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 the 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. The oldest surviving regular velodrome two-straight oval tracks is from 1889, located ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Cycling
Track cycling is a Cycle sport, bicycle racing sport usually held on specially built banked tracks or velodromes using purpose-designed track bicycles. History Track cycling has been around since at least 1870. When track cycling was in its infancy, it was held on velodromes similar to the ones used today. These velodromes consisted of two straights and slightly banked turns, though they varied more in length and material than the modern 250 m track. One appeal of indoor track racing was that spectators could be easily controlled, and hence an entrance fee could be charged, making track racing a lucrative sport. Early track races attracted crowds of up to 2,000 people. Indoor tracks also enabled year-round cycling for the first time. The main early centers for track racing in Britain were Birmingham, Sheffield, Liverpool, Manchester and London. The most noticeable changes in over a century of track cycling have concerned the bikes themselves, engineered to be lighter and more ...

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. Bicycle tire, 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 (cyclist), James Moore who rode a wooden bicycle with iron bicycle tire, tires. The machine is now on display at the museum in Ely, Cambridgeshire, 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.

Forest City Velodrome
A forest is an ecosystem characterized by a dense community of 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'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the tropical latitudes. The next largest share of forests are found in subarctic climates, followed by temperate, and subtrop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Stand
The track stand or standstill is a technique that bicycle Cycling, 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 cycling, track cyclists prior to starting, or as a tactic in Sprint (cycling), 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 Drafting (aerodynamics), draft (or ...

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 in which the team which completes the most laps wins. Tied positions are split by points awarded for placings at a series of sprints at intervals during the race. Teams usually have two riders but occasionally three. Riders in each team take turns, with only one rider per team racing at any time. After resting, riders can return to the race. To take over, the replacement rider has to be touched, pushed, often on the shorts, or hurled by the departing team member by a hand-sling. How long each rider stays in the race is for the rider's team to decide. Originally, riders took stints of several hours and the resting rider could sleep or have a meal. That was easier in earlier six-day races because hours could pass witho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifugal Force (rotating Reference Frame)
Centrifugal force is a fictitious force in Newtonian mechanics (also called an "inertial" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It appears to be directed radially away from the axis of rotation of the frame. The magnitude of the centrifugal force ''F'' on an object of mass ''m'' at the perpendicular distance ''ρ'' from the axis of a rotating frame of reference with angular velocity is F = m\omega^2 \rho. This fictitious force is often applied to 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 non–inertial reference frame such as a rotating coordinate system. The term has sometimes also been used for the '' reactive centrifugal force'', a real frame-independent Newtonian force that exists as a reaction to a centripetal force in some scenarios.

Cant (road/rail)
The cant of a Rail transport, railway track or camber angle, 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 of the road. 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 travel round the curve at greater speeds than would be possible if the surface were level. Rail Superelevation in railway tracks ;Importance of superelevation In curved railway tracks, the outer rail is elevated, providing a banked turn. This allows trains to navigate curves at higher speeds and reduces the pressure of the wheel flanges against the rails, minimizing friction and wear. The difference in elevation between the outer and inner rails is referred to as cant in most countries. ;How superelevation works The main functions of cant are the following: * Improve distribution of th ...
