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 ...
A ski binding is a device that connects a ski boot to the ski. Before the 1933 invention of ski lifts, skiers went uphill and down and cross-country on the same gear. As ski lifts became more prevalent, skis—and their bindings—became increasingly specialized, differentiated between alpine (downhill) and Nordic (cross-country, Telemark, and ...
A typical "universal" ski boot of the leather era. This example, by G. H. Bass, includes an indentation around the heel where the cable binding would fit, and a metal plate at the toe for a Saf-Ski release binding. The leather strap is a "long thong", used by downhill skiers to offer some level of lateral control.
Bindings: Should be reliable, light, and durable. [11] Boots: Should be light and flexible. [11] Skis: Width: 60-90 mm to balance performance and weight. Skinnier skis lack performance in softer snow but are lighter while wider skis lack performance in firmer snow and are heavier. Lightweight skis make ascent easier.
License compatibility is a legal framework that allows for pieces of software with different software licenses to be distributed together. The need for such a framework arises because the different licenses can contain contradictory requirements, rendering it impossible to legally combine source code from separately-licensed software in order to create and publish a new program.
The concrete effect of strong vs. weak copyleft has yet to be tested in court. [26] Free-software licenses that use "weak" copyleft include the GNU Lesser General Public License and the Mozilla Public License. The GNU General Public License is an example of a license implementing strong copyleft.
Copyleft is a type of free license that mandates derivative works to be licensed. The other types of free license lack this requirement: for permissive licenses, attribution is typically the only requirement, and public-domain-equivalent licenses have no restrictions.
The tension-release setting which determines the amount of force required for a ski binding to release from the skier's boot during a fall or impact. DIN is an acronym for the German Deutsche Institut für Normung. downhill downhill ski The lower ski (i.e. lower on the hill than the uphill ski) or the one that will become the lower ski during a ...
