Violadamore Posted December 9, 2023 Report Posted December 9, 2023 12 hours ago, David Burgess said: No, the result is not the same. Near the surface of the earth, the main directional force of gravity is always toward the center of the earth. Suckage can apply a force in any direction. I am absolutely astonished that anyone with even the slightest bit of intelligence could have failed to figure out yet that violins are primarily suckodirectional. And so the Theory of General Irrelevancy joins ND, GR, MOND, and the rest of them, giving us the priceless concept of suckodirectionality. You oughta get a Nobel for that alone. 12 hours ago, martin swan said: ..reguz wants to...........just troll people who don't give a shit...........

Dennis J Posted December 9, 2023 Report Posted December 9, 2023 I don't have a problem with Reguz's string load deformation explanations. However I'm puzzled by the theory surrounding STLs. They exist on plates I have made but they appear as a consequence of the method I use to complete the arching based on templates I use. But I suspect they probably exist on well arched violins anyway. I only know of one way to plan and execute a specific arching shape using predetermined heights and inflection points for the long and cross-arch profiles.
reguz Posted December 9, 2023 Report Posted December 9, 2023 PETER. Det är uppenbart att ingen förstår vad som försöker förklaras. Frågan är var sker formändring. I mitten av instrumentet (stall/ljudpinne) som visas på så många av Stoppanis animationer eller förhåller dt sig på annat sätt. Man måste börja tänka. Det är avgörande för att förstå vad som sker och hur man måste graduera för de krafter som angriper konstruktionen. Du har uppenbarligen inte heller förstått. PETER. It is obvious that no one understands what is being tried to be explained. The question is where the shape change takes place. In the middle of the instrument (stall/sound stick) that appears in so many of Stoppani's animations or otherwise. You have to start thinking. It is crucial to understand what is happening and how to graduate the forces acting on the structure. You obviously didn't understand either.
reguz Posted December 9, 2023 Report Posted December 9, 2023 Dear Denis. Is it really you undestand what string load produces. Some people: Stoppani, Gough, Woodhouse, Goli/Carlsson and lattely Curtin all say the center move up/down in the dynamic state. In the static state the center becomes moved downward. It it this you also understand and say is correct? You only need to give a simple answer on that question

Why is it you do not read my site ww.zuger.se there you can read all about the complete arching shape. So it is not just the cross arc shape under the bridge feet. What is it you can contribute with Hugo? So I have been to your website, and knowhere does it address what the problem is. So what exactly is the problem that you say you have the fix for? I am expecting a simple straightforward answer that the layman can understand. What is the problem?
martin swan Posted December 9, 2023 Report Posted December 9, 2023 Problem is that reguz is addicted to conflict.

It it this you also understand and say is correct? You only need to give a simple answer on that question In the static state, under string load, the upper and lower bouts will rise in relation to the centre bout or put another way the centre bout will move down in relation to the upper and lower bout. That seems obvious to me. If dynamic state means while being bowed up/down sounds probable to me, but I really don't know much about that sort of thing.

reguz Posted December 9, 2023 Report Posted December 9, 2023 No, I am not at all conducted to conflict. But by all of you not answering on any of my questions that is not very polite and that makes me writing straight fore ward in the hope getting some answer. So, by you being polite there should come an answer on the question. Is it it your opinion that the center of the instrument become forced down ward by string load you at least make open what you believe. This is a straight fore ward question that may give a simple answer Yes or No. So please answer me. For Denis, I talk about the condition as we see Stoppani and other shows. The instrument supported on the end blocks. What happens when string load start acting? Give their doing right result as they show with animations in the static condition and with video Mode conditions for different frequency? That it is about Straight fore ward questions not in addiction to conflict.

Deals with the ways that generally long-ish thin-ish shaped things like tubes, columns and plates buckle under axial loads. Within the complexities of having a soundpost and offset loading by the strings which adds a couple ( ie a torque) to the axial load, the description of of old tops given by Martin Swan fits within the situations described by Timoshenko very well. Wave-like buckling. Pre-dates fem/fea. I have a copy.

reguz Posted December 9, 2023 Report Posted December 9, 2023 Which structure is moving structure caused by string load and alternation string load thus the dynamic condition. This is thus two quaestions related to each other
reguz Posted December 9, 2023 Report Posted December 9, 2023 Yes David, I would be a poor fellow as long as I do not get an answer ithe question above

This is thus two quaestions related to each other This depends entirely on what point(s) on the violin one is using as the static frame of reference. You keep insisting that there is only one which is correct, which is, of course, incorrect. Example: When I am standing motionless relative to the surface of the earth, how fast am I really moving? (Hint, there are numerous correct answers, depending on what my speed is being measured against)

The question should start with how the violin is supported.

I see. So the sun revolves around the earth, and around me? And our galaxy revolves around the planet earth?

And our galaxy revolves around the planet earth? Seems right except maybe 15,000kM too far East and a bit North. Also the faint echoes of the big bang and the signals from the early universe rotate about the same point.

And our galaxy revolves around the planet earth? Something like that. If one thinks that one is the center of everything, one becomes static. And think about it. It's even hard to imagen that the earth is wobbling around you, even more difficult to imagen that this sets the sun in motion and also the entire universe. Not meaning I think you think you are the center of the universe! Imaginary thinking can be healthy or not.
