Connorchap Creations works with bullets too Start with a 22 short, slowly make your way from that to rifle rounds, then shotgun slugs, then 20mms, then an 88 just to tie it altogether
So at a very long range, you realy don't want to be hit by a longbow. Because a man Who could throw a bow that far would be a fearsome opponent. He truly is a Brit! haha
sometimes the tiniest moments of silly humor in these videos totally gets me. like when he pretended to throw the rock and you hear 'ow!' i just wasnt expecting it there and cracked up
It makes me snicker to hear Lindy always default the opponent as being a Frenchman. I know there's an historical reason for it, but it amuses me none the less.
If anyone's interested, the equations for at projectile in a vaccum are (y(t)=½*g*(t^2)+v_0*sin(θ)*t+s_0y, x(t)=v_0*cos(θ)*t+s_0x), this is ignoring wind resistance, then drag can be calculated with this equation: F=½*C*A*ρ*(v^2) F=force y(t)=displacement in y-direction at t x(t)=displacement in x-direction at t t=time g=acceleration due to gravity v_0=initial velocity θ=angle between x-axis and point of fire s_0y=initial displacement in y-direction s_0x=initial displacement in x-direction C=drag coefficient (different for every shape) A=largest cross sectional area in direction of motion ρ=density of the fluid the object is moving through v=velocity
@@freshrockpapa-e7799 Ah, so you've never been to a Middle school on a third world country, perhaps this might help, I'm about to finish university (I'm from Mexico) and this is the first time I have ever seen that equation.
I often find myself rewatching Lindybeige videos from a few years prior. I've already seen them and know the information. However, they are pleasant to watch and his jokes never lose their effect. Well done! Wishing I could "thumbs up" this again.
I think it's because many people imagine them being a solid metal rod. Maybe associating it with it's name, which makes them think of bolts in modern context as pieces of construction hardware :)
With MODERN archery they have a measurement called "Spine Weight" which refers to the strength of the arrows shaft. The purpose of having the correct spine weight, in relation to the poundage of your bow, is to help the arrow fly true'er through the air. When you fire an arrow, the force of the string bends the arrow, as Lindy described, and indeed if the Spine weight is too light, the arrow could break, BUT that is not the primary function of a correctly weighted arrow (shaft). Because of the force on the back end of the arrow, the arrow bends, and it will continue to bend back and forth throughout it's flight, this effect lessens as the arrow fly's. BUT, if the spine weight is to low, or to high for that matter, the arrow will not have straighten out before it hits its target, resulting in the arrow not hitting its target straight on, but rather hitting its target on an angle. resulting in less penetration. if the arrow is correctly "weighted" for the bow, the arrow should hit its targed straight on, achieving maximum penetration. SO in conclusion, the thickness of medieval arrows, was not just to prevent snapping the arrows, but rather to ensure a clean, direct and straight, hit on the target.
Have you seen SmarterEveryDay's (Destin's) video about this? That's how I learned about the archer's paradox. He meets a guy who can shoot an aspirin tablet clean out of the air. It's awesome.
I like how many of Lindy's videos are so spontaneous; it's obvious here, when you see his surprise, not expecting the rock to move when he blew against it.
Most underappreciated comic relief. Rewatching this video semi-regularly, and it just strikes me again and again how incredibly well rythmed and produced (yet simple) it is.
“Adjustable spanner” Huh, so “throw a spanner in the works” & “this throws a wrench in things” aren’t just figuratively the same they’re literally the same.
bossmanviking yes, because you said they aren’t the same but they’re literally the same phrase, just with a word translated from one version of English to another. Neither phrase is poetic, or if they are they’re equally poetic.
>Stone, Pebble Lindy we use those terms here in the states too. Granted, pebble just means "tiny rocks" and stone is used to refer to what something's made out of.
arrow thickness is for penetration not for withstanding the rather gentle force of a bowstring releasing. You can shoot a thin arrow at something easily but what does it do when it hits something hard, the shaft breaks off the head losing the majority of its energy. a thicker shaft is so when the arrow hits its target it doesn't break but instead transfers all its energy to the target.
+grazzitdvram But to launch heavy arrow to reasonable distances you need harder launch and this is where material resistance comes in. You cant really make millions of arrows from wood so people had to be creative.
+grazzitdvram Have you ever hit yourself in the arm with a bowstring? Apparently not, because otherwise you would know that it freaking hurts and that a bowstring isn't gentle. So they made the arrows thicker to be able to make the bows stronger, however thicker arrows certainly help to prevent them from breaking aswell. As a German I'd say they hit two flies with one flap, but I don't think that makes sence in English ^^
And all you idiots (except maybe gigaboost) still use miles. Hell, I think your miles are different, too. Now I just have to figure out how to turn that into a joke. And also, I don’t mean to offend anyone with my use of the word idiots. I swear like a sailor.
I only have 1 visible scar, and it was because i used a lighter arrow on a heavier bow. Be careful with bows, they're not toys. Arrows breaking when firing can go in any direction; in my case, through my hand
+Ethan Porter Relevant only in that they're both ranged weapons, but it always amuses me imagining the look on the first boomerang-user's expression and the panic overtaking him as the implement came back in his general direction.
+Braydon rantall He mentioned shooting a longbow at the French, he's definitely English (I know him personally too, that helps, and I'm French, that doesn't!!!!). ;)
Watching Lindybeige videos is like inviting a knowledgeable, eloquent, funny and just nice friend to tell you about military, history, warfare... This is how my brain prefers to take in information. I learn so much every time...I LOVE this channel! Thank you so very much!
You've left out one or two important stress factors! As the archer draws the bow, his fingers impart some twist on the string which effectively pre-loads the back or notch end of the arrow, at full draw, such that it wants to untwist against the firmly fitting notch which for a righhanded archer is in a counter clockwise direction. This has the effect of applying a torque to the arrow which lies partly on the hand of the archer and resting against the left side of the bow stave. The force increases the bend force along the stave as does the fact that the arrow isn't being released straight but at an angle equal to the tangent(-1) of half the bow stave thickness to the length of draw. The arrow upon release with the twist imparted and the moment of force due to inertia wants to bend itself around the bow stave upon release before straightening in flight. This doesn't occur as much in some centre or "through shot " bows that release the arrow in a straight line and release aids are used here to prevent the string twisting under the fingers which otherwise could throw the arrow off centre. Now if the arrow is TOO stiff then it bends less around the bow and for a right handed shooter will deflect over to the left. If it is not stiff enough then it will not fully stabilise in flight but "wobble" and initially tend to the right or even snap with the stresses. Arrows do in fact have to be graded by stiffness for this reason by both the draw weight of the bow and by the length of draw...simple physics can be used but in medievel times archers, fletchers and bowyers all knew what grade of arrow was needed. The barrelling thickness and length may also have been determined by the type of arrowhead being fitted. The heavier the head the greater the initial inertial moment at release, the greater the force alplied and the thiccker and stiffer the arrow stave needed to be. These days we use Port Orford Cedar for wooden staves. Back then ash was used with harder timber sometimes spliced in nearer the tip to improve strength and lessen the chances of the stave breaking near the tip upon impact especially with armour. The thought and knowledge and skill of these medievel fletchers and makers of arrow blanks was fabulous. That's right, I used the word " Fabulous" because I'm English!
Good video. I watched this channel ages ago (and promptly queued two dozen or so more of Lindy's video's), and now I find that it loses very little in da capo. He eloquently conveys ideas and concepts previously foreign to the great majority of us, and those are generally well-considered and logical. The ideas and concepts, that is, not the majority of us. :) Once I had exhausted his supply of videos that held my interest, I didn't visit the site for years, though I never forgot. I noticed that whenever I came across something that might have been covered by Lindy (you know the kind of thing), I found myself considering points he had brought to my attention in almost every case. A week or so ago, I revisited this channel, and was pleased to see it still active and receiving regular updates from the man in beige. I immediately subscribed and set to watching the new videos. And now I find myself relentlessly drawn to re-watch the stuff I had already been through years ago. Annoyingly, this has gotten in the way of other things I want to do. Well done, Lindy! Many of his suggestions have a sort of irresistible logic about them, making them easy to trust. Of course, that's not to say he's always correct (as the comment section is often quick to remind him), but he does seem to hit the mark more often than not, and I have come to rely on him to keep me grounded and to help me remember to consider the simple practicalities of everyday life when topics of war and bloodletting are broached. Thank you, Lindybeige. Good health and all that, keep it up.
I cannot believe I just found your channel, your content is exceptional and your personality is more than enjoyable. I'm looking forward to binge watching all of your videos!!
I think the pebble moved when you blew on it mainly because you also moved your whole body a little. Thanks for all the videos lately! You are staying true to your promise. Well done.
I would love a video comparing shortbows, longbows, and greatbows, as well as hand crossbows vs. light and heavy crossbows. Just love all this weapon detail business.
Speaking personally as an American who pronounces leverage differently and has another word for spanner wrench, I have this to say: we here find your diction quite charming. absolutely perfect for speaking authoritatively on medieval history!
The proper term to use for the ping-pong ball vs. stone example (yes, I said 'proper' and 'stone'... because you're British) is density, which is mass/volume.
'It's all a part of growing up and being British.' - Monty Python. Only just discovered your existence last week. Been having a lot of fun watching, some of, your videos since then. Thank you. Keep it up!
Around 5:00 I think you are looking for the physics and engineering term called buckling, which is dependent upon a thing called slenderness ratio. Look it up, I think that will further clarify your explanation.
A rock is a stone, but a stone isn't a rock. This isn't just a British way of calling them, it's the proper definitions of the words. Rock means A *large* rugged mass of hard mineral material or stone. While a stone is just any sized mass of hard mineral material.
The point might've been about how big a stone a rock is for Americans. I'm an American, and we call almost any stone, including pebbles, on occasion, rocks.
Howard Hill, the famous archer/hunter, wrote a book called “Hunting The Hard Way” years ago. He described making his own tackle in detail, as there wasn’t much commercial stuff available at the time. He described a method of grafting a section of heavier hardwood onto the point end of the arrow, which not only made the head/shaft connection stronger, but made the arrow heavier towards the point... Aiding in stability.
I realize I'm very late to the party here, but thank you so much for getting this right. I've seen so many people who THINK they understand basic ballistics come to all the wrong conclusions about both penetration and distance and also mixing up momentum and energy and whatnot, but this is just bloody brilliant. Good job.
It could conceivably go on forever at the same speed unless it hit something, so yea I'd say it would be quite effective. But I don't know how low gravity would effect tension, could you even fire a bow in space?
yeah elastic forces would still work, if you were in earth orbit though i doubt the arrow would achieve escape velocity and most likely would eventually fall or stay in orbit as dangerous space garbage. i can just imagine a future satellite being impaled by a rogue arrow fired decades prior lol
+raglanheuser The main problem is launching - no atmosphere means no aerodynamic stabilisation, so the slightest bit of spin and you're as likely to hit with the middle of the arrow as with either end. In orbit, things are even worse - over time, tidal forces would tend to leave the arrow pointing straight up and down, so eventually anything it orbits into will be hit lengthways rather than point-first...
I often rewatch so many of Lindy's videos. Not because I don't get the information the first time but rather...the way he expains things is so damn enjoyable!!! A piece of wood that would rather stay still frankly.
the sentence in the end screen is as always a masterpiece of its own;) And especially great after you think to yourself :" wait hit by a longbow at that range... that can be interpreted in three ways"
You don't need to involve momentum here, it only serves to confuse. What matters is that for similarly sized and shaped objects at the same speed, the air resistance is the same, but the heavier object having more inertia will not be decelerated as much.
+Peter Sand In this case, as the initial velocities are equal, the initial momenta are proportional to the inertias, so you don't have to involve momentum. If you do involve momentum you also, as you rightly mention, should involve impulse, which is another new concept many may not be familiar with and to explain it you will have to explain it by using force, which you would also if you were not using momentum. So using momentum is just one step further from most peoples prior understanding making your explanation just harder, not better.

+Peter Sand Yes, but inertia suffices quit well because inertia causes objects to keep their current speed. Regardless of whether it is 0 m/s or 45 m/s
+Quintinohthree Yes, I just thought that people associate inertia with static things and momentum with moving things. I may put a clarification on the description, but I fouled this video up enough with forgetting to mention that I was talking about arrows designed for maximum range at the start (when recording, I had a couple of false starts to the video, and left it out in the good take).
About the ping pong ball vs. the stone: Just want to clear something up - there is not more air resistance on the ping pong ball, it's just that the same amount of force on both objects will have a greater effect on the lighter object. The air resistance on both objects is the same, but Newton's second law is the thing at work here.
You are correct that more speed causes more air resistance. I meant that for two objects with the same speed and surface area, the force due to air resistance is the same. What I'm saying is that the properties of the material or the mass of the object does not lead to more air resistance, but the same force will decelerate the heavier object more. What you're saying is that if you give two objects some initial speed, and one speed is greater than the other, then that object will experience more air resistance. That is correct, but it's not to do with what I'm saying.
@@tilmanrotationalinvariant2257 I think air resistance on a smooth surface is independent of the material, but drag is proportional to v squared in turbulent flow which is the case with a rock, stone, pebble, or ping pong ball
I'm here because I use a longbow in my Dungeons and Dragons game and I wanted to study a little bit to play more accurately, so the reason might be silly... But I'm honestly amazed and speechless. I feel enlightened by your knowledge. 🙌 Great video! Cheers from Italy! 😊
I like to think about the first man to putting fletching on an arrow. He probably put it on as decoration or thought "Birds fly and they have feathers...I want my arrows to fly" so he put some on AND IT WORKED!
i think this would heavily rely on the scenario. in a siege on the defending side i suppose they just wouldn't shoot arrows then. but what about battles? i like this question.
Fletching size is also a factor in flight arrows, smaller fletchings have less air resistance so can fly further, but will be less accurate at closer ranges.
