Here is one more experiment. Upper picture has the binding with springs (this could be again substituted with NNN BC with flexor, Xplore with flexor, 3-pin with bending duckbill (the duckbill is a torsional spring)). Lower picture is exactly the same situation with horizontal force (hand) pushing t...

Seems like a dodge to me… Let me flesh that out… I have the sense that often, when something has been put to you directly on the forum, you tend to dodge directly answering the question. This makes it difficult to make progress in a discussion, which is evidenced by two of the longest posts in rece...

My education has included quite a lot of physics (Master of science in technology). How about you? The argument from authority is a logical fallacy. Not to say you don't know what you're talking about, but whether or not one holds X Y and Z degrees is irrelevant to a proposition's truth or falsehoo...

Thanks for the conversation, and patience all seem to still have some. I ski NNN-BC only, but think I now after reading understand what a cable would do. It lets a skier to lean forward against the spring without falling on one’s nose. Further, that lets you edge your rear ski more. So @GrimSurfer ...

If you would try to make the above experiment with a truly neutral binding, like a TTS pin binding with the cables detached, you would not be able to produce any tip pressure by pushing the boot, until the range of movement in the binding runs out.

You can make an experimental test about the tip pressure: take one ski (with a binding), one boot, two scales, and some Voile straps. First put the ski on the scales, and tension the binding springs with the Voile straps like on the bottom picture. You will see roughly 50/50 split of the weight on t...

First of all, thanks Stephen for trying to be constructive. I guess you are right that we are mostly debating pretty simple things here because we cannot explain those things properly. Then, to the fun part (the physics debate) ;) And here comes the same statement repeated 100 times Yes, as the same...
