is too small."
The second meaning of the word “turn” is the action corresponding to the verb “turn”.
Example: “An animal with a long and thin tail with a small tassel at the end is able to make rather sharp turns when it moves quickly among trees and bushes.”
Next, the lexical meaning of the verb “rotate”, to which the dictionary refers, will be considered.
The meaning of the verb
The common prototypical meaning for the verb “turn” is to change the direction of something. But there are several shades of interpretation, which include such as:
- Change the position or direction of something, twirling, rotating. Example: “Then Anna Savelyevna sharply turned a slender face to the window and began to be baptized.”
- Change the direction of movement of something or someone. Example: “After the wind became gusty and squalls frequent, the captain was forced to turn the ship every three hours.”
- Intransitive verb in meaning - to change the direction of one’s own movement, course; start moving backwards to the side. Example: “Barin told the coachman to turn right and drive along the Smolensk road.”
- Rotate, change the direction of something with the help of rotational movements. Example: "He thoughtfully turned the globe in front of him."
- In a figurative sense, in colloquial speech - to reinterpret something, change the direction of something, change the course, give a different character. Example: "You are turning the conversation into a completely different plane."
Further, other interpretations of the word “turn” will be considered.
Other values
About what a bend is, the dictionary also says the following:
- A section on the road or as part of a sports facility (for example, a bicycle track) with a sharp turn, which also has an internal slope in the road surface - transverse and one-sided. Example: "When cornering on the road, the driver successfully fit into the turn and decided to reduce the speed - left the gas pedal and began to slow down."
- A portion in a channel or tray arrangement that is smoothly or curved that has a transverse bottom slope. Example: “An automatic bending device for trays is used in a makeshift incubator. This device has a gear motor that smoothly tilts the egg trays from one side to the other. ”
In the dictionaries you can find other meanings of the studied word.
Two more interpretations
These include such as:
- The saline solution used in the photograph in which the printed image is washed. This is done in order to give it a certain color. And also a bend-fixer, in which there is also fixing salt. Example: "The turn-fixer contains sodium thiosulfate - for fixing and salts of metals such as gold, lead, vanadium - for tinting."
- In aviation - aerobatics. Example: “A bend is a 360 ° turn of an airplane along a path whose radius of curvature is either constant or variable. It takes place in a horizontal plane. ”
In conclusion, we can consider in more detail what a turn is in piloting an airplane.
In aviation
Here, the bend is a simple aerobatics figure. During its implementation, the aircraft moves forward and turns 360 ° in a horizontal plane. The implementation of this figure is divided into parts.
The part that aims to change the direction of movement by an angle less than 360 ° is called a turn. A bend in which the roll angle and speed are constant is called steady. If such a turn is made without lateral sliding, it is designated as correct.
There is also a limit turn. To carry it out with maximum operational overload and maximum roll at a given height, all the power inherent in the aircraft propulsion system is used.
The main indicators characterizing the maneuverability of the aircraft in the horizontal plane are the radius of the turn and the time it takes to complete.
