Never forget what you see inside a line, snorting teaches something. You obv know that already, but really... look at the structure you snort. ;) Architecture and drugs can be a tool towards understanding.
We just went to the Da Vinci exhibition and had a go at building this, the end product was about 3ft long made out of 2in thick poles. We built the end sections and then wedged the middle bit together LOL. It was a bloody mess but got there in the end. I totally see how we should have done it now doh!
+lytken That's what I was thinking. It would have to be supported during construction, either from below or by a crane on the side you started building from. If the former, the obstacle isn't really impassible. If the latter, you would have to support the far end with a rope and build on the near end, pushing it out toward the far side.
+lytken You would lay large tubes in the river allowing water to pass through them. Then pile dirt or sand on top of the tubes and use plastic tarps to prevent water from passing on the outside of the tubes. Once you have a mound of dirt or sand across the river with the tubes running through it to allow water flow, you lay the bridge pieces on the mound. When the bridge is assembled, you remove the plastic and allow water to pass on the outside of the tubes, washing away the mound. When the tubes are exposed and all of the dirt has been washed away, you pull the tubes out of the water off to one side of the bridge.
+Joe Jones with tubes in place and sand over it you've just created a bridge just to end up using it to cross another bridge then destroying the original bridge....
Use materials that are lightweight but strong, then build it before moving it over whatever you're trying to cross. You could support it on the other side by using ropes wrapped over a branch.
+jdsol1938 Yes, in Sung Dynasty (960-1279CE), Chinese has already built wooden bridges in this way. A picture of the bridge is painted in the Sung painting 清明上河圖.
It's a fucking Arch bridge, it's not new and the Chinese didn't invent it or the arch concept for that matter. Romans used it 1000 years before the Chinese did and Greeks invented it 2000 years before the Chinese did.
Is it possible to calculate the force on the joints? Particularly how much stress is occurring if I have a weight hung from the center with a mass of 10kg =~22lbs
Funny it reminds me of the Rainbow bridge in China it uses the same system and is in use today. Oh Josh Bowes it's not fake look it up. I think the Chinese even used this system before Leo (but I could be wrong about that) but I believe Nat Geo did a special on it some years ago. Sorry it was Nova and it was over 900 years old.
This bridge was used in Song Dynasty China, 500 years before DaVinci. Marco Polo, visit China, and probably took the idea and called it European. European colonizers go around pillaging, stealing ideas, and erasing cultures around the world.
Pretty cool but you have to build false work under it; much like the new Oakland to San Francisco Bay Bridge ( which is self supporting as well ). SO if you are going to span anything significant you need material that and equipment strong enough to support the thing cantilevered as you lift it over your span. SO, I don't think this was ever used by an army to immediately cross a stream or something.. It's still cool though
So, Da Vinci copied the Chinese Sun Bridge, now that put into question of all his ideas. where they his inventions and by some chance his line of thinking was the same as the Chinese thinking, or did hear about the Chinese inventions or see a drawing.
It would be awesome if you didn't have to cross the river to set it up, or as it appears, set it up while in the middle of the river as you lengthen it. It's not that complex its just weaving, as humans have been for thousands of years before. Engineering is just taking what you know and applying it to new situations. But mostly math.
lol, everyone who challenges this doesnt understand physics and gravity. however this would never work in any "real world" application due to the variables you dont have yo account for when u make it 1/120th scale. like the other commenter said, how would you assemble this over a 20ft gap using 6 ft sticks, next, when u place weight on it and it begins to bow(flex) and u pass a fulcrum point it will fall apart from the middle out, dropping u in the river or chasm, and lastly if all 4 corners do not meet the ground flat(aka if u dont place the bridge inside of a perfect rectangle, which you will never have in any "real-world" application) then the structure will be just as unstable(not to mention how stupid trusting your safety with nothing more tha an elliptical notch is xD). LOL, not to bust anyballs here but the triangle is the strongest isometric shape for a reason, henceforth the reason why bridges are designed the way they are, and also why no one trust suspension bridges like they did in the 50's-60's. a very good lesson for anyone interested in structural enginering then.
swimming will be much less frustrating, put all the stuff you are carrying onto a wooden ox, invented 12 centuries before Leonardo was born. (Note: the wooden ox flows for you)
...Hell....how Einstein was right when he said: Two things are infinite, the universe and human stupidity, and I am not sure about the universe!If you have doubts about who I am speaking, is about you all, or most of you!
Oh I don't know...this carpenter extraordinaire allowed his grandson to walk across the one he built, using the Chinese designs which date back, like, a thousand years. ua-cam.com/video/PYkgEf3eWqA/v-deo.html
Greatest genius of all time. The only genius who was at the very top in more than one field (art, science and engineering).
4:10 you're snorting it wrong
-NineTailed- dude im dead now
hahahahahahahahahahah

LMAO, thats hilarious
I just read this 5 yrs later, 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
bridge is neat design, how many man would it take to lift a bridge spanning a river? would they have to cross six times like in the video.

Thank you for sharing such an ingenious piece of art..
Wow incredible! He can do a structure made out of sticks! Da Vinchi is a genious!!!!!
I made my own bridge with chopsticks. I notched then pretty well but it still felt like I was playing pickup sticks. This guy makes it look easy!
I believe they would tie the ends of long logs to short ones, so they don't come apart while lifting the logs up...
Another excellent video and very clever design, could you keep adding pieces to make the bridge bigger?
still can't see how you would assemble it over a ex. 20 meter fast moving deep river
+lytken That's what I was thinking. It would have to be supported during construction, either from below or by a crane on the side you started building from.

and how did you get to the other side before the bridge did ;)
A bridge for Ants? It needs to be at least three times this big!
I thought the same thing! Haha!
Note* the bridge does not magically put it's self together in thin air...
Oh.
I thought that how all bridges were made!?
Garrett Hawn-Pangrazio trust me, it blew my mind too
they use crains to lift up the pieces to build over the water
how to cook asian eggplant
weren't the Chinese using this style of structure much earlier ?
+jdsol1938 Yes, in Sung Dynasty (960-1279CE), Chinese has already built wooden bridges in this way. A picture of the bridge is painted in the Sung painting 清明上河圖.
thank you for the informatin
+William i-am the more weight put on the bridge, the more stable the bridge is, also the design evenly distributesb the weight on the structure.
Jonathan William also higher clearence

Is it possible to make this bridge with round logs without notches?
when I was 10 years old I used to construct such things with matches
Ok Leonardo, we believe you....
jamie darren leonardo was older and had no matches you salamon
😂😂😂 dead on Da Vinci
What about the wind if high altitude?
Is it possible to calculate the force on the joints? Particularly how much stress is occurring if I have a weight hung from the center with a mass of 10kg =~22lbs
Un bigliettino un
where do you walk? just try to avoid the holes between the supports?
How much weight it can withstand??

Is this considered as an arch?
Cool! Now gota build one!
I think you should make it wider at the bases and narrower at the top. You made the opposite and it would be less stable sideways.
Pretty cool but you have to build false work under it; much like the new Oakland to San Francisco Bay Bridge ( which is self supporting as well ).

Isn't there a covered bridge in Virginia with a similar design philosophy?
can you make a circle out of this
but then the bottom would have no pressure because the curves would be facing upwards and it wont work
@@HienVu-ow7cy The bottom will get the same pressure actually. But the sides wont, because they‘ll be stressed by a vertical force
Pretty interesting
If you guys don't like it don't coment and watch another movie. It's Leonardo da Vinci.
how would you make this in real life tho when trying to cross a river for example?
Rainbow bridge was invented before this. Same design in china 12th century
So, Da Vinci copied the Chinese Sun Bridge, now that put into question of all his ideas. where they his inventions and by some chance his line of thinking was the same as the Chinese thinking, or did hear about the Chinese inventions or see a drawing.
isn't every bridge kinda self-supporting?
some have towers supporting it or ropes but this uses weight and balance to hold its self togrtther
It would be fun to make your own out of a dowel rod
Still can't see how you couldn't create a presentation assembly in inventor...
It would be awesome if you didn't have to cross the river to set it up, or as it appears, set it up while in the middle of the river as you lengthen it. It's not that complex its just weaving, as humans have been for thousands of years before. Engineering is just taking what you know and applying it to new situations. But mostly math.
Some other videos shows an easier way of assembling it.
何回か作ってみたが、面白い！。
Good point, I was wondering the same thing...
Класс! Мне очень понравилось - перспективная штучка.
scale that up to an eighth scale....notice how high he had to lift to assemble.
Looks like he tried grabbing a broken ladder and said "ah-ha, Now its a bridge!"
come how got here from watching a LoL montage lmao i love the internet
Impossible to build across a river .
unless you use crains to lif them up
Maybe roping up the joints would help
Except this was not his design.... this was perfected in China as the rainbow bridge...
are we sure that DaVinci didnt just come from the future and just teach what he could with what he had to work with?
It reminds me of THE CROWN OF THORNS
how?
"traditional" Chinese wooden arch bridge de vinci stole the ideal
Not a bad vid, but it could use a little soundtrack.
+Chris C. yeah sure bieber wud work just fine in background... lol
right!! Now lets see it assembled across a 20 metre wide torrent of fast flowing deep water.
One way to look at Da Vinci's concept is to think positively and devise a method to make it work in practice; naysayers need not apply.
You couldn't assemble it across a river.
I think people would rope the joints then pick it up from one side but honestly I'd have to see that.
