When that happens the car becomes very difficult to move forward as the wheels are fighting each other.
To me this suggests that if both skis are carving and the outside one is on a tighter radius, there is some scrubbing of speed going on. On the other hand, if the inside one is only lightly weighted and being "steered"(twisted in the direction of the turn) much less scrubbing is occuring.
Just some thoughts I was having as I read the above.
Man, you've got me thinking about this. Let's explore this further. So let's take the picture of me (hear he goes again), I would say that I am biased to the left ski but the outside ski is more loaded. Rick's Force Vector thing applies to those British cars the push into the corner, they simply aren't set up right past a certain turn - correct?
If one waist steers properly (don't worry, due to a PM from JASP I AM about to launch into another Tome) the inside ski can spend more time in the fall line then be there to top of the turn (so to speak). Centriptal force, with proper stacking, load that outside ski without the racer having to "try" and do it.
If you over steer the oustide ski to keep up with a pure carving inside ski, I totally agree with Slatz's analogy. The trick is to keep turning the trunk, I refer you back to the diagram, to move the outside ski forward in its little slice or cut relative to the inside ski (AOS).
And this is where I have to GO OFF and start a new post on the folly of me trying to explain "Waist Skills" in a one dimensional environment. Yes, I am quite insane.
After, what business does a 51 year old, C.E.O. of 2 companies, that is a total stuck truck, have any business racing? None! Or trying to teach racing, well there just might be my forte.
Slatiz got 1 MMB for this, nah, make it two (2)
, very thought provoking!
I move on,,,,,,,,
|The radius of the carved arc of the outside ski is smaller than the arc that the inside ski can carve given the observations from the photo, but the radius of the path followed by the inside ski is smaller than the radius of the path of he outside ski. It seem that therefore the inside ski must be guided in some way to keep it on the path you want it to follow. How is this being done? - Ydnar
Damn you guys are good, no kidding! 2 MMB's! Keep your own counts, very important, I'm deciding on what is going to be given away to 1, 2, and 3 place and all of it will be of value (yes, from my sponsors, as the eagles would say - Get Over it!).
Just biasing and loading the ski. How we do that iw 1) Waist Skills 2) proper alignment and posture (CoM, CoG vs. Centripital) 3) rolling the inside knee towards the hill (AH, here, he finally said it, we've been all around it but nobody has asked, hey what happens if you roll that inside knee towards the turn??). Well cranking that inside knee towards the center of the circle does what? It starts matching the edge angle of that accelerating outside ski (think about the golf swing, club head to hands). If both skis are carving by the end of the turn think of how much energy is stored, then you just need to know how to release it - forward and away, not up at you.
I've got to run, when I come back I am going to try to reconstruct this huge reply I blew up going back to JASP
: I want to address "Waist Skills". Why, because I just came from Tai Chi and as usual realized how awful my waist skills are compared to a 1 year student, how absolutely pathetic compared to Tommy, and then those dudes who have been doing it for 40 years. They ARE unreal. If I could only get a class of these cats to put on some shaped boards and modern boots what racers I could make. The would crush the Men's 10's in no time, I assure you!
If anybody wants to refer their Tai Chi master to me, I'm teaching 'em ski racing for free - and you too!
