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.

longer poles feel heavier because the center of mass becomes farther from your hand, requiring more torque to accelerate the center of mass forward.....its either that or a "hand control" issue in your head.
So if I want to make them lighter I need to grab them in the middle? ;)

correct. either hold your poles in the center or only use very short poles. but if you want to reduce the coefficient of drag on your poles, you can: 1) only ski at very high altitudes 2) hammer the shafts into ovals

Not sure how that's meant... Anyway, Sarte nails how trolls argue, long before there was an Internet. There's no point engaging with them honestly, because they're uninterested in honesty. If moderators won't block them, best not to feed the trolls.
The last thing I remember being posted by our moderator is that he was giving up social media or the internet, so I wouldn't expect anything there. I don't think things got too out of control and have moderated on their own. I don't have any ill feelings towards anyone and hope the grimsurfer sticks around.

Great post!
One thing I like about this forum is that there's at least two elements at work.
One is the "Hard" side -- Facts, advice, details, tips, ...
But the other is the "Soft" side -- Social interaction, communication skills, boundaries -- it's basically an adult version of a kindergarten sandbox.

There's a kid in there in all of us.
But, I'm a bit weird, so who knows...

:lol:

And while I'm at it, I think discouraging @mikael.oh from remaining active here is our lose.

He was definitely outside the norm, but harmless and his posts interested at least some of us.
I wish him well whatever he is up to.

this forum eats its young. but if you hang around long enough you learn its mostly barking and very little biting.

TBH, I lost a lot of interest after the responses to this post:

viewtopic.php?f=1&t=5438&start=80#p54762

Folks don’t agree with my views (which were really never mine in the first place) on physics? OK. Fine. I can accept that…

Railing against a request for real world data to be collected by an impartial forum member qualified to collect it seems to be something else altogether.

Over to the OP, @Nitram Tocrut to make sense of all this. I can’t.
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.

@GrimSurfer I just wanted to clarify that I was not really the OP. My only goal was to concentrate the discussion in a specific thread and I did not want to take part of this discussion but you mentioned my name many times so I had to intervene ;) I have no intention to judge anyone. You said you lost interest after your request to Tom and I can understand but I personally would not stop participating in that forum for this sole reason. But this is up to you.

Dont take it the hard way man! I appreciate you, but have just been trying to tell the data has already been collected. Not sure if the message has gotten through :)

The data hasn’t been collected. Only the pressure at the binding. That’s the only thing Tom measured.

It is conjecture on anyones part what exact pressure will be on the tip. Why? Because the boot binding pivots on the balance point of the ski. The fulcrum is not under the ski.

Once the pressure on the tip is measured, then the same test should be repeated with a skier in the boot and applying pressure to achieve the same ~3” angle. The pressure reading from that test will then confirm whether, indeed, there is a significant pressure difference imposed by a stiffer flexor when subjected to the pressure of a skier’s foot..

There is no legitimate reason for anyone to waive their hands and say all of this has been done. It hasn’t been done.

You, and others have accused me of relying on theory. When I propose a *complete* practical test, you object to that by preferring to invoke closure based on incomplete information.

I simply don’t understand this behaviour. It is childish and obstructionist, serving no practical purpose. It doesn’t advance knowledge of skiing.
