No worries James. And no need to apologize either. It is a good discussion, and that is the most important. [img]graemlins/thumbsup.gif[/img]

I was merely trying to contribute a few original thoughts on the physics.
|I agree angulation plays a role in maximising grip. However this is where the physics creates a dilemma. I contend that for carving a given line at a given speed the angulation is fixed by the edge angles and balancing forces required. Changing the degree of angulation during a turn will either result in a fall or a change of turning radius (carved turns only). So the dillema is, how are we able to alter angulation to manipulate grip without changing the line and speed. I think the answer is that we can't.|
|In controlled carving, there is a definite sequence of events. First the skier chooses the shape of the arc he desires to create, one that will take him where he wants to go. He then chooses the edge angle that will produce that arc for him. That angle will vary, dependent on the shape of the ski and other less influential factors, but for any particular ski there is only one edge application that will produce a specific turn shape in a specific situation.|

Fastman, how could you get sucked into this.
You know, that pressuring the ski fore and aft as well as changing pressure between skis, all can change the edge angle, without changing the turn radius and vise versa. [/QB]
|A suggestion as to "how to get it": Try walking with a pronounced wiggle in the rear, as some slinky women do on movies from the 40's. The rear (hips) actually go from side to side suggestively. The leading man's eye's light up. Hopefully you know the sashaying I'm talking about. Models do it on the catwalk.|
