when the whip joins the pirouette

Donnerstag, Februar 7th, 2019

Since the publication of my “Experimental investigations on the fly rod deflection” a longer time has passed and meanwhile there have been some discussions (especially on the sexyloops.com forum) about the concept Franz- Josef and I have choosen to clarify the redistribution of angular momentum (we call it “redistribution effect”). The preface Franz- Josef wrote for my investigations expresses the concept how we both tried to clarify the physical relations well and we are still convinced that this concept enables much more people to follow the content than too theoretical approaches using differential equations. In section F1 as well as in annex 2 and 3 of my investigations Franz- Josef and I are mainly talking about the “pirouette” and the “whip” effect in order to explain the redistribution of angular momentum. This essay is going to look with fresh eyes on the interrelation between the “pirouette” and the “whip” effect and how both effects redistribute of angular momentum.

experimental investigations on the fly rod deflection

+++++++++++

update in november 2014 – the revision 2.0 is published ! The english translation is out now !

In the revision 2.0 I added some investigations – especially about the impact of the mass of both fly rods and about a casting movement that keep the tip of the rigid fly rod on a straight path. With pleasure I anticipate that all the criticism can’t question my investigations. The revision 2.0 is completing my investigations and all opened (“critical”) questions should be answered.

With this videos I try to explain the effect of the conservation of angular momentum in fly casting.

 

A more detailed physical explanation, why the flexible fly rod concentrates energy towards its tip, could be seen here:

During the past year 2013 I occupied myself with the deflection of the fly rod. With a commercial digital camera, which takes a video by 30 frames per second, a casting sequence of me was catched and I pointed the video out frame by frame. I compared the conclusions of my casting sequence with the conclusions an absolutely stiff rod reveals under the same conditions. This comparison shows that the flexible fly rod possesses a lot of advantages. For example one advantage is the efficiency, which is more than double times higher in comparison with the absolutely stiff fly rod ! It would be a pleasure to me, if my investigations could help to understand the fly cast better.

My special thanks go to the physicist Dr. Franz- Josef Schmitt for his accurate translation, preface and support.
