We've also done centrifugal force as one force that must be included on objects in an accelerating frame of reference so that the net force acting on the skier F=ma =0 when the frame of reference is attached to the skier. Do a search.
No, but I have a time stamped video tape, google earth, and pretty good maping skillz.

This is regardng the superstar carving clip.

I can post the screen caps as proof, but here are the numbers:

Total point to point distance of clip (from a stop, to the crossover trail, past the camera): ~1200 feet
Time to cover that distance: ~30 sec.
Average speed (point to point): 40 Ft/sec or 27.3 mph

Now, I'm not skiing in a straight line, and we should probably just look at the last 8 turns before the camera, going back from the vidcap we're discussing. 8 turns back is where I come over a slight roll and pass a lift tower. From that point, to where I am in the vidcap, is around 630-650 feet. I drop about 210 vertical feet in that time, and the pitch is averaging 18 degrees. I cover that in 13 secs. So:

Bottom 8 turns: 640 feet
Time to cover distance: 13 seconds
Average speed (point to point): 49.2 ft/sec, or 33.5 mph.

Now, I'm not going in a straight line, am I? I'm making turns that cover, on average, 80 feet down the fall line (~640 ft/8 turns). I probably go 10 feet down the fall line on each transition, so I go around 70 feet down the fal line on each arc of the carve. Assuming those are 90 degree turns, averaging a roughly circular arc shape, the radius is around 49.5 feet or, 15 meters. Am I bending the ski? Well yeah, pretty well I would think so considering it's a 22m radius ski.

How much linear distance do I cover, and what's my real average speed (not point to point)? Well, 10 feet down the fall line, at 45 degrees to the fall line, is around 14.2 feet. Times 8 transitions, is ~113 feet. Each 90 degree, 49.5ft radius arc covers around 77.8 feet distance, times 8, is around 622 feet. So....total distance covered is around 735 feet. Covered in 13 seconds....or at 56.5 ft/sec, or 38.5 mph.

So, what's that mean? Well, it means I'm skiing a bit slower than WC gs, but it also means I can make an accurate off the cuff the speed estimate - I said on page 1 or 2 that I thought I was going 35+ mph in this clip. If you take all these figures and put them into the calculator above, you get the rough result that the centripetal force generated HAS TO BE approximately double the mass in the system.

R: 15m
Velocity: 56.5 ft/sec
Body weight: x
Centripetal force: ~2x

Now what? I weigh about 210lb with clothes and gear in that vid. I have to generate a 420 lb centripetal force to make the turn shape as described. If I have 30 lb (about 15%) vertically supported on my inside ski, that leaves me with 180 lb body weight/mass to work with. This center of mass has to be applied at a ~67 degree angle from vertical, to get the required 420 lbs centripetal force.

So yes, I am achieving the correct angulation for the turn shape and speed, it is NOT excessive........especially considering I'm on a fatter ski with some torsional flex, around a 2-3 degree base bevel, and not on race boots.
Wow. You are a freakin' tool.
U.P. Could you paraphrase that? I don't think you were concise enough.

I'll Second that, though!

That's the type of edge angle I need to hit to get that turn radius out of those skis. I could ski slower, with small radius skis, and lower edge angles.......and still get those turn shapes. But I'm not.
So for that turn shape, at that speed, on that particular run, on that particular day, using those particular skis.....

THAT was the ideal way to ski it???

Huh..:
I'm not sure you could ski slower, with lower edge angles.
While I am at my lousy sympatico wireless, I'm not going to review the vid again. You are no doubt more familiar with it than I am. Still I suggest you reevaluate a couple of assumptions. (btw the mass cancels out)

They didn't look anywhere close to 90 degrees to me, but maybe I'm misremembering.

Not too sure about this. It may be tht you are doing longer radii, and linking them together before you turn a full 90 degrees (90 degrees is what you were doing on the manky trail). Maybe 18 m

Let's pretend it's 30 mph.

at 30mph and 18m radius you would be pulling 1 g, and need a 45 degree angle.

It may be that you are going faster and turning tighter and just need someplace to put your leg. However it is more likely that you have more weight on that leg than you think you do. In any event you should endeavour to position the leg properly parallel to the other one, and let the ski carve.

You mean people on the internet who didn't tell you that you were a good skier? If that was your opinion, explain to us why you bothered asking people here to evaluate your skiing in the first place when you didn't actually want anyone to tell you the truth... It is clear that you need professional help; and I don't mean a WC coach.

Tai Chi Skier lives!
Sorry SkiMangoJazz,
He's got a long way to go before I grant him TCS status. Pretty funny though.

......and HS is likely laughing his arse off....

I think he's scammed us all!! He is the most complex troll we have seen yet.

TCS was a pretender compared to HS.

Love it!! this is great stuff!! Brilliant stuff actually....

You da man HS!
Really was meant just as a joke, and I actually changed the wording a little to soften the message.

But it would be great if people stopped taking the bait, and let this insanity die.

HS will not take any advice other than that he should try out for the WC or the US freeskiing open. JONG!
EXCELLENT!

There are many remarkable similarities between Taichiskiing and H.S.... But the most striking and erie similarity is the following:

Remember the move that TCS called "Wild horse parts its mane?"

H.S. has a very similar move: "Nutty jackass shoots his mouth."

Way to donkey punch the fun out of this thread.

Highway Starlet, even I.......a lowly intermediate with no real skiing skill or style.....can see what you're doing wrong, it's just that obvious.

You are the best at one thing, however, and that's being the best Troll in a long time. Thanks for the fun!:

### Ma

This is my lst and last entry on this MA.

It only took 280 posts to call the type of fishing done, not flyfishing, not spin fishing, not bait casting but TROLLLLLLLLLLLLing

In a nutshell!
And yes, after reading the entire thread yesterday, it had TROLL flashing all over it. No one is quite this silly.
Top thread though, funny as hell.

I wonder where he got the footage from though? Did he plan this out last winter and ham up some runs, or did he pinch them from somewhere else?
Here ya go!
Actually guys/girls the scariest part about this whole thread is that Highway Star is not a troll. If he was we could have banned him along time ago. He actually BELIEVES the stuff he is saying... which actually makes it just that much worse. : : It has been fun so far. The MA that I gave him didn't even require a lot of thinking because the flaws were so obvious, so it has really been a fun thread to participate in because it is based on some of the simplest concepts of high level skiing. For those willing to read through this mess, there is really a lot of good technical information in here (if you DON'T read Highway Star's posts).

You are absolutely correct! He is not a TROLL, he is a delusional egotist and lousy skier!
The best part, I must say, is that it actually turned out to be a good MA thread, once you sifted through all the chaff.

But at some point we all gotta say, "The money's on the dresser baby. I'm through wit' you."
