Re: The practical side of considering loops as waves: Teaching and Self Improvement

I was quite happy discussing this in the physics forum in a thread about this very thing, until you started another thread specifically excluding discussion of waves in loop propagation. And you can still post there, I see no issues at all. Why not open a new thread about waves. I've started the ne...

Re: The practical side of considering loops as waves: Teaching and Self Improvement

Hi Paul, regarding #162, thumbs up, very nicely written. Graeme, But please remember that physics was never meant to be discussed in this thread. It's about teaching, remember? Of course, this is all too hard to calculate (as Torsten admitted earlier) so just forget I ever tried to help people under...

Re: The practical side of considering loops as waves: Teaching and Self Improvement

Graeme, a) medium What does that mean? It's a single word without context. Any mechanical waves requires a "medium of transmission". For a string wave it's the string mounted between two pegs. But what's the medium if we assume the loop is a wave? If the fly line is the medium, we would accelerate m...

Re: The practical side of considering loops as waves: Teaching and Self Improvement

Paul, I had the same picture in mind (#111), nice drawing. Graeme, even without gravity the loop would propagate. I see some major issues why the transverse wave concept fails to explain loops: (a) medium, (b) mechanical waves don't transfer matter (but energy, movement of mass is limited), (c) prop...

Re: The practical side of considering loops as waves: Teaching and Self Improvement

Graeme, from the other thread, Mends must be a constant source of frustration for you. The idea of a mend is to transport the line away from where it would otherwise land. Place a wave in the line and transport it sideways. Not really frustration because I'm looking at these topics pretty much emoti...

Re: The practical side of considering loops as waves: Teaching and Self Improvement

Graeme: Interesting answer. What is the force causing the change of momentum at the loop front? If there is a speed difference between fly and rod leg there exists a force too, because the slower moving bottom leg pulls at the front of the fly leg (and vice versa, Newton's third law) => tension, bec...

Re: Analysing loop propagation 2

I'd like to discuss it here, but you know, "bollocks" .... :???: The moderator has decided that discussions about things he doesn't agree with need to be isolated. He doesn't agree with my explanation so I'll keep it to myself. Don't be offended, I'm sure I'm talking sometimes a lot of bollocks. I ...

Re: Analysing loop propagation 2

How about you, Torsten? How do you decide which approach is best to analyse loop phenomena? I'd do a "market research" first, collect papers, principles etc. What we like to do then in our company for example is then to construct a decision matrix - this can be helpful for a better, more objective ...
