The "Slow Line" (detailed discussion)

In the thread, The "new" short turn or ohhhh my legs hurt !!! that Oz started, Milesb and I got into a side discussion (sorry, Oz!), so I decided to start a separate thread so as not to derail his any further.

Our discussion started talking about the G forces you generate in a "fast line" and a "slow line". From there, the discussion moved to what exactly does a typical slow line look like (ie, more traversing, turning back up the hill a bit, etc.), etc.

Some of these issues have been discussed before but some haven't. For example, Milesb suggested that if you turn up the hill a bit, this will make your next turn of longer radius, so it will take longer to get to the fall line (if you continue to carve), you will pick up more speed, and so you won't actually have gained much by turning back up the hill a bit. (Milesb - I hope I'm paraphrasing you correctly). He also posted a nice hand drawing of this type of turn.

I'd love to see more discussion of this, maybe get some input from BobB about the shape Milesb drew, etc. Obviously, the focus is pure carved turns while freeskiing (ie, no gates to define the shape) on a mildly steep (or above) wide slope on fast snow.

that looks like some Warren Witheral talk and drawings.
Tom, I guess we make a good team. We have managed to make EVERYONE's eyes glaze over!
For example, Milesb suggested that if you turn up the hill a bit, this will make your next turn of longer radius, so it will take longer to get to the fall line (if you continue to carve), you will pick up more speed, and so you won't actually have gained much by turning back up the hill a bit.

Not really true. When you turn uphill you also slow down considerably so although you take longer for the next turn, you also start from a slower speed. And if skiers would learn how to turn uphill to slow down you would see far less skidding.
The way I see it, you have two forces at your service, gravity and friction. If you use gravity you don't need so much friction...
Actually, the discussion was really about g-forces in turns. My premise was that a slower line subjects the skier to higher g's than a fast line. And if you take a REALLY slow line (as in the picture), to maintain a somewhat constant downhill speed, the start of the turn will be very big, because the skis are going too slow to generate enough force for a tighter carved turn. Indeed, go uphill enough, and it will be almost impossible to start a new carved turn. Then, in tightening the turn at the end, you will experience VERY high g's. You very seldom see anyone skiing a line like this, but it is alot of fun.
Now in general practice, what happens is the skier pivots the skis into the fall line. But that's not what we were talking about.

Amen!!! Say it again AMEN!!! [img]smile.gif[/img]

One of my favorite ways to explain this to students is simply to say "gravity is our friend, it can speed up us (turn downhill) or it can slow us down (turn uphill)". When students get that concept great things can follow.

We now return to the 55 lbs of educational material I just received from the PGA for my level 1 checkpoint. Oh my Gawd, what is all this stuff? :
