Why do not we skiers sink in the fresh snow?
We do not sink because the skis have a high surface area compared to our feet, therefore we would float on fresh snow.
What are the average dimensions of downhill skis and how fast do they go?
I would say that a ski can easily reach 40-50 mph if one's advanced enough and using long skis and going straight down paralel. Demensions? My skis are for moderate skill levels and they are 151 cm, but racing skis can get up to 210 cm. Width depends on the brand. Probably about 4 inches.
What are alpine snow skis made of?
Wood and fiberglass are the most common for the core but you can also have carbon fiber, the edges are made of metal, modern day skis are carbon steel but older skis can have chrome type, such as those used in cutlery. Thetopsheet, graphics and bases are made out of various kinds of plastics.
What is the name of a long narrow footwear for snow travel?
That could be cross country skis.
Why does wax help ski?
it helps your skis glide over the snow and reduces friction!
Do skis increase or decrease pressure?
they decrease pressure
What does kids cross country skis do?
Kids cross country skis are specifically designed to carefully balance the weight of children and to balance it across the skis. This is to protect children and ensure safety.
What purpose was ski boots originally designed for?
To use with skis. That's why they are called ski boots.
What are some man made tools that use the principles involve low and high pressure?
There are many items that have principles of high and low pressure. Unfortunately, google doesn't really seem to understand similar questions I have been asking for my own physics homework, so the answer is just my own knowledge. High pressure examples are knives and spikes. Sharp knives have small area, but if the right amount of pressure (high) is exerted, a colossal force acts over a small area. This is the cause of high pressure. Spikes on a runners boots are pushed into the hard track by the runners weight and thus stop the runner slipping on the track because of the high pressure. Low pressure is in things like skis and flat soles. Low pressure in manufactured by a force acting over an area larger than it (it being the force). Low pressure is necessary in skiing so that the person skiing does not sink in the soft snow. It is partially as a flat sole, except a flat sole is more designed for trekking in mud.
Why do skis have a larger surface area?
The larger the surface area the more pressure can be spread out, therefore it is less likely to fall through the snow. As pressure = f / a.
What is the best way to store downhill skis?
When you store downhill skis over a long period you should put a storage wax on. This is a special wax designed to keep the bases from drying out and cracking. A good place to store your skis would be a place that is cool and has a medium humidity. Too dry will dry out your skis. Dark is also good as bright sunlight can damage the graphics and will make the temperature rise and fall which will also damage your skis.
Who exerts more pressure on the ground a women standing in running shoes a women standing in skis or a women standing in high heel shoes?
assuming they all weigh the same, they would be equal. if not, the heavier one would be exerting more pressure on the ground. if you are looking for an answer relating to pressure exerted in a specific spot, calculate it by surface area.
About how much do cross country skis go for online?
The price of cross country skis varies depending on size (youth or adult). The prices range from about $80 for junior size up to a few hundred dollars for an adult pair of cross country skis. This will give you a general idea: http://www.nextag.com/cross_-_country-skis/stores-html
When ski bags say single ski do they mean just for 1 ski?
They mean that the bag is designed to hold a single pairof skis.
Difference between men's and women's alpine skis?
Women's skis have the waist and binding farther forward compared to men's skis to compensate for women's lower centers of gravity and added weight in the rear. Because of lower weights and lower centers of gravity, women's skis also tend to be more flexible for proper turning. Women's skis are also more dramatically curvy than men's skis to make the ski turn better. On straight skis, man or woman, the rule is, "as tall as you or slightly shorter if you're a beginner, a foot taller if you're advanced or just really good." Longer skis can be dangerous, so you need to know what you're doing. On modern shaped or parabolic skis, beginner skis are around chin-height while advanced skiers may have skis up to their forehead or as tall as the skier. Shorter skis are good for beginners as they give more control and better turning. Longer skis get more speed.
Why your feet dont sink when you wear skis?
If your ski shoes are inserted into skis, then you have the whole surface area of the ski supporting your weight. The larger the surface area that is pressing down on the snow, the less pressure there is per square inch. It takes a certain amount of pressure per square inch to overcome the cohesion of the snow.
How to you say skis in french?
"Les skis."
