elongation noun Definition, pictures, pronunciation and usage notes


Britannica is the ultimate student resource for key school subjects like history, government, literature, and more. The ratio of the extension of a material to the length of the material prior to stretching. The angular separation of a planet from the sun or of a satellite from a planet, as seen by an observer. The amount of extension of an object under stress, usually expressed as a percentage of the original length.

  • Brachytherapy source means a radioactive source or a manufacturer-assembled source train or a combination of these sources that is designed to deliver a therapeutic dose within a distance of a few centimeters.
  • A genetic condition is responsible for his slender physique and the elongation of his limbs.
  • Tearing off the crystal from the melt—the pulling rate is quickly increased until to form a conical tail and separate the crystal from the melt.
  • When an inferior planet is visible before sunrise, it is near its greatest western elongation.

It is said to be in quadrature when it lies at a right angle to a line between the Earth and Sun with an elongation of 90°, and it is in opposition when it lies on the opposite side of Earth from the Sun with an elongation of 180°. Superior planets have a full range of elongations between 0° and 180°. Inferior planets have limited elongations due to their smaller orbits; Venus has a greatest elongation of about 48°, while Mercury’s greatest elongation is about 28°. Elongation at Break measures how much bending and shaping a material can withstand without breaking. The measured elongation at break values is an indication of the ductility of a polymer. Elongation of a pipe is the increase in its diameter when stressed under tension. Flexible pipe materials such as high density polyethylene and polyvinyl chloride can elongate when the embedment soil along the pipeline is compacted.

Words related to elongation

The period depends on the relative angular velocity of Earth and the planet, as seen from the Sun. The time it takes to complete this period is the synodic period of the planet. This diagram shows various possible elongations (ε), each of which is the angular distance between a planet and the Sun from Earth’s perspective. Plastic sheeting, regardless of gauge, or similar products do not satisfy this requirement.


High-throughput techniques enable advances in the roles of DNA and RNA secondary structures in transcriptional and post-transcriptional gene regulation. HSF1 phosphorylation establishes an active chromatin state via the TRRAP-TIP60 complex and promotes tumorigenesis. Rigid plastics, especially fiber reinforced ones, often exhibit values under 5%.

Since asteroids travel in an orbit not much larger than the Earth’s, their magnitude can vary greatly depending on https://accounting-services.net/. More than a dozen objects in the asteroid belt can be seen with 10×50 binoculars at an average opposition, but of these only Ceres and Vesta are always above the binocular limit of +9.5 when the objects at their worst points in their orbital opposition . Thus Venus’s synodic period, which gives the time between every two eastern greatest elongations, is 584 days; this also applies to the western counterparts.

Brachytherapy source means a radioactive source or a manufacturer-assembled source train or a combination of these sources that is designed to deliver a therapeutic dose within a distance of a few centimeters.

What is elongation length?

Elongation is defined as the length at breaking point expressed as a percentage of its original length (i.e. length at rest). If a rubber reaches twice its length before breaking its elongation percentage is 100%.

These values vary because the planetary orbits are elliptical rather than perfectly circular. Another factor contributing to this inconsistency is orbital inclination, in which each planet’s orbital plane is slightly tilted relative to a reference plane, like the ecliptic and invariable planes. The combination of high ultimate tensile strength and high elongation leads to materials of high toughness. As the pulling stress reaches, and then passes, the tensile strength, the material fractures or breaks. However, when any stress less than tensile strength is removed from a material, it returns to its original shape and size, either completely or nearly completely. In astronomy, a planet’s elongation is the angular separation between the Sun and the planet, with Earth as the reference point. The greatest elongation of a given inferior planet occurs when this planet’s position, in its orbital path around the Sun, is at tangent to the observer on Earth.

Exfiltration means any unauthorized release of data from within an information system. This includes copying the data through covert network channels or the copying of data to unauthorized media.

Elongation, in astronomy, the angular distance in celestial longitude separating the Moon or a planet from the Sun. The greatest elongation possible for the two inferior planets is about 48° in the case of Venus and about 28° in that of Mercury.

What is elongation of a material?

“Elongation at Break” is a measurement that shows how much a material can be stretched — as a percentage of its original dimensions — before it breaks. This is also referred to as percent elongation, which is a measurement of the amount a material will plastically and elastically deform up to fracture.

Buried pipes are subject to soil pressure from the sides as well as the top and also to effects of gravity, temperature changes and external loading either dead or live. Material Test Certificate giving chemical composition, physical properties such as ultimate tensile strength, Elongation %, yield strength, hardness of finished product etc.


When it lies on the opposite side of Earth from the Sun with an elongation of 180°. The angular distance in degrees of a planet or the moon from the sun, as viewed from the earth.

Oxford English and Spanish Dictionary, Synonyms, and Spanish to English Translator

In the case of the moons of Uranus, studies often deal with greatest northern elongation and greatest southern elongation instead, due to the very high inclination of Uranus’ axis of rotation. Greatest elongations of a planet happen periodically, with a greatest eastern elongation followed by a greatest western elongation, and vice versa.

Elongation at Break is measured in % (% of elongation vs. initial size when break occurs). Frameshifts can obviously be disastrous for protein synthesis, leading to the expression of garbled protein sequences. However, there are numerous examples of programmed frameshifts that occur in conjunction with ribosome stalling on the mRNA template, and that lead to expression of a functional protein by translation within an alternate reading frame. Such programmed frameshifts are commonly seen in the expression of proteins encoded by phage or virus nucleic acid, but can occur for endogenous proteins as well.
