The skiers use flat and long skies to slide on the snow, because larger the area of cross-section, the lesser is the pressure on the snow. Hence, a skier can easily slide on the snow without sinking his feet in it.
Why skiers use flat and broad skis?
The skiers use flat and broad skis to ski on the snow. The larger surface of skis reduces pressure on snow and helps them to slide instead of sinking. … The increased pressure may hurt the body of divers.
Why do the skiers use flat and long skies to slide on the snow?
Skiers use flat and long skiers to slide on snow,because the larger the area of cross-section,the lesser is the pressure on snow. noooooooooooo, not 2 reduce friction, to reduce pressure. … bcz of this the skiers can slide on snow easily as pressure decreases. if pressure was increased the skiers would sink in the snow.13 мая 2011 г.
Why are skis long and flat?
Answers and Solutions
Question: Why do skiers have long and flat boards as skis? Answer: Skiers use flattened board so that larger the surface area , lower the pressure , so that the skier slides on the snow rather than sinking in it . Also , it is long and not broad such that frction is lesser.
Why do skis have a large surface area?
A ski with a large surface area will not sink into deep snow as quickly as a ski with a small surface area, increasing manoeuvrability and momentum. … A ski with a large surface area will create less friction on the snow, increasing its acceleration and maximum speed.
Why do skiers not sink in the snow?
Skis create a large contact area between the skier and the snow. Therefore, the weight of the skier—or how much gravity pulls on him—is spread out over a larger area. The skier presses less on each square inch of snow, and instead of sinking into it he or she can glide over it.
What does sidecut mean in skis?
Sidecut. “Sidecut is the top-down silhouette of a ski,” Peruzzi says, meaning it’s how the ski tapers from the tip to the waist and then widens again from the waist to the tail, resulting in an almost hourglass shape. … The greater the difference between the ends and the middle, the deeper the sidecut.
Are stiffer skis better?
In general, a firmer-flexing ski is more stable and powerful under a strong skier; if too stiff, the ski is difficult to drive into a new turn, especially in trees, bumps and powder.
Do skis have a large surface area?
Skis have a large surface area in order to reduce the pressure on snow.
