It is really a fine piece of works, an art in itself. In its simplicity, PSIMAN illustrated/demonstrated all of the fundamental principles of parallel turns, as well as why and how carving turn works.

Really, how does it work?

LOL :face (334): :face (334): :face (334):

That toy skis better than me. (I am serious!)

Here's the comment I've posted for that video:

No muscles, no knee joint movements, so there are no up-and-down-unweighting, no foot shuffling for balance stance, or/and any other fine-tune balancing acts, in its simplicity, PSIMAN illustrates perfectly the principles and mechanism of the modern carving technique—"Tipping." Keep up the good work, it is a state of art, Bob.

P.S. For other readers, what is the principles? It is driving with your weight/center of gravity, in PSIA term, "GO."


Yup, it is well-made.

I believe this video is showing the hip joint movement but not suggesting ski without knee joint and ankle joint flex.

Look at this PSIA video demonstrator has a lot of knee and ankle flex. It's a suprise if any one ski like the robot with stiff knee & ankle. :face (50): :face (50):

The initial force of the turn is gravity/地心吸引力 + "centripedal force"/向心力, as centripetal force generates an opposite force "centrifugal force"/離心力, which slows down the pin movement and slows down the turn; when "centripedal force"/向心力 and "centrifugal force"/離心力 equal to each other, the gravity takes over, PSIMAN moves downward again, so the process of skiing continues until the initial energy is exhausted by frictions. It "illustrates" the "pricinples" and the "mechanism" of the modern carving turn, mainly, angulation and edging, "Tipping." The flex of PSIMAN's knees is actually showing the best skiing knee postions for we human.

Of course, human has muscles and bones, we don't ski like a robot; nevertheless, the reasons and ways we make a lot knee and ankle flex/movements, as well as various muscle tensions, is to maintain the "turning pressure" that demonstrated by PSIMAN. The PSIA demonstrator shows only a refinements.

So, are you decided to come back to the human realm?

Good for you, at least you understand what is good sking now. :face (330): :face (330):
