There is NO paradox from a centre shot (or near centreshot) bow, as the arrow lines up with the target all the way from full draw to brace height if it is let down slowly. With an English Longbow, as the sting is slowly let down the arrow points further and further left until at brace height it is pointing a good bit left. The paradox is that, one would suppose the arrow must pass through it's start point (brace height) when loosed and thus should fly hard left. It doesn't! That is the paradoxical behaviour! The ANSWER to the paradox is that, it flies straight to the target because the arrow flexes. The flexing of the arrow is NOT the paradox... it is the answer to the paradox. The wikipedia article explains it.

Best demo ever. Every archer is aware of spline, but few have never seen these results. Thanks.

You would be surprised how many "Archer's" DO NOT know about the Paradox. It is not well known to Newbies in archery and really should be a WARNING on all arrows purchased.

It never ceases to amaze me just HOW much Arrows flex, at the Bow and at the Target, you'd swear they were made of rubber after seeing this video! Thanks for posting, it's the best one I've seen on this topic.

The earlier paradox video of yours was already a great and now this new is just making these two to be perfect material to every archery to understand the paradox. Thanks for sharing! I wish you all the best my friend.

Fascinating to see so much flexation of the arrow shaft. I had no idea. Didn't care for the music. Thanks for posting this.

This was an informative and very well put together video. Always looking at archery videos, I'm surprised I didn't come across it sooner. I appreciate you taking the time to do make it. Thanks for sharing it.

Great teaching tool. Thanks for taking the time and the risk to shoot this. I will be showing this to my students.

One of my all-time favorite videos!

Beautiful work, thank you for this piece of art and knowledge. Sometimes you have to break things so others understand how things work and why those things work the way they do. It's amazing how much can be communicated when an arrow wraps around a bow riser and splinters.

wow that arrow @ 6:05 blew my mind. I imagined a wooden arrow and the amount of flex... I thought of what we think as solid wood acting somewhat like a fluid. Really amazing footage. Demonstrates how our perception can be totally flawed. Very nice imagery. Thanks for putting your time into this.

Keep in mind that the distortion was greatly amplified by high-speed digital photography in the same manner as the vibration of a guitar string or the edge of a car door is greatly amplified and distorted by high-speed digital photography, which very seldom gives you a truly accurate representation of what's going on... unless you go all the way up to EXTREMELY high speed. Any time your frame rate and the arrow's / bowstring's resonance are anything like coincident, you'll see wild unrealistic distortion.

@@yugen Trying to prove? Why might I be trying to prove anything? It can't possibly have been an "extremely high speed camera". Extremely high-speed cameras provide stop motion on objects traveling several times the speed of sound. These arrows almost certainly don't reach speeds over about one-eighth the speed of sound. The distortion I'm talking about is calle "aliasing", and it's demonstrated here: kzread.info/dash/bejne/ao17s8-PY7Hefaw.html Here's a more realistic digital capture of guitar strings (bass, in this case) with very little aliasing: kzread.info/dash/bejne/kY561a-NZ9yzhNo.html I'm sure you're familiar with the visual effect of aliasing: kzread.info/dash/bejne/dK2I1auMdru7n7w.html I tried to find one of the slow-mo car-door videos with the stereo blasting, showing severe aliasing distortion, but I couldn't. Sorry. At any rate, that's what I'm talking about here. The arrows do experience some flex, there's no doubt about that. Nearly 100% of that flex, though, is one standing wave as long as the arrow; it isn't a bunch of little waves along the length of the arrow. The little waves we see are examples of aliasing due to conflicts between the camera's frame rate and the arrow's self-resonance.

Great footage .

They are called Flu-Flu fletchings. They create more drag as they fly and are traditionally used to hunt birds/aerial targets. I know I've seen them for sale on e-bay before made by custom fletchers. However, if you are into making your own, it's quite a fun hobby once you get into it and really doesn't require a lot of tools to get started.

From Wikipedia, the free encyclopedia Jump to navigationJump to search Not to be confused with Zeno's arrow paradox. Arrow direction when braced and when at full draw. A = bow riser/grip, B = median plane of the bow, C = arrow aiming line and trajectory Arrow flexing both towards and away from the bow handle. The archer's paradox is the phenomenon of an arrow traveling in the direction it is pointed at full draw, when it seems that the arrow would have to pass through the starting position it was in before being drawn, where it was pointed to the side of the target. The bending of the arrow when released is the explanation for why the paradox occurs and should not be confused with the paradox itself. Flexing of the arrow when shot from a modern 'centre shot' bow is still present and is caused by a variety of factors, mainly the way the string is deflected from the fingers as the arrow is released. The term was first used by E.J. Rendtroff in 1913,[1] but detailed descriptions of the phenomenon appear in archery literature as early as Horace A. Ford's 1859 text "Archery: Its Theory and Practice". As understanding was gained about the arrow flexing around and out of the way of the bow as it is shot (as first filmed by Clarence Hickman)[2][3] and then experiencing oscillating back-and-forth bending as it travels toward the target,[4] this dynamic flexing has incorrectly become a common usage of the term, causing misunderstanding by those only familiar with modern target bows, which often have risers with an eccentrically cutout "arrow window" and being "centre shot" do not actually show any paradoxical behaviour as the arrow is always pointing visually along its line of flight

i get it that this is simple physics, but it's more of a beautiful dance with the twist and sway of the arrow. nice camera work, good shooting.

Amazing to see the arrow flex as much as it does. I also notice that with properly spined arrows the actual arrowhead does not diverge off course nearly as much as the rest of the arrow...As a non-Archer, I'm assuming the that the objective would be to keep the arrowhead itself on course as regardless of what the rest of the arrow is doing...My guess would be that a completely un-bendable arrow would tend to veer drastically to the left in the case of a right-handed shooter. Correct????

Thanks!

Gentlemen, the arrows are of orthodox spin,i think it's false i think there are arrows made of PVC too.

amazing video buuuutttttttttt, how are your arrow spine measured? Seems backwards to me. 500 spine deflects .5 inches on the spine scale, a 350 spine deflects .35 of an inch, soooooo the lower the number the stiffer the spine, but in your video your numbers go down while the spines get weaker. What are you measuring. I shoot 31 inch 500 spine arrows out of a 40 lb recurve and they are too weak, looking to try 450 or 400 spine.

The arrow burst made me grimace....always wear bow arm protection...

Yes, that is correct.

Oh, those are flu-flu arrows too? I actually have a set with big feathers, and I've seen the spiral type. I just haven't seen that particular type with 3 fletchings that are shaggy. They are really neat looking. I actually bought my flu-flu set from ebay, but have never ran across the style you got. I'll have to look again. If you ever run across it again, may I ask a favor that you send me the name of the seller? Thanks. Lookin' forward to more of your archery videos. Take care.

Wt do you mean spine 25-30? Spine is from 1000 to 150 🤔 (more flexible - stiff) here at least

What are those numbers you're using to indicate the spine? I thought spine was expressed as 3-digit fractions of an inch and that lower numbers corresponded to stiffer arrows, but for you it's 2 digits and lower numbers correspond to more flexible arrows.

Wood arrows have to be spine tested and hand sorted due to the natural variations in the material and the labeling system essentially means that for a standardized arrow length and a standardized draw length, this particular arrow is properly spined for bows with a draw weight between, for example, 45 and 50 pounds. For aluminum arrows, the labeling system reflects the diameter of the shaft and the wall thickness. The system you are describing is for carbon arrows, but note that not every manufacturer has adopted the lower numbers equating to stiffer shafts. For example, an Easton 300 will be a 0.300 deflection shaft and an Easton 400 will be a 0.400 deflection shaft, however, a Carbon Express 250 will be a 0.400 deflection shaft and a Carbon Express 450 will be a .300 deflection shaft.

For wooden arrow spine you take the distance in inches between the rests for the arrow (eg. commonly 26 for a 28" arrow) and divide it by the deflection (again in inches) under a 2# load placed on the center of the arrow, A 0,4# deflection gives a spine of 26/0,4=65 From time to time you see wood arrow spine numbers followed by a # but that's erroneous since the value has no unit (as it is inches/inches). There are some charts to roughly determine the suitable spine but they can only tell you so much as it also depends on string height, the degree of deflection of the arrow and your technique.

If your arrowhead can penetrate that leather shield you used on your bow hand... then a broken arrow can also penetrate it and ruin your bow hand. NEVER intentionally release an arrow that you think might break in your bow.

What I think of this is that cock or index feather are not important, as long as you use feathers it doesn't make a difference right?

+Brett Starr in this video of the explaination of Archers Paradox. Just because we have realigned are arrows to a closer to center of target at full draw does not mean the arrow is out of the paradox. The arrow is still wanting to going elsewhere than the aiming point. Plungers, modern rest, and cut away risers are helping to redirecting the paradoxed arrow to the intended target. The true paradox is how we interact with our fellow archers.

Beside the arrow being "Too Soft" as it were, Archers Paradox is caused by the three finger release! In Asian archery, ie the thumb draw from the right side, does not cause this problem, therefore spine is not concidered only weight of the arrow. Before you bad mouth me, please study this mans release. The string is always moving to the left on the release and then moving back to the right as the arrow leaves the string!! using the thumb release, only a very small fraction of the string ever touches the thumb ring and the string is NOT torqued or twisted in any way!

That's a longbow; not a recurve

Any chance you could rename this so that it doesn't mention "Archer's Paradox"? It's bad enough that archers don't know what you're showing is arrows bending, much less non archers. Wikipedia finally makes the distinction and we really need to stop the ignorance.

Most see video if you're an archer!

I'd rather have a wood shaft break on me then a carbon cus of that carbon shaft gets jabbed into your hand it will be a lot more pain the the wood

guess this is why i shoot a compound :)

Excellent photography showing the effect of the force of the string at release on various spined arrows. The reaction of the arrows, of course, is to flex or bend. Unfortunately, the title of your video implies that the flexing is the paradox. It's not. The arrow flexing is a response to archer's paradox. A paradox is a seemingly unexplainable observation contrary to common sense or observable fact. The term archer's paradox was coined back in the late 30s, early 40s when most bows were laminated or self bows of wood, that either didn't have arrow shelves cut into the riser or the shelves were very shallow. Thus, when an arrow was placed on the bow, it pointed way off line. And yet, when shot, it flew true to the target. That was the archer's paradox. How could it fly true to the target when it was pointing off target, and yet observation proved it to be true. We've since learned, of course, that the reason it can/does, is because the arrow (if properly spined) bends around the riser when shot. So, the flexing of the arrow is the explanation of what the arrow does in response to archer''s paradox, it is not the paradox itself. In modern compounds and some traditional bows in which the riser is cut past center, the nocked arrow can be made to align perfectly with the center of the bow, pointing directly at the target. There is no archer's paradox, and yet the arrow does flex when shot.
