Scale

Scales with special uses are often named after the person who invented them. Skiboards tend to vibrate when skiing on the flat bottom part of the ski and thus it is necessary to ski on the edge of the ski in order to decrease the vibration and have more control of the ski. Scale can refer to:. The Line ski company has manufactured ski boards since the mid 1990s and is credited with the creation of the first modern, twin tip ski board. . The Bigfoot ski was popular during the late 80s and early 90s. Time scales: Historical periods, Geologic periods. Before this time period the Bigfoot ski company produced a short, foot shaped ski called the Bigfoot.

Hierarchy. The Snowblade name was originally marketed by ski company Salomon during a short ski fad in the mid 1990s. Chain of being. Skiboard bindings are mounted closer to the center of the ski, typically do not have a DIN style binding, and require an ankle leash due to the absence of a braking system. The Torino Scale and the Palermo scale measure the impact hazard level of near-Earth objects such as asteroids. Skiboards, often incorrectly called snowblades, are short skis, typically 90-130cm, marketed towards children, teens, and adults as a fun, accessory snow toy. The Fujita scale estimates the intensity of tornadoes. Long and wide skis, with bindings attaching at the toe.

The Glasgow Coma Scale measures the severity of comas. Skis for ski jumping. The Scoville Scale measures the hotness of peppers. This is also the model used by military forces trained to fight in winter conditions, and the most closely related to the historical ski. The Goldberg scale measures mania and depression. These are characteristically quite wide, and with cable bindings to provide general sturdyness, and to better extract ones feet from deep snowbanks, in case it should be impossible to reach the bindings by hand. The Celsius, Fahrenheit, and Kelvin scales (among others) measure temperature. Skis for mountain/backcountry/cross-country free range skiing which are designed for skiing on unbroken snow, where an established track is lacking.

The Beaufort scale is used to measure wind force. Skating is also the technique used in biathlons. The Richter scale, the Mercalli scale, the Rossi-Forel scale and the Omori are all used to measure the intensity of earthquakes. Skating skis are shorter than classical skis and do not need grip wax. Social stratification, socioeconomic class. There are two major techniques, classical (traditional striding) and freestyle or skating which was developed in the 1980s. Kinsey scale, sexual orientation (Klein scale is superior but not yet as well known). Some waxless models may have patterns on the bottom to increase the friction when the ski slides backward.

Likert scale, questionnaire format. The ski bases are waxed to reduce friction during forward motion, and kick wax can also be applied to get adhesion when going uphill. Scale (social sciences). There are three binding systems currently used, Rottefella's NNN and Salomon's SNS profil and SNS pilot. European Macroseismic Scale, Japan Meteorological Agency seismic intensity scale, Mercalli Intensity Scale, Moment magnitude scale, Richter magnitude scale. The boots attach to the bindings at the toes only. 2 mm scale, HO scale, O scale. Cross-country skis are very light and narrow, and usually have quite straight edges, though some newer skis have slight sidecut.

Scale model. The fact that the foot is only attached to the ski at the toes, means that specialised more flexible ski boots are used, and a specific turning technique involving pushing one foot forward and lifting the heel of the other foot is used. Bohlen-Pierce scale, chromatic scale, Deutsch's scale illusion, diminished scale, mathematics of musical scales, minor scale. It was pioneered by Sondre Norheim of Telemark, Norway. Scale (music). The Telemark ski was the first ski with an inwards-turned waist which made it much easier for skiers to turn. Resource-Based Relative Value Scale, returns to scale. A downhill or touring ski, where the binding attaches only at the toe.

Scale (economics). Telemark ski. Allred-Rochow scale, Mulliken scale, Pauling scale. Due to its extra width and flotation in deep snow enthusiasts claim it superior as a powder ski. Hounsfield scale (radiodensity). The monoski is produced by only half a dozen companies world-wide in limited quantities. Mulliken scale electronegativity. More common in use during a brief boom in the 80s today the monoski is used by only a few thousand enthusiasts world-wide.

Kelvin scale measures Thermodynamic temperature. The monoski is a single, double-width ski that attaches by a common DIN binding interface to modern front entry boots. Solar flare energy intensity. The ski is used with alpine touring boots which are hard but lighter than downhill skiing boots. Torino Scale. For skiing downhill the bindings are locked. Palermo Technical Impact Hazard Scale. For climbing of steep slopes, skins (originally made from the fur of seals, but now made of synthetic materials) can be attached at the base of the ski and the binding opened at the heel.

Large-scale structure of the cosmos. Like the backcountry ski it is designed for unbroken snow. Scale factor (Universe). This type of ski is ususally a modified light-weight downhill ski with an alpine touring binding. Atmospheric sciences: Celsius scale, Fahrenheit scale, Kelvin scale, Saffir-Simpson Hurricane Scale, Fujita scale (tornadoes), Beaufort scale (wind). Alpine ski touring ski. Geosciences: Mohs scale of mineral hardness. The first company to successfully market a twin-tip ski was Salomon, with their 1080 ski.

Zoology: Scale insect, plant parasites which resemble animal scales. The first twin-tip ski was the K2 Poacher, but they did not sell well. Zadok scale cereal development. Line Skis, started by Jason Levinthal, is the first company to market only twin-tip skis. Weighing scale - used for measurement of weight (mass or force). Once considered a passing fad, twin-tip skis have become a staple ski in the product line of all major ski-producing companies worldwide, with a few speciailizing in only twin tips. Engineer's scale. In the past five years twin tips have become popular among youth skiers, ages 14-21.

Architect's scale - (or draughtsman's scale) is a ruler-like device, which facilitates the production of technical drawings. The popularity explosion of twin-tip skis created a push for the inclusion of more terrain park elements at ski areas across the globe. Duration scale. Bindings are typically mounted closer to the center of the ski to facilitate the balance of fore and aft pressure, while skiing backwards or "switch", bindings are built lower to the ski for easy rail sliding. Scale factor. Twin-tip skis are generally wider at the tip, tail, and underfoot and constructed of softer materials to cushion landings. Order of magnitude. The turned-up tail allows less application of aft pressure on the ski, causing it to release from a turn earlier than a non-twin-tip ski.

Logarithmic scale, mathematics. Twin-tip skis make it easier to ski with one's back facing downhill, allowing reversed take-offs and landings when performing aerial maneuvers. Scale (temperature). Twin-tip skis, also known as "freestyle skis", are skis with turned-up ends at both the front and rear. Scale (zoology). The ski is turned by applying a mixture of pressure, rotation and edge angle. Scale (spatial). Modern bindings utilize a DIN spring system to minimize the amount of force applied to joints such as the knee during backward twisting falls.

Scale (ratio). As a safety feature, it is spring-loaded, detaching the ski from the foot in case excessive force is applied. Scale (map). The ski binding anchors the foot firmly to the ski at heel and toe. Scale (computing). Such skis were once termed carving skis, or shaped skis or parabolic skis to differentiate them from the more traditional straighter skis, but nearly all modern skis have this more pronounced shape now. Faced by competition from snowboarding, during the 1990s this shaping of the ski became significantly more pronounced to make it both easier for skiers to carve turns, and to dramatically increase the turning sensation experienced.

By setting the ski at an angle so that the edge cuts into the snow, the ski will follow the arc and hence turn the skier, a practice known as carving a turn. Most varieties of skis have a metal edge running the length of the sides that once sharpened allow the ski to grip more effectively on hard packed snow and ice. Downhill skis are "shaped" (when viewed from above or below, the center or "waist" is narrower than the tip or tail, and the cut from tip through waist to tail follows either a parabolic curve, or an arc, on either side of the ski) to promote easy turning. Many types of skis exist, all designed for use different situations, of which the following are a selection.

Second, it forces the consumer to purchase both skis and bindings from the same manufacturer, increasing profits. First, they often use a railroad track style design, to allow the toe and heel pieces to slide, which in turn allows the ski to flex deeply, without a flat-spot underfoot, caused by the presence of a binding. Beginning in the early 2000's, many ski manufaturers began designing their skis and bindings together, creating an 'integrated binding system.' These systems serve two purposes. The user is attached by bindings which in turn hold the ski boots.

Most skis are long and thin, pointed and curved upwards at the front to prevent it from digging into the snow. They are now usually made from a complex assembly of components including glass fiber, Kevlar, Titanium or composite materials, though many may still contain a wooden core. Skis were originally wooden planks made from a single piece of wood. .

Ski wax is used to increase the freezing point of water on the base of the ski, easing the creation of the water layer. This is why if there is freezing rain that freezes to the bottom of the ski (perhaps when carrying the ski), when set down on the snow, won't glide until the ice wears off or is knocked off. This creates a very thin layer of water directly under the ski upon which the ski glides. Snow skis glide on snow because downward pressure, as well as heat from surface friction, melts the snow directly under the ski.

Also, a ski may denote a similar device used for other purposes than skiing, e.g., for steering snowmobiles. Originally intended as an aid to travel in snowy regions, they are now primarily used for recreational and sporting purposes. A ski is a long flat device worn on the feet designed to help the wearer slide over snow.
