More: Acceleration/ tip velocity

Responding to statement 3 below. Like in my last response to Server's point, I agree that the maximum rate of acceleration is at the maximum load. but acceleration (increasing velocity) is continuing to RSP at which it would be 0. Force = mass * acceleration so once force is 0 when the rod is straight acceleration would have to be 0, but velocity is maximum. This would be true for a simple mechanical spring moving in a straight line. The final velocity is the mathematical integral of the total acceleration. So even if the rate of acceleration is decreasing (not the same a decelerating or negative acceleration), the velocity is still increasing, just not as fast. That is it is not accelerating as fast, but it is still accelerating up to RSP (in theory).

Anyway, I find it an interesting statement that from experiments "the maximum rod tip velocity is between the point of maximum rod load and the RSP, not at the RSP." I expect this is related in part to the fact that the rod is not as simple as a linear spring (which travels in just two dimensions), the tip is not traveling in a strictly straight line at the final stages during turnover (turnover arc). It also may be a factor the fact that there is a fly line attached, air friction, etc. I'd like to here others that have insight into this and I'd like to see more experimental data if anyone has some. I have found a different paper by Nolan and Bruce that plots tip velocity, and am going to look at it tonight.
