Glide Wax
Ski wax is a material applied to the bottom of snow runners, including skis, snowboards, and toboggans, to improve their coefficient of friction performance under varying snow conditions. The two main types of wax used on skis are glide waxes and grip waxes. They address kinetic friction—to be minimized with a glide wax—and static friction—to be achieved with a grip wax. Both types of wax are designed to be matched with the varying properties of snow, including crystal type and size, and moisture content of the snow surface, which vary with temperature and the temperature history of the snow. Glide wax is selected to minimize sliding friction for both Alpine skiing, alpine and Cross-country skiing, cross-country skiing. Grip wax (also called "kick wax") provides on-snow traction for cross-country skiers, as they stride forward using Cross-country skiing#Classic, classic technique. Modern plastic materials (e.g. high-modulus polyethylene and Teflon), used on ski bases, have ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ski Warfare
Ski warfare is the use of skiing, ski-equipped troops in war. History Early Ski warfare is first recorded by the Denmark, Danish historian Saxo Grammaticus in the 13th century. During the Battle of Oslo (1161), Battle of Oslo in 1161, Norwegian troops used skis for reconnoitering. They were also used in 1452 in Sweden, and in the 15th to 17th centuries by various other Scandinavia, Scandinavian countries. Norwegian Captain Jens Emahusen wrote a military ski manual ''Skiloperegglement'' in 1733. In 1767, military ski competitions began. They evolved into the biathlon. Napoleonic Wars Denmark–Norway (though only Norwegian) ski troops were used against Sweden during the Gunboat War in the Napoleonic Wars. File:Johannes Senn og Johan F. L.
