Ski geometry is the shape of the ski. Described in the direction of travel, the front of the ski, typically pointed or rounded, is the tip, the middle is the waist and the rear is the tail. Skis have four aspects that define their basic performance: length, width, sidecut and camber. Skis also differ in more minor ways to address certain niche ...
The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt".
Slope angle (Φ) is the angle measured from the horizontal to the plane of a slope with a clinometer. Aspect of slope (AS) is the compass direction towards which a slope faces, normal to the contours of elevation, given either degrees from true North N = 0° = 360° or as N, NE, E, SE, S, SW, W, NW.
A piste (/ p iː s t /) [1] is a marked ski run or path down a mountain for snow skiing, snowboarding, or other mountain sports. This European term is French [2] ("trail", "track") and synonymous with 'trail', 'slope', or 'run' in North America. The word is pronounced using a long "e" sound so that it rhymes with "beast".
A 100% slope is a 45-degree angle. In general, beginner slopes (green circle) are between 6% and 25%. Intermediate slopes (blue square) are between 25% and 40%. Difficult slopes (black diamond) are 40% and up. Although slope gradient is the primary consideration in assigning a trail difficulty rating, other factors come into play.
A type of ski or snowboard that is designed to be the jack of all trades and suitable for any terrain or style of skiing or snowboarding. From groomed runs and snowpark to powder and backcountry lines, with all-mountain skis or snowboard you’re ready for anything. [1] alpine skiing. Also called downhill skiing.
A ski jumping hill is a sports venue used for ski jumping. They vary in size from temporary handmade snow structures to permanent competition venues. At the top is an in-run where the jumper runs down to generate sufficient speed, before reaching the jump. The skier is then airborne until landing on the landing slope.
Two ski tracks with different degrees of sinuosity on the same slope Sinuosity , sinuosity index , or sinuosity coefficient of a continuously differentiable curve having at least one inflection point is the ratio of the curvilinear length (along the curve) and the Euclidean distance ( straight line ) between the end points of the curve.
