Figure Skating Rink
A figure skating rink is an ice rink designed for figure skating. Alternatively it is used for other sports such as short track speed skating, ice hockey and bandy. It is usually rectangular. Name origins ''Rink'', a Scottish word meaning 'course', was used as the name of a place where another game, curling, was played. The name has been retained for the construction of ice areas for figure skating. Basics Dimensions The size of figure skating rinks can be quite variable. The International Skating Union (ISU) prefers Olympic-sized rinks for figure skating competitions, particularly for major events. According to Rule 342 of the ISU Special Regulations & Technical Rules: Single & Pair Skating and Ice Dance 2016, an Olympic-sized figure skating rink has dimensions of by if possible, the same with an Olympic-sized short track speed skating rink and an Olympic-sized ice hockey rink, and exactly 44% larger than an Olympic-size swimming pool which has dimensions of by .

Brittleness
A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a sharp snapping sound. When used in materials science, it is generally applied to materials that fail when there is little or no plastic deformation before failure. One proof is to match the broken halves, which should fit exactly since no plastic deformation has occurred. Brittleness in different materials Polymers Mechanical characteristics of polymers can be sensitive to temperature changes near room temperatures. For example, poly(methyl methacrylate) is extremely brittle at temperature 4˚C, but experiences increased ductility with increased temperature. Amorphous polymers are polymers that can behave differently at different temperatures. They may behave like a glass at low temperatures (the gla ...

Backdrop (theater)
Theater drapes and stage curtains are large pieces of cloth that are designed to mask backstage areas of a theater from spectators. They are designed for a variety of specific purposes, moving in different ways (if at all) and constructed from various fabrics. Many are made from black or other darkly colored, light-absorbing material (In North America, for example, heavyweight velour is the current industry standard). Theater drapes represent a portion of any production's ''soft goods'', a category comprising any non-wardrobe, cloth-based element of the stage or scenery. Theater curtains are often pocketed at the bottom to hold weighty chain or to accept pipes to remove their fullness and stretch them tight. Proscenium stages use a greater variety of drapes than arena or thrust stages. In proscenium theaters, drapes are typically suspended from battens and can be controlled by a fly system (i.e., They are "flown," in theater terminology). When a drape is flown, the task of adjusti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winter Youth Olympic Games
The Youth Olympic Games (YOG) is an international multi-sport event for athletes between 15 and 18 years old, organized by the International Olympic Committee. The games are held every four years in staggered summer and winter events consistent with the current Olympic Games format, though in reverse order with Olympic Winter Games held in leap years instead of Summer Olympic Games. The first summer version was held in Singapore from 14 to 26 August 2010 while the first winter version was held in Innsbruck, Austria from 13 to 22 January 2012. The idea of such an event was introduced by Johann Rosenzopf from Austria in 1998. On 6 July 2007, International Olympic Committee (IOC) members at the 119th IOC session in Guatemala City approved the creation of a youth version of the Olympic Games, with the intention of sharing the costs of hosting the event between the IOC and the host city, whereas the travelling costs of athletes and coaches were to be paid by the IOC. These Games w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winter Olympic Games
The Winter Olympic Games (french: link=no, Jeux olympiques d'hiver) is a major international multi-sport event held once every four years for sports practiced on snow and ice. The first Winter Olympic Games, the 1924 Winter Olympics, were held in Chamonix, France. The modern Olympic Games were inspired by the ancient Olympic Games, which were held in Olympia, Greece, from the 8th century BC to the 4th century AD. Baron Pierre de Coubertin founded the International Olympic Committee (IOC) in 1894, leading to the first modern Summer Olympic Games in Athens, Greece in 1896. The IOC is the governing body of the Olympic Movement, with the Olympic Charter defining its structure and authority. The original five Winter Olympic Sports (consisting of nine disciplines) were bobsleigh, curling, ice hockey, Nordic skiing (consisting of the disciplines military patrol, cross-country skiing, Nordic combined, and ski jumping), and skating (consisting of the disciplines figure skat ...

ISU Figure Skating Championships
The International Skating Union organizes six annual Championships for figure skating. It is at the discretion of each member country which skaters, pairs or synchronized skating teams are sent to which championship. No skater in men's single skating, women's single skating, pair skating and ice dancing can compete at all four competitions in one season, but some skaters have competed at all four over the course of their careers. The Championships for men's singles, women's singles, pair skating and ice dancing are: * World Figure Skating Championships, World-level competition for senior-level skaters. * World Junior Figure Skating Championships, World-level competition for junior-level skaters. * European Figure Skating Championships, the oldest ISU Championship, open to skaters from European countries. * Four Continents Figure Skating Championships, the newest ISU Championship, open to skaters from non-European countries. The Championships for synchronized skating are held sepa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compulsory Dance
The compulsory dance (CD), now called the pattern dance, is a part of the figure skating segment of ice dance competitions in which all the competing couples perform the same standardized steps and holds to the music of a specified tempo and genre. One or more compulsory dances were usually skated as the first phase of ice dancing competitions. The 2009–10 season was the final season in which the segment was included in International Skating Union (ISU) junior and senior level competition. In June 2010, the ISU replaced the name "compulsory dance" with "pattern dance" for ice dance, and merged it into the short dance (SD) beginning in the 2010–11 figure skating season. The first CDs were developed during the 1930s by teams from Great Britain, who dominated ice dance for most of the early years after the sport was contested at the 1952 World Championships. The prominence of the CD in ice dance slowly declined, until it was removed and replaced by the SD in 2011, the year th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Dance (figure Skating)
The free dance (FD) is a segment of an ice dance competition, the second contested. It follows the rhythm dance (RD). Skaters perform "a creative dance program blending dance steps and movements expressing the character/rhythm(s) of the dance music chosen by the couple".S&P/ID 2022, p. 143 Its duration is four minutes for senior ice dancers, and 3.5 minutes for juniors. French ice dancers Gabriella Papadakis and Guillaume Cizeron hold the highest recorded international FD score of 137.09 points. Background The free dance (FD) takes place after the rhythm dance in all junior and senior ice dance competitions. The International Skating Union (ISU), the body that oversees figure skating, defines the FD as "the skating by the couple of a creative dance program blending dance steps and movements expressing the character/rhythm(s) of the dance music chosen by the couple". The FD must have combinations of new or known dance steps and movements, as well as required elements. The prog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Skating
The free skating segment of figure skating, also called the free skate and the long program, is the second of two segments of competitions, skated after the short program. Its duration, across all disciplines, is four minutes for senior skaters and teams, and three and one-half minutes for junior skaters and teams. Vocal music with lyrics is allowed for all disciplines since the 2014—2015 season. The free skating program, across all disciplines, must be well-balanced and include certain elements described and published by the International Skating Union (ISU). Overview The free skating program, also called the free skate or long program, along with the short program, is a segment of single skating, pair skating, and synchronized skating in international competitions and events for both junior and senior-level skaters.S&P/ID 2022, p. 9 The free skating program is skated after the short program. Its duration, across all disciplines, is four minutes for senior skaters and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Dance
The short dance (SD) was the first segment of an ice dancing competition from the 2010–2011 to the 2017–2018 seasons. It was approved in June 2010 by the International Skating Union (ISU). It merged the original dance (OD) and compulsory dance (CD), which were both discontinued. The ISU renamed the short dance to the rhythm dance (RD) in 2018. The SD was composed of two parts: the pattern dance (formerly known as the compulsory dance), which lasted about one minute and could be placed anywhere in the SD, and the creative section, which took up most of the SD. The pattern dance changed each year, and was announced beforehand by the ISU. The ISU also published yearly rule changes. Ice dancers were expected to perform five required elements in their SD: two segments of the pattern dance, one short lift, a step sequence, and a set of twizzles. At first, the duration of the SD was two minutes and 50 seconds; in 2016, it was changed to two minutes and 40 seconds. The firs ...

Short Program (figure Skating)
The short program of figure skating is the first of two segments of competitions, skated before the free skating program. It lasts, for both senior and junior singles and pair skaters, 2 minutes and 40 seconds. In synchronized skating, for both juniors and seniors, the short program lasts 2 minutes and 50 seconds. Vocal music with lyrics is allowed for all disciplines since the 2014-2015 season. The short program for single skaters and for pair skaters consists of seven required elements, and there are six required elements for synchronized skaters. Overview The short program, along with the free skating program, is a segment of single skating, pair skating, and synchronized skating in international competitions and events for both junior and senior-level skaters. It has been previously called the "original" or "technical" program. The short program was added to single skating in 1973, which created a three-part competition until compulsory figures were eliminated in 1990. ...

Ice Resurfacer
An ice resurfacer is a vehicle or hand-pushed device used to clean and smooth the surface of a sheet of ice, usually in an ice rink. The first ice resurfacer was developed by American inventor and engineer Frank Zamboni in 1949 in the city of Paramount, California. As such, an ice resurfacer is often referred to as a "Zamboni" as a genericized trademark. History The first ice resurfacer was invented by Frank Zamboni, who was originally in the refrigeration business. Zamboni created a plant for making ice blocks that could be used in refrigeration applications. As the demand for ice blocks waned with the spread of compressor-based refrigeration, he looked for another way to capitalize on his expertise with ice production. In 1939, Zamboni built the Iceland Skating Rink in Paramount, California. In order to resurface the skating rink, 3 or 4 workers had to scrape, wash, and squeegee the ice. A thin layer of water was then added for the fresh ice. This process was extremely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
