Coxed Pairs
A coxed pair is a rowing boat used in the sport of competitive rowing. It is designed for two persons who propel the boat with sweep oars and is steered by a coxswain. The crew consists of two rowers, each having one oar, and a cox. One rower is on the stroke side (rower's right hand side) and other is on the bow side (rower's lefthand side). The cox steers the boat using a rudder and may be seated at the stern of the boat where there is a view of the crew or in the bow (known as a bowloader). With a bowloader, amplification is needed to communicate with the crew which is sitting behind, but the cox has a better view of the course and the weight distribution may help the boat go faster. When there is no cox, the boat is referred to as a "coxless pair". Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to reduce drag to a minimum. Originally made from wood, shells are now almost always made from a composite m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weight Distribution
Weight distribution is the apportioning of weight within a vehicle, especially cars, airplanes An airplane or aeroplane (informally plane) is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectr ..., and trains. Typically, it is written in the form ''x''/''y'', where ''x'' is the percentage of weight in the front, and ''y'' is the percentage in the back. In a vehicle which relies on gravity in some way, weight distribution directly affects a variety of vehicle characteristics, including car handling, handling, acceleration, traction (engineering), traction, and component life. For this reason weight distribution varies with the vehicle's intended usage. For example, a Drag racing, drag car maximizes traction at the rear axle while countering the reactionary pitch-up torque. It generates this counter-torque by placing a small amount ...

Rowing At The Summer Olympics
Rowing at the Summer Olympics has been part of the competition since its debut in the 1900 Summer Olympics. Rowing was on the program at the 1896 Summer Olympics but was cancelled due to bad weather. Only men were allowed to compete until the women's events were introduced at the 1976 Summer Olympics in Montreal which gave national federations the incentive to support women's events and catalysed growth in women's rowing. Lightweight rowing events (which have weight-limited crews) were introduced to the games in 1996. Qualifying for the rowing events is under the jurisdiction of the World Rowing Federation. World Rowing predates the modern Olympics and was the first international sport federation to join the modern Olympic movement. Summary Events At the 2016 and other recent Olympics, the following 14 events were contested: *Men: Single sculls, Double sculls, Quadruple sculls, Coxless pair, Coxless four, Eight. *Lightweight Men: Double sculls, Coxless four *Women: Sing ...

Olympic Games
The modern Olympic Games or Olympics (french: link=no, Jeux olympiques) are the leading international sporting events featuring summer and winter sports competitions in which thousands of athletes from around the world participate in a variety of competitions. The Olympic Games are considered the world's foremost sports competition with more than 200 teams, representing sovereign states and territories, participating. The Olympic Games are normally held every four years, and since 1994, have alternated between the Summer and Winter Olympics every two years during the four-year period. Their creation was inspired by the ancient Olympic Games (), 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 Games in Athens in 1896. The IOC is the governing body of the Olympic Movement (which encompasses all entities and individuals involved in the Oly ...

International Rowing Federation
World Rowing, also known as the World Rowing Federation (former abbreviation FISA; french: Fédération internationale des sociétés d'aviron), is the international governing body for rowing. Its current president is Jean-Christophe Rolland who succeeded Denis Oswald at a ceremony held in Lucerne in July 2014. The World Rowing Cup, World Rowing Championships, and other such competitions are overseen by this organization. History General It was founded by rowing representatives from France, Switzerland, Belgium, Adriatica, and Italy on 25 June 1892 in Turin in response to the growing popularity of the sport of rowing, and the consequent need for uniformity of regulations over such matters as race lengths, boat composition, and weight classes. Also, at the time, betting on rowing was very popular, and the rowers or coaches were themselves often taking bets. Amateur status, whilst widespread in England and elsewhere, was unknown in the sport in many nations, a state of affairs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outriggers
An outrigger is a projecting structure on a boat, with specific meaning depending on types of vessel. Outriggers may also refer to legs on a wheeled vehicle that are folded out when it needs stabilization, for example on a crane that lifts heavy loads. Powered vessels and sailboats An outrigger describes any contraposing float rigging beyond the side (gunwale) of a boat to improve the vessel's stability. If a single outrigger is used it is usually but not always windward. The technology was originally developed by the Austronesian people. There are two main types of boats with outriggers: double outriggers (prevalent in maritime Southeast Asia) and single outriggers (prevalent in Madagascar, Melanesia, Micronesia and Polynesia). Multihull ships are also derived from outrigger boats. In an outrigger canoe and in sailboats such as the proa, an outrigger is a thin, long, solid, hull used to stabilise an inherently unstable main hull. The outrigger is positioned rigidly and ...

Carbon-fibre Reinforced Plastic
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other ad ...

Composite Material
A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Typical engineered composite materials include: *Reinforced concrete and masonry *Composite wood such as plywood *Reinforced plastics, such as fibre-reinforced polymer or fiberglass *Ceramic matrix composites ( composite ceramic and metal matrices) *Metal matrix composites *and other advanced composite materials There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...

Racing Shell
In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ''shell'') is an extremely narrow, and often comparatively long, rowing boat specifically designed for racing or exercise. It is outfitted with long oars, outriggers to hold the oarlocks away from the boat, and sliding seats. The boat's long length and semicircular cross-section reduce drag to a minimum. This makes the boat both fast and unstable. It must be balanced by the rowers to avoid tipping. Being able to balance – or "set" – the boat while putting maximum effort into the oars is therefore an essential skill of sport rowing. History The racing shell evolved from the simple working rowboat. Boats with longer hulls and narrower in beam were developed in the early 19th century specifically for team racing. These dedicated boats were the first boats that could be called racing shells, and they evolved into the highly specialized forms used today. Riggers A narrower boat provides a sharper ...

Coxless Pair
A coxless pair is a rowing boat used in the sport of competitive rowing. It is designed for two rowers, who propel the boat with sweep oars. The crew consists of a pair of rowers, each having one oar, one on the stroke side (rower's right hand side) and one on the bow side (rower's lefthand side). As the name suggests, there is no coxswain on such a boat, and the two rowers must co-ordinate steering and the proper timing of oar strokes between themselves or by means of a steering installation which is operated by foot from one of the rowers. The equivalent boat when it is steered by a cox is referred to as a "coxed pair". Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to reduce drag to a minimum. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and weight advantages. Pairs have a fin towards the rear, to help prevent ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
