Elastomer
An elastomer is a polymer with viscoelasticity (i.e. both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus and high failure strain compared with other materials. The term, a portmanteau of ''elastic polymer'', is often used interchangeably with rubber, although the latter is preferred when referring to vulcanisates. Each of the monomers which link to form the polymer is usually a compound of several elements among carbon, hydrogen, oxygen and silicon. Elastomers are amorphous polymers maintained above their glass transition temperature, so that considerable molecular reconformation is feasible without breaking of covalent bonds. At ambient temperatures, such rubbers are thus relatively compliant ( E ≈ 3 M Pa) and deformable. Their primary uses are for seals, adhesives and molded flexible parts. Application areas for different types of rubber are manifold and cover segments as diverse as tires, soles for shoes, and damping and ...

Elastic (notion)
In sewing, elastic is a notion which is sold in narrow strips and generally serves to increase the ability of garment to stretch, either to accommodate movement or to make the garment suitable for wearers of many different physical sizes. Elastic comes in four forms of construction, each with costs and benefits. The component which performs the actual stretching is made of either rubber or a synthetic material such as spandex; this stretching component is then covered with polyester, cotton, nylon, or a combination of these or other fibers which allow it to be attached to clothing. High-quality elastic is able to be stretched to twice its original length and then return to its unflexed state without showing appreciable wear. Types Elastics may be either braided, knitted, woven, or transparent. Braided Braided elastic, the most common form of elastic, becomes more narrow as it stretches. Stitching or piercing this kind of elastic causes it to quickly lose its ability to retu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stretch Fabric
Stretch fabric is a synthetic fabric that stretches. Stretch fabrics are either 2-way stretch or 4-way stretch. 2-way stretch fabrics stretch in one direction, usually from selvedge to selvedge (but can be in other directions depending on the knit). 4-way stretch fabrics, such as spandex, stretches in both directions, crosswise and lengthwise.Types of stretch fabrics - Stretch Fabrics It is distinct from which is not a fabric but a notion.

Rubber Band
A rubber band (also known as an elastic band, gum band or lacky band) is a loop of rubber, usually ring or oval shaped, and commonly used to hold multiple objects together. The rubber band was patented in England on March 17, 1845 by Stephen Perry. Most rubber bands are manufactured out of natural rubber or, especially at larger sizes, an elastomer, and are sold in a variety of sizes. Notable developments in the evolution of rubber bands began in 1923 when William H. Spencer obtained a few Goodyear inner tubes and cut the bands by hand in his basement, where he founded Alliance Rubber Company. Spencer persuaded the ''Akron Beacon Journal'' as well as the ''Tulsa World'' to try wrapping their newspapers with one of his rubber bands to prevent them from blowing across lawns. He went on to pioneer other new markets for rubber bands such as: agricultural and industrial applications and a myriad of other uses. Spencer obtained a patent on February 19, 1957 for a new "Method for Maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bungee Cord
Bungee cords equipped with metal hooks A bungee cord (sometimes spelled bungle; also known as a shock cord) is an elastic cord composed of one or more elastic strands forming a core, usually covered in a woven cotton or polypropylene sheath. The sheath does not materially extend elastically, but it is braided with its strands spiralling around the core so that a longitudinal pull causes it to squeeze the core, transmitting the core's elastic compression to the longitudinal extension of the sheath and cord. Specialized bungees, such as some used in bungee jumping, may be made entirely of elastic strands. Uses upA child on a bungee cord device in Moscow, Russia Bungee cords have been used to provide a lightweight suspension for aircraft undercarriages from before World War I, and are still used on many small homebuilt aircraft where weight remains critical. Bungee cords were also used in parachuting to assist in opening the old-style parachute container after the ripcord wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Jump Rope
Chinese jump rope (Chinese: 跳皮筋; pinyin: tiàopíjīn), also known as Chinese ropes, jumpsies,Block, John and Block, Tina (2013). ''It's a Hop, Skip, and Jump for Fitness and for Fun!'', p.27.

Elastic (album)
''Elastic'' is a 2002 studio album by American jazz saxophonist Joshua Redman. The album was released on September 10, 2002, by Warner Bros. label. Background The album is positioned as the Redman's first full-length record with electric instruments—after eight acoustic albums. Also, ''Elastic'' follows the self-titled CD by Yaya3, which features the same lineup: Redman with keyboardist Sam Yahel and drummer Brian Blade. The Yaya3 CD came out on Loma Records, once the R&B subsidiary of Warner Bros. The concept for Yaya3 and ''Elastic'' began when Redman started playing with Yahel and Blade at the New York's Small's club in the late 1990s. Reception David R. Adler of Allmusic wrote "Coming fast on the heels of Redman's collaborative Yaya3 date with the same players (organist Sam Yahel and drummer Brian Blade), Elastic is more about pop/soul-funk than jazz, but it doesn't sacrifice any of Yaya3's organic feeling and improvisational focus. Here Yahel plays not only Hammond organ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elasticsearch
Elasticsearch is a search engine based on the Lucene library. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Elasticsearch is developed in Java and is dual-licensed under the source-available Server Side Public License and the Elastic license, while other parts fall under the proprietary ( ''source-available'') ''Elastic License''. Official clients are available in Java, .NET ( C#), PHP, Python, Ruby and many other languages. According to the DB-Engines ranking, Elasticsearch is the most popular enterprise search engine. History Shay Banon created the precursor to Elasticsearch, called Compass, in 2004. While thinking about the third version of Compass he realized that it would be necessary to rewrite big parts of Compass to "create a scalable search solution". So he created "a solution built from the ground up to be distributed" and used a common interface, JSON over HTTP, suitable for prog ...

Amazon Elastic Compute Cloud
Amazon Elastic Compute Cloud (EC2) is a part of Amazon.com's cloud-computing platform, Amazon Web Services (AWS), that allows users to rent virtual computers on which to run their own computer applications. EC2 encourages scalable deployment of applications by providing a web service through which a user can boot an Amazon Machine Image (AMI) to configure a virtual machine, which Amazon calls an "instance", containing any software desired. A user can create, launch, and terminate server-instances as needed, paying by the second for active servershence the term "elastic". EC2 provides users with control over the geographical location of instances that allows for latency optimization and high levels of redundancy. In November 2010, Amazon switched its own retail website platform to EC2 and AWS. History Amazon announced a limited public beta test of EC2 on August 25, 2006, offering access on a first-come, first-served basis. Amazon added two new instance types (Large and Extra- ...

Elastics (orthodontics)
Elastics are rubber bands frequently used in the field of orthodontics to correct different types of malocclusions. The elastic wear is prescribed by an orthodontist or a dentist in an orthodontic treatment. The longevity of the elastic wear may vary from two weeks to several months. The elastic wear can be worn from 12 to 23 hours a day, either during the night or throughout the day depending on the requirements for each malocclusion. The many different types of elastics may produce different forces on teeth. Therefore, using elastics with specific forces is critical in achieving a good orthodontic occlusion. The term ''intermaxillary elastics'' is used when elastics can go from the maxillary to the mandibular arch. ''Intra-maxillary elastics'' are elastics used in one arch only, either mandibular or maxillary. People using elastics for orthodontic correction change their elastics three to four times during the day. Elastic wear is recommend to be used in a rectangular wire to mini ...

Elastic Collision
In physics, an elastic collision is an encounter (collision) between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise, or potential energy. During the collision of small objects, kinetic energy is first converted to potential energy associated with a repulsive or attractive force between the particles (when the particles move against this force, i.e. the angle between the force and the relative velocity is obtuse), then this potential energy is converted back to kinetic energy (when the particles move with this force, i.e. the angle between the force and the relative velocity is acute). Collisions of atoms are elastic, for example Rutherford backscattering. A useful special case of elastic collision is when the two bodies have equal mass, in which case they will simply exchange their momenta. The ''molecules''—as dist ...
