How to Make Amazing Tensegrity Structure - Anti-Gravity Structure
Vložit
- čas přidán 27. 08. 2024
- We made a sculpture out of wood batten based on the principle of tensional integrity (tensegrity for short), where all the strings are under continuous tension. The result is the impression that the sculpture levitates.
Tensegrity is a design principle that applies when a discontinuous set of compression elements is opposed and balanced by a continuous tensile force, thereby creating an internal prestress that stabilizes the entire structure. Puzzling physics structures that seem to defy the very laws of gravity.

Hey Bro, great work. I think if you use a transparent wire like tho ones for fishing the final effect can be even more impressive. :))
Yo, imagine this with a wire that's barely visible but really strong. I'm certain a wire like this already exists somewhere.

I’m choosing to do this for my school art final project. All I have to do now is glueing and that string!
lol i'm doing this for a school project too
Same
sorry for writing 3 years later but how can i describe this to the teachers?? can you help please its our pysichs project
Load carrying capacity of the structure is equal to the tensile capacity of the string. Since only one string is provided at the centre I think at maximum load the end string reaches only it's half capacity. But aesthetically it is good
Imagine, architect make a building with this concept
Theres bridges like this but with a more complex design
@@steamhelsing9440 what?? 🤯 Do u mind share a link to it?
that would be very cool, but i dont think its stable enough as it scales up to handle the type of load that a building entails
en.wikipedia.org/wiki/Kurilpa_Bridge A quick wiki gave this bridge in Australia
XDDD
Of course there is no limit to the length of the strings, so you can hide the lower assembly; if you combine this with using transparent wire, the effect could be quite mysterious.. Great build. I like the simplicity of this! 🌟👍
What are the dimensions of the wood lengths?
@@tommystump1517 The two sides are made to the same dimensions. The long arms are 8 1/2 cm (7 1/4" - 7 1/2 ") The wood between the arms is 5 1/2". The center piece that runs to the small center piece is 8", the small piece that is connected to the other small piece with string or wire is 4" in length. I hope this helps. Best of luck.
I built one based on this video. It works beautifully. After setting about the right length for the center string and glueing it in place, it's simply a matter of getting the right tension on the two long strings. First, I glued the bottom of the long strings in place. After they dried, I put the other end of the strings through the holes at the top and used masking tape to hold them in place. Then, it's just a matter of achieving the right tension on both long strings to center the structure and then glueing them in place.
"....... its just ......"? Are you kidding? That's like saying "just jump high enough and you can dunk a basketball".
I have, since my other comment, made several of these and I see your point. I aged about two years, though, achieving the right tension. Also, I use fishing line for transparency, which is not very suitable for using with glue. I insert the toothpicks in enough to hold it up and then finish pushing them in after adjusting the lengths.
@@normanacree1635 Yes, it's a frustrating process. The fishing line started to stretch after awhile and threw the balance off. I've used other kinds of material, but it isn't the same as the transparency of fishing line. 'sigh'

The centre string provides tension and the other strings provide balance.
Welcome back! Long time no see!!
That's pretty cool! Thanks for the instructions!!

After watching this the first thing that came in my mind is, maybe I can fulfil my dream of living in a floating house someday.
That would suck cuz you'd need to have a helicopter ride down if you wanna go anywhere
Retractable ladder?
You would have to build your house in a location where there is absolutely no wind. Might work on the moon.😊
If I'm correct the way it works is simple. The smaller thread(out of total 3 threads) in the middle of the structure is the one bearing all the weight, so it does not defy gravity because the [bottom wooden support frame]'s/(or the frame which touches the ground)'s connect point to the "small thread" is higher than the connect point of the "upper wooden frame" which seems to be floating in air but is actually hanging from bottom frame through the "small thread". The other 2 long threads are there to keep the balance so that the upper frame doesn't fall to a side.

Man, next time I build something in carpentry I’m building this very table. The design is so simple, yet so fascinating.
Any news about that table?
@@HM-2011 Also waiting on pins and needles for a response!
The top structure is hanging by the middle string. Because its centre of gravity is towards the top, it tends to rotate clockwise/downwards...this causes tension in the 2 strings which are preventing it from toppling. Balance is very important in this design....
I have never seen the term 'balance' used by engineers to describe how this works. 'Tension' and 'compression' are the two terms that explain what is going on. If you look at more complicated things like bridges (design only at this point), you can better visualize the tension and compression factors at work. Google 'tensegrity bridges'.
It has to stay balanced. If you bump it a certain way, then it will topple. Why do you think he is being so careful?
hi! sorry for writing 3 years later but this is our physichs project can you help us? how can we describe this to our teacher??
@@normanacree1635I see no compression anywhere. Just tension in all the three strings. The clever design converts the downwards compression in middle string to upwards in the two long strings. They balance each other out.
Yes balance is very important here... Or it becomes unstable. You must be able to balance the tensions or it will simply tumble
Use chains adapted to the proportions of the sculpture (for the realistic miniature effect), it'll greatly enhance the law-defying effect!
With transparent nylon wires, it blends in slightly yet remains quite visible (unless camera tricks), hence it's obvious the wires are trying to hide something. The counter-intuitive effect is lessened as it's hinted off that there is a trick. Nylon fiber wires are commonly used to hold light weight things with a purpose to look like it's not there. Hence the spectator knows it's doing something despite not necessarily figuring out what. It's enough to kill the major part of the wow effect of a law-defying trick.
With more "serious" wires, like chains, the mind faces a more appearant counter-intuive behaviour of the two platforms and their ties -the chains then look like they're actually trying to hold the upper platform from taking off while actually intuitively looking like it should drop down. That's when you the counter-intuivivity strikes in and the effect is glorifyied as the chains don't look like they're doing what they're doing
This kind of presentation is what turns a nice trick into a magic trick. It's not easy to explain but it's very effective :)
Do you know of any simple mechanism to tension the chain? Thanks
Is there a relationship (ratio) between the lengths of the wood pieces or any specific lengths to avoid or try to get?
At first, that's what I thought.
I'm sure you can make something similar to what's in the video.
Just make the top and bottom pieces the same size and I would think everything will be fine.
I'm actually getting ready to make a small "model" and experiment first.
Before I use any of my walnut or cherry wood I have stock piled.
Just take your time, and I'm sure you can do it with out any major problems.
I like how he gently places something on it lol
I've built a couple of tensegrity structures like this,. The most important thing is to have some way of tensioning the wires/chains/whatever after construction. In a diy environment the chances of getting the tensions right first time aren't great - not if you want the top to be level, at least.
That said, once you've managed it, you WILL impress your friends and families, no question. Their first question is invariably "Is it a trick?"
Is it a trick? I tell them 'no', it is magic.
Jacky, do you have any suggestions for an adjustable tensioning mechanism?
Length of wood pieces.
Nice work! This looks very cool! I also made one, but there is no rope in the middle, "anti-gravity" succeeded!
wtf is gravity?

Finally a video after one full year!!!
Thanks bro..
I tried and I done its sucessful working antigravity ..
Tensegrity tables: They're objectively awesome!
Are there plans/measurements etc... available?
It’s a simple illusion-the centre wire holds the weight, the other two stabilise.
Was gonna comment that, I just figured it out to lol
Doesn't mean it doesn't look cool
Cheers einstien
Hi, can you give me the measurements of the wood battens?
I always used sky hooks to build things like this. You learn something new every day.
If you added 2 more long strings to the other 2 corners - so all 4 corners had 1 long string each, instead of just 2 of them - it would make the structure a lot more stable, and you'd still have the tensegrity effect...only string between the 2 wooden structures -- but it would be impossible to just knock the whole thing down by pushing on it in the wrong direction and collapsing it. If you have like kids or pets or *both*, then with only 2 long corner strings, that thing IS *coming down*....but with *4* long strings, that are each under tension...you have a pretty "solid" and stable structure that you can sit something heavy on top of like a it were a regular table, and not worry (too much) if a crazy careening cat and/or wild-eyed dog and/or sugar-fueled toddler all go *crashing* into it.
I like your idea. However, the fun and magical part of this is using only three strings (I used thin wire). I put it up on a high shelf so it can't be easily bumped.
Just knowing this is possible gives me a weird glee.
Thank you.
The short string in the middle is the suspension point carrying the weight of the upper structure. The two long strings are balancing the Moment of the upper structure due to its unsimmetry.
The only one thing that holds it up is that one string in the middle. So am I wrong to say that the whole structural strength of this is based on the tensile strength of that middle string/rope?
@Cosmo Genesis holds it up, i doubt it. Stabilises the structure, yes.
The middle string is the source of almost ALL of the support until you begin setting things on it that upset the balance of the structure. Then the outside strings are responsible for keeping it from collapsing. The center string will always have the most force on it, I believe.

Device to end the creation of Nuclear waist.
Electric Generator Design that's powered by it's self & perpetuates more electrical current then is needed for it to run continuously on it's own.
Step 1: calculate how much energy you need pumped into an electric motor to make a vertically positioned circular platter with magnets in-bedded horizontally around it's left side and right side (so there pushing force is pushing out sideways relative to the vertically spinning disc) to spin as fast as you need it to. Also better to make sure these magnets are shielded around their sides & back with metal that has high permeability so the magnetic field they are emitting is focused fully out sideways. :D Step 2: Calculate how many sets of copper coils you need to be interacting with magnetic fields to achieve this & to perpetuate more electrical current flow then is needed. :D Step 3: Build a round horizontally positioned platter covered in all these copper coils pointed down that does not move (Is stationary) :D Step 4: build a round platter covered in powerful magnets pointed up that can spin and place it directly under platter with hanging copper coils. :D Step 5: Position the vertical platter that is motorized close to the horizontally positioned platter covered in magnets pointing up so that when the vertically positioned platter spins the in-bedded horizontally positioned magnetic fields slam sideways against the edge of the horizontally positioned platter causing it to spin. :) Step 6: Make sure enough of the copper coils are feeding their electrical current into the electric motor and the rest of the copper coils are linked into a set of rechargeable Battery's placed in the closest most convenient spot. Step 7: Build a duplicate setup of horizontally positioned discs with hanging copper coils and disc with upwards facing magnets and assuming the first set of discs are positioned to the front left side of vertical spinning disc, position the other duplicate structures to the front right, the back left and the back right of the vertically positioned motorized disc. As the vertically positioned motorized disc spins the horizontally in-beaded magnets will now hit into all 4 horizontally positioned discs causing them to spin. so you will effectively be using the spin of one disc powered by one electric motor to spin 4 constructs that are each generating electrical current. now build this whole setup multiple times over and use the current perpetuated by it to power up scaled electromagnetic generators that are equal to or more powerful than the ones used in a nuclear power plant. You will now have a device that is self perpetuating off of it's own electrical current perpetuation and no nuclear waist to worry about.
I say, "Start building one".
Excelente trabalho! Parabéns 👏

@@OAKAdventures , you don't make a house ,

So the answer you gave is wrong
Something that is going to fall over, scrape up your shin and crush your toes?
@@donepearce , How exactly ?
The 3 strings or in my case Log chains are like a 3 legged stool , but I'm going to add two more strings or Log chains on the other end , so it will have chains on all four corners and one in the middle ,
The chain in the middle can't pull down and the other four chains will be pulling in the opposite direction so only a little side to side movement ,
I broke my bandsaw blade and I'm not going to cut metal tubing with a hacksaw , so I'm going to be delayed in making it , and I got hammered silver paint to paint it with
@@jimthomas777 Then you are making something different. It will work
@@jimthomas777 Using the extra chains will make it more stable but less mysterious. Lots of examples of table on CZcams.

Very cool. Good ideia.
Il fallait y penser. Très belle réalisation. Chapeau.
If I use 4 side string instead of 2 then it will be able to balance long object too, which centre of mass is not in base .🤔🤔🤔🤔
I would use fishing string for a cooler effect :)

Thank you for these plans. I am going to cut the wood to size and then have my grandchildren each make one of these.

Pretty easy really the middle chain thing is hanging so gravity is pulling it down. The other 2 side chains are being pulled up by the top and just to keep the top in place. Image if the top wood wasn't there the middle chain would still be hanging down

The length of short rope in the middle should be 95mm (not 92mm)
Alexander, is this how you arrived at this conclusion? The 2 center posts of each assembly are 205mm each x 2 = 410mm. Subtract the length of the 2 long strings on the ends of the structure, 315mm each, and that leaves 95mm, correct? I'm going to attempt a build and realize the 3mm difference in your answer versus the directions can make a big difference. Thank you.
@@in2rock275, exactly. But while 95mm is mathematically correct, it might be that short middle rope should be shorter as it holds main load and stretches more. You should find it out with your experiment, good luck!
You will avoid some heartache if you don't worry so much about the lengths and simply insert way more string than you need and insert the toothpicks just far enough to support the object temporarily. Adjust all three strings until the structure supports itself and secure the toothpicks, making sure not to change the lengths in the process. Cut off the excess string. Measuring and cutting beforehand means that if you miscalculate or make a cutting error of just 1 or 2 mm, the structure will not stand.
@@normanacree1635 Yes, that's how to work with strings. Especially if strings can stretch. My comment is about the final size, just to make all sizes consistent, and that's not a big deal, real experiment as you described will make it work of course.
Interesting...I wonder if this concept would work building in an earthquake environment area to help suppress the damage being done.
Полка супер !👍
Thank Buckminster Fuller, father of the geodesic dome for this among many other radical inventions.
Its an illusion. The top piece is not suspended, it's hanging by 3rd shorter string. 2 longer strings give lateral stability.
Physics still rules.
Cool mobile idea. I want one.
An interesting product, unusual solution!))
Simple équilibrage des forces 👍😊
Beautiful and wonderful ideas
What kind of witchcraft is this? But seriously, this is amazing. My brain doesn't understand how it works but I am fascinated by it.
Upper piece wants to fall down but the small wire in the middle is too short to let that happen and that part is essentially hanging by that wire
And the upper piece is heavier on the floating side (with the opposing side's 2 long strings holding it up), or else it would rotate and collapse on the 2 long strings side. Look at this chart and you'll know everything:
` ~ _| ---|[ -- __ __|_ ` - . - ` |__ ` ~ _| ---|[ -- - __ ___|_ ` . ` |__ |` ~ _| ---|[ -- __ _|__ ` -- ` |__ ` _| ---|---[ -- - __ ___|_ ` . ` |__ |` ~ _| ---|--__--[ -- __ __|__ ` - . - ` |__ ` ~ _| ---|__[ -- - __ ___|_ ` . ` |__ |
There hast to be a great use for this principle. Just need some time...
wow, its amazing, great job 👏

Amazing idea I also made one after watching this...
If you want to put something like a pot on it, you will want a screw at each joint. Otherwise, the glue will hold just fine IF you use good glue.
