wax and physics?

post #1 of 11
Thread Starter 

I need to write a process description of something for a college paper. I was thinking of doing it on how skis (or wax) glide on snow. I need some information and I can't find any on the web, so could you guys give some physics or technical information on how this works? I need the information in the next day or two if possible.

Physics of Skiing

Try this book:
The Physics of Skiing: Skiing at the Triple Point
by David Lind, Scott P. Sanders

Available at Amazon.com

basically my understanding of how wax works is the wax is used to generate a controlled amount of friction between the ski base and the surface snow, creating a thin film of water which allows the ski to move. The wetter the snow the more hydrophobic the wax needs to be. Too much water and wax that is not hydrophobic enough = not ideal speed/sliding, and the opposite is true as well. Then you can get into base structures and how they affect the movement of water as well, some structures (i.e. crosshatched) will direct the water to flow out the side of the ski, while others (i.e. standard tip-to-tail) will direct the water to flow the length of the ski.

Basically, skiing is all about water, and how it moves (or allows the ski to move on it).

What Christopherstow said. Read chapter eight.
Ask Physicsman to explain triboelectric effects.

Hey funkybob, do your own homework!

First check out "A Ski Instuctor's Guide to the Physics and Biomechanics of Skiing" by Juris Vagners, PhD, Education Steering Committee, PSIA, June 1995. Check with PSIA National, they should be able to tell you where you can get it. I have a copy and can't remember where I got it from. (A little help here all you other Bears, please.)

The Cold Regions Research and Engineering Lab has a publication, CRREL Monograph 92-2 "A Review of the Processes that Control Snow Friction" by S.C. Colbeck. Sam Colbeck instrumented up a ski and did a bunch of friction tests on it. Call the CRREL Library at 603-646-4221 and they should be able to help you get a copy of it. (I was the Navy Liaison Officer at the lab in the mid 90s. If it has to do with snow and ice, these are the guys that have probably done research on it.)

Hope this gets you on a track that helps with your project.

Ok, Ok, I edited my bad spelling. I checked out "The Physics of Skiing" by Lind so I think I should be set for now. Thanks for the immediate help.

T-Square...now you have me interested.

I'm going to look into getting a copy of that paper, thanks.

As my ladyfriend puts it: I'm a cesspool of knowledge.
