Ski Pole
Ski poles, also referred to as poles (in North America), sticks (UK), or stocks (Australia), are used by skiing, skiers for balance and propulsion. Modern ski poles are most commonly made from Aluminium, aluminum and Carbon fibers, carbon fiber, though materials such as bamboo are still used. Poles are used in alpine skiing, freestyle skiing (with the exception of aerials), and cross-country skiing. ski jumping, Ski jumpers do not use poles. History , the earliest ski pole was found in Sweden and dates back to 3623 BC, while the earliest depiction of a man with a ski pole was found in Norway in the form of a cave painting, dated at 4000 BC. Early skiers would use this pole for the purposes of balancing, braking, and turning. Alpine societies such as those in Nordic regions or the Altai mountains used their ski poles to hunt as well, giving them spear-like qualities. Skiers began to use two ski poles in 1741. This provided greater balance than one pole could provide and made pus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carbon-fiber-reinforced Polymer
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 ...

Cross-country Skiing
Cross-country skiing is a form of skiing whereby skiers traverse snow-covered terrain without use of ski lifts or other assistance. Cross-country skiing is widely practiced as a sport and recreational activity; however, some still use it as a means of travel. Variants of cross-country skiing are adapted to a range of terrain which spans unimproved, sometimes mountainous terrain to groomed courses that are specifically designed for the sport. Modern cross-country skiing is similar to the original form of skiing, from which all skiing disciplines evolved, including alpine skiing, ski jumping and Telemark skiing. Skiers propel themselves either by striding forward (classic style) or side-to-side in a skating motion (skate skiing), aided by arms pushing on ski poles against the snow. It is practised in regions with snow-covered landscapes, including Europe, Canada, Russia, the United States, Australia and New Zealand.

Giant Slalom
Giant slalom (GS) is an alpine skiing and alpine snowboarding competitive discipline. It involves racing between sets of poles ("gates") spaced at a greater distance from each other than in Slalom skiing, slalom but less than in Super-G. Giant slalom and slalom make up the technical events in alpine ski racing. This category separates them from the speed events of Super-G and Downhill (ski competition), downhill. The technical events are normally composed of two runs, held on different courses on the same ski run. Course The vertical drop for a GS course must be for men, and for women. The number of gates in this event is 56–70 for men and 46–58 for women. The number of direction changes in a GS course equals 11–15% of the vertical drop of the course in metres, 13–18% for children. As an example, a course with a vertical drop of would have 33–45 direction changes for an adult race. Speed Although giant slalom is not the fastest event in skiing, on average a well-t ...

Slalom Skiing
Slalom is an alpine skiing and alpine snowboarding discipline, involving skiing between poles or gates. These are spaced more closely than those in giant slalom, super-G, super giant slalom and Downhill (ski competition), downhill, necessitating quicker and shorter turns. Internationally, the sport is contested at the FIS Alpine World Ski Championships, and at the Olympic Winter Games. History The term slalom comes from the Morgedal/Seljord dialect of the Norwegian language, Norwegian word "slalåm": "sla", meaning "slightly inclining hillside", and "låm", meaning "track after skis". The inventors of modern skiing classified their trails according to their difficulty: *''Slalåm'' was a trail used in Telemark by boys and girls not yet able to try themselves on the more challenging runs. *''Ufsilåm'' was a trail with one obstacle (''ufse'') like a jump, a fence, a difficult turn, a gorge, a cliff (often more than high), et cetera. *''Uvyrdslåm'' was a trail with sever ...

Drag (physics)
In fluid dynamics, drag, sometimes referred to as fluid resistance, is a force acting opposite to the direction of motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers, two solid surfaces, or between a fluid and a solid surface. Drag forces tend to decrease fluid velocity relative to the solid object in the fluid's path. Unlike other resistive forces, drag force depends on velocity. Drag force is proportional to the relative velocity for low-speed flow and is proportional to the velocity squared for high-speed flow. This distinction between low and high-speed flow is measured by the Reynolds number. Drag is instantaneously related to vorticity dynamics through the Josephson-Anderson relation. Examples Examples of drag include: * Net force, Net Aerodynamic force, aerodynamic or Fluid dynamics, hydrodynamic force: Drag acting opposite to the direction of movement of a solid object such as cars, aircraft, and boat hulls. * Viscou ...

Speed Skiing
Speed skiing is the sport of skiing downhill in a straight line at as high a speed as possible, as timed over a fixed stretch of ski slope. There are two types of contest: breaking an existing speed record or having the fastest run at a given competition. Speed skiers regularly exceed History Speed skiing dates from 1898 with a run by American Tommy Todd, reported at . Official records began with an run by Leo Gasperl in 1932. While training for the 1956 Winter Olympics, American downhiller Ralph Miller is credited with being the first to break , at nearly in August 1955 at Portillo, Chile, a record which held up for fifteen years. In 1978, also at Portillo, American Steve McKinney's record-breaking run of made him the first to break the barrier. It was a demonstration sport at the Albertville 1992 Winter Olympics on the Les Arcs speed skiing course, but was deemed too dangerous after several recorded deaths.

Downhill (ski Competition)
Downhill is a form of alpine skiing competition. Whereas the other alpine skiing events (Slalom skiing, slalom, giant slalom, Super-G, super giant slalom, and alpine skiing combined, combined) emphasize turning and technique, downhill emphasizes "the six components of technique, courage, speed, risk, physical condition and judgement", according to the International Ski Federation, FIS "International Ski Competition Rules (ICR)".. Speeds of up to are common in international competition. Athletes must have an aerodynamically efficient tuck position to minimize drag coefficient, drag and increase speed. The term, "downhill skiing", is also used as a synonym for alpine skiing as a recreational activity. History The rules for downhill skiing competitions were originally developed by Sir Arnold Lunn for the 1925 British National Ski Championships. A speed of was first achieved by Johan Clarey at the 2013 Alpine Skiing World Cup, 2013 Lauberhorn ski races, Lauberhorn FIS Alpine Sk ...

Super-G
Super giant slalom, or super-G, is a racing discipline of alpine skiing. Along with the faster downhill, it is regarded as a "speed" event, in contrast to the technical events giant slalom and slalom. It debuted as an official World Cup event during the 1983 season and was added to the official schedule of the World Championships in 1987 and the Winter Olympics in 1988. Much like downhill, a super-G course consists of widely set gates that racers must pass through. The course is set so that skiers must turn more than in downhill, though the speeds are still much higher than in giant slalom (hence the name). Each athlete only has one run to clock the best time. In the Olympics, super-G courses are usually set on the same slopes as the downhill, but with a lower starting point. History Super-G was run as a World Cup test event during the 1982 season, with two men's races and a women's race that did not count in the season standings.

Backcountry Skiing
Backcountry skiing ( US), also called off-piste (Europe), alpine touring, freeriding or out-of-area, is skiing in the backcountry on unmarked or unpatrolled areas either inside or outside a ski resort's boundaries. This contrasts with alpine skiing, which is typically done on groomed trails benefiting from a ski patrol. Unlike ski touring, backcountry skiing can – and often does – include the use of ski lifts including snowcats and helicopters. Recent improvements in equipment have increased the popularity of the sport. As the sport does confront the individual practicing it with the dangers of natural, unprepared alpine terrain like avalanches, it is generally recommended to carry standard safety equipment and to learn beforehand how to behave safely under such conditions. Terminology The terms "backcountry" and "off-piste" refer to where the skiing is being done, while terms like ski touring, ski mountaineering, telemark, freeriding, and extreme skiing describ ...
