Physics debate

This is the World Famous TelemarkTalk / TelemarkTips Forum, by far the most dynamic telemark and backcountry skiing discussion board on the world wide web. We have fun here, come on in and be a part of it.

Ok @GrimSurfer I have a question that I intend as a yes or no question. Would you please oblige me with an answer in this fashion?

When the skier flexes the boot and loads the spring cable, does that cable transmit a force?
I don’t think it does.
Ok, not exactly yes or no but I will gladly take it :lol: . Thanks

Look up Hooke’s law Grim. You’ll find it interesting.

Edit: Its principle applies to nnn-bc flexors and shoe soles (both 75mm and nnn-bc) as well. You expend energy to flex it, generating a latent force in the elastic material.

The interesting thing is that Hooke’s Law seems to be applied to springs carrying a free mass. Sure, the spring is in tension. But both points of the spring are not fixed.

Though I do get your point about what’s going on up to the point until forces reach an equilibrium.
We dreamed of riding waves of air, water, snow, and energy for centuries. When the conditions were right, the things we needed to achieve this came into being. Every idea man has ever had up to that point about time and space were changed. And it keeps on changing whenever we dream. Bio mechanical jazz, man.

On the contrary, its a core principle in physics and used to estimate forces exerted by all sorts of elastic materials within various engineering disciplines as a function of the material's elasticity (k) upon extension or compression. Look it up :)

the first Law of Telemark skiing: the more words needed to explain a physics concept applied to telemark skiing...the less it actually matters to the common practitioner.

Maybe I misunderstand, but from the above, I think @GrimSurfer thinks the cable does not allow the skier to apply more weight / pressure to the front of the ski than the skier would be able to apply without the cable?

@GrimSurfer, does an Alpine type binding allow a skier to apply additional pressure / force to the front of the ski by leaning against the resistance of the locked down heel?
I think you will say “Yes” to this.
In the same way, a skier using a cable binding, which also creates resistance to raising the heel, does the same thing, but to a lesser degree.
Yes or no?

Or maybe you’re just explaining. Just saying…

I know popular culture loves the banal… a picture of an nth pair of skis (which we can find a better photo of on the manufacturer’s web site), a photo of a steep hill, a hero shot taken just before an utter fail.

That’s what Instagram is for (or Twitter for the modern day bard who loses their train of thought at 144 characters).
