Re: Analysing loop propagation

The explanations nearly all require an understanding of how the speed of progression of a wave through string can be controlled using tension. The others focus on the mass density of the string and how it affects the transmission of that wave. You know, mechanical impedance and all that shit ... (It...

Re: Analysing loop propagation

Hi Graeme Interesting list, I would love to hear how treating the loop as a wave makes it easier to explain those things, as opposed how they are explained now :) Cheers Lasse Perhaps at another time in another sub forum. This section is mainly about physics (but I always like to relate that back t...

It’s complicated and I just think it takes us down a rabbit hole.
Can we just give the Flycasting Physics Sub-Forum this name please? :D

Re: Analysing loop propagation

I'm not implying anyone here is a flat earther, but I'm going to paraphrase this to show how a deeper understanding of underlying concepts can help in ways we do not begin to appreciate until the basics are established: We spend too much energy on useless topics. The earth is not a sphere then, so w...

Re: Analysing loop propagation

So you are unable to see that a loop is a transverse wave with a loose end in the medium? Okay, I thought that was pretty clear.

Oh well. I guess we won't analyse loops again. :D

Cheers,
Graeme

Re: Analysing loop propagation

And here we have the results of the thought experiment I mentioned earlier, now presented as a physical experiment: https://youtu.be/zHlFlChF1uo What you should observe here are a few quite obvious transverse waves that propagate upwards towards the tethered end of the line. If it wasn't tethered an...

The tip trajectory. You may include a circle if you wish. At some time it does not represent a mend anymore.

So which of the casts was the last transverse wave? And why?

If I throw my line against a wall, the wave stops, why does the rest of the line all end up against the wall anyway?
Because the fly leg is also a projectile. This thread is about loop propagation, but the two are closely tied.
