Re: Line configuration affect on rod
Hi George Let’s try answering your questions When a given mass is moved by a given force by two levers of the same length but different stiffness isn’t the load the same??? I understand the “load” as the force generated which is the product of mass by acceleration applied to that mass by levers, but...

Re: Line configuration affect on rod
Hi all Comparisons are not so easy. Considering a given cast for a given mass of line and two graphite rods (905 type), one rod being faster than the other, then the casting model says that there is: • A larger tip speed for the faster rod at launch time • More elastic energy stored by the faster ro...

Re: Evaluating the Haul
Hi Walter The translation speed, like others, is the absolute speed (along the path). In this case the path is nearly horizontal: Paul 170 FC paths.JPG The important point is the timing of events: translation peak speed at 0.792 s rotation peak speed at 0.834 s haul peak speed at 0.871 s line hand p...

Re: Evaluating the Haul
There is something like a factor 2 by comparison with the record. Could you please plot speeds (rotation, translation and line hand).
Many thanks in advance

Re: Evaluating the Haul
Correct Walter. That is about 900 deg/s in a very short time, typical of a competition cast.

Re: glass vs graphite
Carbon fibers are somehow brittle, it is the commercialisation of nanoparticles in resins which improved their resistance to shock.

Re: Evaluating the Haul
Hi Walter
FWIW here are the speed profiles for a 170 forward cast from Paul. Maybe you could take inspiration from these data to define your scenarios: Merlin

Re: glass vs graphite
I think we are reinventing the wheel, this topic has likely been discussed many times. Rod design is obviously depending on material characteristics (I disagree with Lasse on this point, if we are speaking of the same thing). Scott have been making (small) glass rods for years, I own two of them, bu...
