Stiffness and Tip speed

[bartdezwaan]

The discussion about fly rod stiffness and casting distance is interesting.
Till shortly I took it for granted that stiffer rods cast further.
As with most things, nothing is what is seems.

Is it possible to theoretical analyze if rod stiffness determines the max tip speed that can be achieved?
I might have chosen the wrong parameters, so change them if needed

I think you should go back to a soft rod, Bart.

I think you should go back to a soft rod, Bart.

You wish!

[Paul Arden]

I’ll swap the HT10 for an HT6. No charge.

[bartdezwaan]

No way! This rod will become a collectors item.
It is the rod the legendary King Bart set the BFCC record with in 2018 (and a lot more to follow).
It’s No. 2 in the range. Only some crazy polish guy owned one before him.

I believe that the speed of light is the limiting factor for tip speed but I'd ask a physicist about quantum effects if I wanted to be certain

[bartdezwaan]

Vince. You’re up for taking a serious attempt at this?
I am sure you can.
The speed of light also is the limiting factor for the speed of a car. That does not mean we can’t reason about how fast it will be given the engine, shape, etc. I am not saying the two examples are similar BTW.

With or without a haul Bart?

I think we should leave to haul out for now.
And maybe treat arm and wrist rotation speed as constants.

The important parameter is loaded speed, which depends of stiffness, of an inertial rod parameter (equivalent mass at tip) and of the mass of the carry.

I can compare a 906/908/910 set of rods, with or without haul. I understand that you want a given casting stroke (e.g. 170).

Would that fit your request?
