Velodromes In Australia
A velodrome is an arena for track cycling. Modern velodromes feature steeply banked oval tracks, consisting of two 180-degree circular bends connected by two straights. The straights transition to the circular turn through a moderate easement curve. History The first velodromes were constructed during the late 1870s, the oldest of which is Preston Park Velodrome, Brighton, United Kingdom, built in 1877 by the British Army. Some were purpose-built just for cycling, and others were built as part of facilities for other sports; many were built around athletics tracks or other grounds and any banking was shallow. Reflecting the then-lack of international standards, sizes varied and not all were built as ovals: for example, Preston Park is long and features four straights linked by banked curves, while the Portsmouth velodrome, in Portsmouth, has a single straight linked by one long curve. Early surfaces included cinders or shale, though concrete, asphalt and tarmac later becam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schuermann
Schuermann Architects of Münster, Germany, is a dynasty of architects specialising in the design of velodromes, cycle tracks and indoor athletics tracks since 1925. The Schuermann dynasty was founded by Clemens Schuermann (1888–1956), professional track cyclist and later architect, continued by his son Herbert Schuermann (1925–1994) and his grandson Ralph Schuermann (born 1953). They have designed more than 125 cycle tracks worldwide, among them many velodromes for Olympic Games, namely in Berlin in 1936, Rome in 1960, Mexico City in 1968, Munich in 1972, Seoul in 1986, Barcelona in 1990, and Beijing in 2008. They have also designed very famous world-record tracks as the Velodromo Vigorelli in Milan, Italy; "CDOM" in Mexico City, Mexico; "Velodrom" in Berlin, Germany and The Sir Chris Hoy Velodrome in Glasgow. They also designed the track for the World-Training-Center CMC of the Union Cycliste Internationale in Aigle, Switzerland, a 200-meter wooden indoor track. Schuerm ...

Track Bicycle
A track bicycle or track bike is a bicycle optimized for racing at a velodrome or outdoor track. Unlike road bicycles, the track bike is a fixed-gear bicycle; thus, it has only a single gear ratio and has neither a freewheel nor brakes. Tires are narrow and inflated to high pressure to reduce rolling resistance. History The first bicycle race is popularly held to have been a 1,200 meter race on the 31 May 1868 at the Parc de Saint-Cloud, Paris. It was won by expatriate Englishman James Moore who rode a wooden bicycle with iron tires. The machine is now on display at the museum in Ely, Cambridgeshire, England. The Union Cycliste Internationale was founded on 14 April 1900 by Belgium, the United States, France, Italy, and Switzerland to replace the International Cycling Association, which had been formed in 1892, over a row with Great Britain as well as because of other issues. Frame design A track frame is specific to its intended use, with emphasis on rigidity and lightn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Track Stand
The track stand or standstill is a technique that bicycle riders can use to maintain balance while their bicycle remains stationary or moves only minimal distances. The technique originated in track cycling and is now used by other types of cyclists wishing to stop for a short time without putting a foot on the ground, such as bike commuters at stop signs. To perform a track stand, a cyclist holds the cranks in an approximately horizontal position with the front wheel steered to the left or right, and pedals forward, and back in the case of a fixed-gear bicycle, which the steered front wheel converts into a side-to-side motion. Origin and use The term originated from use of the technique by track cyclists prior to starting, or as a tactic in track sprinting whereby riders will initially ride very slowly and maneuver across the track in an effort to get their rival to take the lead so that they can then draft (or slipstream) behind, conserving energy for the final sprint.

Madison (cycling)
The Madison is a relay race event in track cycling, named after the first Madison Square Garden in New York, and known as the "American race" in French (''course à l'américaine'') and as ''Americana'' in Spanish and in Italian. The race The Madison is a race where each team aims to complete more laps than any of the other teams. Riders in each team take turns during the race, handing over to another team member, resting, and then returning to the race. Teams are usually of two riders but occasionally of three. Only one rider of the team is racing at any time, and the replacement rider has to be touched before taking over. The touch can also be a push, often on the shorts, or one rider hurling the other into the race by a hand-sling. How long each rider stays in the race is for the members of each team to decide. Originally, riders took stints of a couple of hours or more and the resting rider went off for a sleep or a meal. That was easier in earlier six-day races because ...

Centrifugal Force (rotating Reference Frame)
In Newtonian mechanics, the centrifugal force is an inertial force (also called a "fictitious" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It is directed away from an axis which is parallel to the axis of rotation and passing through the coordinate system's origin. If the axis of rotation passes through the coordinate system's origin, the centrifugal force is directed radially outwards from that axis. The magnitude of centrifugal force ''F'' on an object of mass ''m'' at the distance ''r'' from the origin of a frame of reference rotating with angular velocity is: F = m\omega^2 r The concept of centrifugal force can be applied in rotating devices, such as centrifuges, centrifugal pumps, centrifugal governors, and centrifugal clutches, and in centrifugal railways, planetary orbits and banked curves, when they are analyzed in a rotating coordinate system. Confusingly, the term has sometimes also been used for the reactive ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cant (road/rail)
The cant of a railway track or camber of a road (also referred to as superelevation, cross slope or cross fall) is the rate of change in elevation (height) between the two rails or edges. This is normally greater where the railway or road is curved; raising the outer rail or the outer edge of the road creates a banked turn, thus allowing vehicles to maneuver through the curve at higher speeds than would otherwise be possible were the surface flat or level. Rail On railways, cant helps a train steer around a curve, keeping the wheel flanges from touching the rails, minimizing friction, wear and rail squeal. The main functions of cant are the following: * Improve distribution of the load across both rails * Reduce wear on rails and wheels * Neutralize the effect of lateral forces * Improve passenger comfort The necessary cant in a curve depends on the expected speed of the trains and the radius. However, it may be necessary to select a compromise value at design time, for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest City Velodrome
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Cyclists On The Valley Preferred Cycling Center Track 2
Cycling, also, when on a two-wheeled bicycle, called bicycling or biking, is the use of cycles for transport, recreation, exercise or sport. People engaged in cycling are referred to as "cyclists", "bicyclists", or "bikers". Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadricycles, recumbent and similar human-powered vehicles (HPVs). Bicycles were introduced in the 19th century and now number approximately one billion worldwide. They are the principal means of transportation in many parts of the world, especially in densely populated European cities. Cycling is widely regarded as an effective and efficient mode of transportation optimal for short to moderate distances. Bicycles provide numerous possible benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ashgabat
Ashgabat or Asgabat ( tk, Aşgabat, ; fa, عشقآباد, translit='Ešqābād, formerly named Poltoratsk ( rus, Полтора́цк, p=pəltɐˈratsk) between 1919 and 1927), is the capital and the largest city of Turkmenistan. It lies between the Karakum Desert and the Kopetdag mountain range in Central Asia, near the Iran-Turkmenistan border. The city was founded in 1881 on the basis of an Ahal Teke tribal village, and made the capital of the Turkmen Soviet Socialist Republic in 1924. Much of the city was destroyed by the 1948 Ashgabat earthquake, but has since been extensively rebuilt under the rule of Saparmurat Niyazov's "White City" urban renewal project, resulting in monumental projects sheathed in costly white marble. The Soviet-era Karakum Canal runs through the city, carrying waters from the Amu Darya from east to west. Since 2019, the city has been recognized as having one of the highest costs of living in the world largely due to Turkmenistan's inflation ...
