Composite bows and the art of no paradox.
I am probably going to start a firestorm with this but it's good information for those that like the composite bows and eastern style bows. Before I begin please realize that in the english speaking...

It most certainly does prove that paradox still occurs, and to a marked degree. The shove of the bowstring against the stationary arrow has to cause the arrow to buckle under pressure. Has to.

I totally agree on that part, because its just physics.

Therefore you tense your back muscle before releasing. The muscle stretches the tendon connecting the arm to the muscle. upon release the muscle rests in this position and the tendon moves the arm....

well, but thats whats visible in the video, isnt it? previously established back tension pulling at the bow arm. and the arms mass & inertia delay all motion until the arrow is long gone. thats...

In video 1 he moves the arm in the (from my point of understanding) correct way to the side. Problem is, this happened after the arrow has been released, slammed into the handle and left the bow...

Thanks for comments! This is very interesting subject. Shooting style can affect to results. Alex (who is shooting) confirmed that when he is shooting rigid bow hand, arrows are flying badly and not...

it seems to be impossible to avoid the arrow hitting the grip where it gets deflected and starts to wobble in flight (tested and failed with arrows from 35-105# spine with a ~60pounds bow.).How long...

BobAll my arrows are between 32 and 33 inches long. I can't shoot shorter ones without an overdraw-device. When it comes to later Turkish bows, they had a lot shorter arrows, but an Ottoman Turk from...

Simon- Sure, I will try to explain better, and even back up a little bit. I suspect that a longer arrow may act differently for more reasons than extra weight. Watching the videos shows arrows flexing...

Bob, thank you for the extra explanation. I think upon release the arrow is in the same stage as a guitar string while you are striking - or better: bending - it with a pick. In this stage you can't...

There is definitely considerable possible variations in the flexing of the arrow and which part potentially strikes the bow based on that. That depends on the length of the arrow and the dynamic spine...

Simon Thanks for your response to my theories about harmonics. I may try to make a better explanation of the physics when I can apply better it to a specific circumstance. Some thoughts I had seem to...

You can still have arrows buckle either way with thumb or fingers. Those videos just happen to show one way for each style of shooting. Buckling around the bow initially seems to intuitively make...

Pat just to be clear in what you are saying here.... "We are always told that all bow woods are actually just as "fast" when bent but this clearly isn't the case when it comes to arrows." I read this...

Pat as for which direction the arrow bends, I think that there are three major forces acting on an arrow at release. I will list the two more predictable ones first. 1. deflection of the nock end by...

Tuomo-would you tell us a little more about the time line you posted? is it for the arrows in the videos?8 ms arrow’s maximum bend and arrow has moved about 35 cmis this bend away from the handle as...

Rsmith - Yes, the time line I presented is in realtion to the arrow. The maximum bed is away from the handle. That 3 ms, when arrow is not touching riser, is the the moment when the arrow is not...
