If somebody here knows why just tell us...
To answer your question, Magnifico, a few items from our archives here at EpicSki (there have been many discussions!):
What is best edge angle for max grip? (Link is to my post #17, but the whole thread is worth a read)
Relationship of carved turn radius and ski sidecut radius (Link to thread discussing your question, Magnifico, and includes several links to other relevant threads)
Sidecut vs. Turn Radius (Link to an early post by Tom/PhysicsMan, defining the formula for calculating carved turn radius from sidecut radius and edge angle)
That should do you, for a while.
So, Spooky, you really do not understand the concept of "frames of reference," then, do you? You seem to insist that motion is somehow absolute, and that therefore, there is only one way to look at it. But just about the only absolute about motion is that it is not absolute--it is relative to other things, relative to the frame of reference ("coordinate system," if you prefer) that you choose to observe it and describe it from. If you want to continue the discussion, at least with me, you're going to have to demonstrate that you do, in fact, have a grasp of that concept. Otherwise, it is nearly pointless to discuss a concept that is so heavily dependent upon that understanding.
However, I will ask you some simple questions: when you swing a weight tied to a string around in a circle, what is the string doing to your hand, as a result of that motion? (Yes, we all know that it is applying a centripetal--not centrifugal--force to the weight on the other end--but what is it doing to your hand?) If you want to suggest that there is no "real" pull (no actual force) acting on your hand--that it's just some imaginary thing, some "feeling," some "fictitious," but not real, force, well, I'll be interested in your justification of that premise. But if you agree that the pull on your hand is real, and measurable (which of course, it is, and I believe that your admission that "it [the 'fleeing from center'--your words] most definitely is real" suggests that you agree), then it must have some sort of a cause. And what is the only thing that can cause "fleeing" (acceleration)? According to your oft-referenced Newton, the answer is "force." And what is the name of that force?
Yes, I'm sure you'll insist, and you will be correct, that the force pulling on your hand is "merely" the result of the inertia and acceleration of the weight on the other end of the string. That is true--in fact, it is essentially the definition of "inertial forces," of which centrifugal force is an example. But it does not change the fact that the force pulling out, away from the center, on your hand is as real as any other force.
For you, and anyone else interested in more discussion of Centrifugal and Centripetal Forces, I will refer you to one of the better EpicSki discussions of the topics, this one initiated by Tom/PM or "PhysicsMan," and itself referring to several pertinent and prior discussions:
Some comments on centrifugal and centripetal forces
"There is no "stationary aether" either, but then again there is only theory, or is there?" Good question, Ghost! Do you know the difference between theory and reality? In theory, there is no difference between theory and reality, but in reality, well, sometimes there is.
And you thought we never got around to discussing physics, jesinstr! Welcome, again, to EpicSki!
