Engineer: “are you going to fall over?”
Leaning tower of Pisa: “no, no I don’t think I will”
peculiar boast but alas Don't think 🤣🤣
Its pretty much how it is
2089: yep, it fell.
Why don’t they remove more sand so that the
Tower returns to its upright position?
@@juniorsir9521 Italy would lose one of it’s tourist attractions. But I guess the tower IS sinking AND leaning…
0:08 he has sunglasses but decided to take it off and looked directly at the sun
Haha
Lmao I didn't notice that
He didn’t look at the sun he looked at the tower
David Garcia i know
Javier Arroyo yes I know but he’s saying he’s looking at the sun but he was actually looking at the tower. I know that he needed his glasses, Don’t be so concerned
“We don’t make mistakes, we make happy accidents “ That lean has kept a million people year visiting Pisa. That’s a gansta lean.
Just put a bottle cap under it it will be okay
why didnt this have any likes LMAO
or 4 bottle caps
how?
HAHAHAAHAHAA
I don't get it
Love how they could've just made it straight, but decided to just make it still lean a bit.
To make their prediction of the tower falling one day come to pass. Anyway it wouldn't a tourist site if the fault is totally corrected. Once it still leans, it something for us all to learn about and appreciate.
it would never be perfectly straight because when the lean started during construction, the builders compensated by making the walls on the leaning side taller to level it out a bit, it's actually pretty visually noticeable . If it were straightened at the base, it would be curved a bit in the opposite direction of the lean.
@@smenard8388 It would still be a tourist destination. The tower's beautiful. And the churches are also beautiful.
Andre Newcomb I seriously doubt it would stay as popular as it is now vs being completely leveled. How many other famous bell towers can be named without having to do a web search?
The lean brings in tourists.
This tower is so famous that we always used in sample problems in trigonometry
I’m literally doing trig homework with the tower of Pisa problem while reading this
Lmao my math tutor showed my class an exam question that’s worth 4m with like 4 out of 7 sentences talking about the history of the tower(which is obv irrelevant but cool to know 😎) and the question asks u to find the angle of the shadow or smth. Actually I haven’t learn trigonometry but she just showed us for fun :)
😂😂
I did trigonometry problems of the tower in 1999✋✋✋
Just fold a piece of paper and put it under it
some glue and you're good to go
That's what you do for a wobbly table.
@@Marsalien100 well done, you got the joke...
i feel like this was inspired from the top comment XD
35 years ago, me and my girlfriend visited there. At the top of the tower , she said “ it’s scary, this is almost toppling.” I didn’t say anything, because I was also scared. After coming back to Japan, we broke up and never seen each other again. If I could see her again , I would say to her “ We didn’t have to be scared , it’s still standing .”
What impression did Italy and Italians make on you and your ex girlfriend?
@@nni9310
I was impressed with the beauty of the town and she was impressed with the kindness of the people.
Even after breaking up with her , I will cherish our visit there in memory as long as I live.
@@kenkishi8042 thank you for your response.
@@kenkishi8042 I'm sorry for what happened between you and your girlfriend
Woah
Isn't this an engineering mistake and not an architectural mistake?
Yeah I think so . Engineering deals with that
But what if it was only an architect without an engineer?
Engineers have commonly been around for about 200-300 years, the tower was completed in 1372
@@Rainolx still an engeneering mistake, not an architectural mistake
@@teles448 Geotechnical engineering was not understood back in those days. It's still having us scratching our heads from time to time. A similar incident occurred much more recently in South Padre Island, Texas. Unfortunately, that tower was imploded and the project was scrapped.
Engineering is an integral facet of architectural design. Arches themselves have to do with the properties particularly of concrete and stone in compression and stresses, the form itself and compression distribution forcing the entire underside of the arch closer together actually makes the structure stronger. So yes... architectural failure.
Shows how Humble the tower is, leaning forward with due respect
Maybe it’s leaning backwards due to back pain
It's Praising The Lord of Heaven Jesus Christ!

I don't know if I would call the leaning tower of Pisa a mistake when it's an 840 + year old engineering marvel that's in perfect condition.
It was never intended to lean. It is a mistake because the original engineers failed to factor in the type of ground they were building on, something that had been a known practice for over a thousand years before it was built.
D. They know...theyre point is....can something so miraculous be a "mistake"
@@ShanieCakesss I think the engineers that built the leaning tower of Pisa knew the rock bed was a sinkhole and that's why they placed massive footers under it instead

I was about to comment "why not just dig the other side of the tower to balance the lean?" Good thing it did happen.
It's dangerous.
@@Cheese9-11 But they literally did that to fix it
I thought that too. Also rigid hydraulic pressure on the low side. Most previous solutions seemed stupid to me as an engineer.
One day in Rome I was approached by a couple of young south Americans that asked me if the tower of Pisa was far from there. Probably they didn't realize that "Pisa" was a town located in another place.
I'm no engineer but relieving the ground of some of it's soil on the high side of the tower would have been my first choice.
Exactly, but Italy is famous for it's corrupt politicians and if Moussolini has a cement factory, you can guess whose gonna get the contract to try and fix it.... Even still though, the cement guys could have stilll extracted the clay from the high side!

I would love to know more about History. But there is one big problem with it. There is to much misleading information. Specially when they start talking about ancient civilizations. Egypt and others...

Down low too slow nerd
Why am I watching this? I can literally see the tower from my bedroom window. Help
i was bored due to lock down no other reason
I was recently in pisa, have you been to barbaldi?
Lovely
Lucky
Hope your house is not on the leaning side!
The point they missed here is that even if the lean angle is brought to zero, it will still not be straight. Reason; it was never built straight. Actually they tried to straightened it up during construction but tilting didn't stop and we got a wonder of the world.

Tower: leans
Italy: Amazing. We must keep it for 100s of years
Leaning tower of pisa: im getting this close
The last solution was brilliant. 🤣 It's like what my instructor always say, "the solution is very simple. Don't over think"
It's a shame how the tower gets all the attention, while the baptistry and cathedral are amazingly beautiful.
are those baptistry and cathedral lean?
None of it would get any attention if the tower wasn’t leaning
I visited the leaning tower.
It was incredible.
The tower hasn't collapsed to this day because the underlying soil is behaving like a plastic, hence is undergoing plastic deformation. As engineering geologists and geotechnical engineers we often use this marvelous to improve the understanding of soil mechanics.
Surprisingly, the following piece of information is missing in this video. This piece of information, I believe, can explain why the bell tower did not topple: "Construction of the tower occurred IN THREE STAGES over 199 years. In 1173, the foundations of the tower were laid. The tower began to sink after construction had progressed to the second floor in 1178. This was due to a mere three-metre foundation, set in weak, unstable subsoil, a design that was flawed from the beginning. Construction was subsequently halted for almost a century, as the Republic of Pisa was almost continually engaged in battles. THIS ALLOWED TIME FOR THE UNDERLYING SOIL TO SETTLE. Otherwise, the tower would almost certainly have toppled. Between 1233 and 1272 , the works resumed. In an effort to compensate for the tilt, the engineers BUILT UPPER FLOORS WITH ONE SIDE TALLER THAN THAN THE OTHER. Because of this, the tower is CURVED. Construction was halted again in 1284 when the Pisans were defeated in an important battle. The seventh floor was completed in 1319. The bell-chamber was finally added in 1372. [Source: Wikipedia]
The tower of pisa is like a tower falling down but the speed is -300
Let me get this straight, we don't even have enough technology today to fill a pothole properly and yet we are criticizing how they built a tower that is still standing today. I don't think so.
Civic investment is different from engineering.
To everyone saying that digging on the other side was your first thought: it was mine too, BUT there are other factors at play. I don't know a ton about it so I can't say for sure, but i assume the reason they didn't do this before was because of a lack of technology. To burrow into soil that has had a tower that heavy pressing down on it for that many centuries has to take an incredible amount of power--and, on top of that, to do it without destabilizing the tower with all the movement from said power. I don't know for sure, but i think it's a safe bet to say that the engineers weren't just plain stupid.
I would be very interested in a follow up video on why nobody did this before!
2:38 when she told you "look at my eyes when im taking to you" but you just couldn't do it.
London Bridge: "I am falling down"
Leaning Tower: 'Stand tall even when you are about to Fall'
When I first saw this in 1969, I didn't even want to step foot inside of it, to climb to the top! Shows you how pronounced, the lean, actually is!
“From-a this-a tower, you can see all-of-a-Pisa! Heeeeyyyy, look-a, I can see-a my mama’s house-a from here-a!” **hops up and down** “HEEEEYYYYYY, MAMA MIA, LOOK AT MEEEEE-A!” **tower tips** “Oops-a!”
Best informative video ever ...it provided everything I wanted to to ..thank you so much
Who else thought about digging beneath the tower before they mentioned it?
The final solution they came up with was the first solution I thought of. Lol.
"No one knows why it never collapsed"
That's the unique thing about ancient engineers, modern one won't get it😊

The funny thing is some old engendering are abandoned or we have forgotten bout them but but this one is still standing
Lol at the start of the video I was like “why not just dig a bit out on the other side and let it fall back” guess I shoulda Been an engineer
DemonCore44 same bruh
Engineers: *expecting tower to fall*
Leaning tower of Pisa: I can, but I won’t
Just remove dirt from the opposite side so it can balance itself.
Edit: never mind they did that.
They did it but they decided to preserve the tilt.
Imperfection is beauty
From the first depiction of the foundation, I figured the best solution would be to undermine the high side. Additionally, I would have gotten it down to between 2 and 3 degrees, installed friction piles for support then poured a cement slab under the tower to keep it in place.
I would have ripped it down and made a better one that isn't so boring and ugly
@@voidremoved Well then it's a good job you're not in charge of anything anywhere whatsoever and also do not live in Europe.
I would have left it to see how far it could go. Then rebuild it properly after it fell.
i can imagine how this tower rolls its eyeballs mocking these poor engineers lol
Go to Venice, every church tower's a leaning tower, you'd save the cost.
Going to Venice will cost you a lot more than going to Pisa, trust me
@@marcofava in the end I'm trying to say leaning towers are everywhere. Some tilt More some tilt less even this stupid tower isn't the most tilted.
crazy how they turned the pizza tower from pizza tower into a real tower
So it leaned but it still stands today?
"If it looks stupid but it works, it ain't stupid."
Remember when evil Superman straightened it out as an act of rebellion and then re leaned it to take back the evil deeds
“It was closed to the public”
He getting coronavirus early
I hate to admit it as an engineer but this isn't an architect's mistake. It's an engineer's mistake. The architect is not responsible for ground investigations (finding out how the ground behaves and its properties), a geotechnical engineer deals with these things.
Call me boring but I would not be going up that. 👀
I did, and nothing happened.
JEAN GRUEN fuck
lmao i’ve been up it so many times, it’s a surreal experience climbing up steps but about to fall back
When you actually stand outside of it, you would not trust it!
The leaning tower of Pisa wont fall due to something called dymanic soil structure interaction, which describes the relationship between the soils softness and the tower's height and rigidty.
How can you put so little information in a 7 minute video?
Structural Engineering Masterpiece
“Enough to prevent a collapse-“ oh ok that good
“For now” oh shit
They should dig another time underneath the higher side to make it 3°, otherwise any earthquake or natural disaster can crush this great tower down. The soil underneath the tower is ex-swamp region, so there must be a layer of semi solid soil that previously caused it to lean. Also it seems risky to go up in top of the tower, public access can be lethal if something wrong happens.
I took one look at it and thought, just dig on the opposite side so it straightens out. Did i just speed run years of engineering school?!
I was thinking that too, and I'm no engineer. Just seemed like a good idea.
Sometimes it's our mistakes that make us great, it wouldn't be what it is if it wasn't doing it's own thing. All It needed was a little help from it's friends.
Love Discovery UK & the leaning tower of Pisa
Im here because of the picture in facebook saying that he only bought the miniature of leaning tower of pisa for only 50 pesos 😆
Ancient Greek Architecture Mistake is still a beauty
Modern Architecture mistake becomes Tragedy..
Humans are interesting. For some reason instead of fixing it fully or tearing it down, we make sure that it is still leaning but not too much.
When i were in Tuscany, Pisa Tower were almost the only thing i skipped as it's nothing special. There is many leaning towers around the planet.
This has nothing on the leaning tower of Dallas.
I've never wondered why the tower leans..but it was next up soooo..here I am..ha
Glad the engineers didn't cause too much damage in the process of trying to 'save' it. China tried that with their wall and it turned into a disaster, hope this tower will stand for many more generations to come.
Thanks for an informative and educational video.
Thanks to all people who have pushed this tower in the pictures . See how so many push tilted the tower. Now we have push it from other side guys.
If this was built today, people would have just ignored it and said it looked stupid
Italy: known for pizza, pasta, and failure. 😳
The work finished in 2001 brought the tower to the lean it has two centuries earlier; presumably 1801. That lean (or worse) did not cause the tower to collapse for anothrt 200 years, despite rescue efforts that seems to have made it worse. It does not appear that it will collapse - at least not due to the lean - in the near future.
No cap, the first solution I though of would be to dig under the higher part slowly and gravity readjust it. Idk wtf all the other engineer were doing by using liquid nitrogen, steel cables, and cement. Literally the definition of over-engineering.
Its common when drilling because when you dig it starts getting water inside the hole youre drilling so liquid nitrogen freezes the water.
And they actually did dig watch the video again.
this is awesome because all the other wonders of the world are boring this has a sense of humour
So I always thought that the tower was built that way. I don’t understand why someone would go inside this building or why they wouldn’t take it down. “Let’s just wait to see how many people it kills because it made us a lot of money “
I am from Pisa and there is an entire church here that leans much more than the tower ahahahahah
Kevin Lee see holes in the engineering.
Such a nice thing to see on non-mma related channels.
Is that the shouty guy from the Cillit Bang commercial?
.. i have to admit that when i walk around that place , or drive around , i don't even raise my head for watch it ..
2:38-2:52I'd like to know where your center of mass is cuz those eyes oof😂😂😂
There are 2 other leaning towers in Pisa: S. Nicola and S. Michele degli Scalzi!
We are masters in amazing architectural mistakes!
Ever heard of the saying, if it ain’t broken, don’t go fixing it?
Maybe it can change the direction of incline and could be called floating foundation design to respond to earth change to reduce extreme change
The towel of pisa is historical they have to save but its also catastrophic
They should thank Professor John Burland of Imperial College who was behind the concept and supervised the removal of soil from beneath the foundation.
The leaning tower of Pisa is in the middle of a whole damn neighborhood? I thought that shit was in the middle of a field lmao
That part in Superman 3 with pisa brought me here.
The vertical line passea through gravitational CENTRE is going to base of the area of this building
And despite knowing this, a bunch of geniuses in sf did the same thing, and we have our own leaning tower
cable it up 2 cables and that will stop it alling also after time.instead of leaning and sinkin it will start to sink and straiten itself up
it was on a tilt, so the center of mass is slightly more away from the circular bottom, I say it would collapse at 5.8° - 6.1°
Till the center of gravity falls within middle third of the base the tower is unlkely to fall. unless the base opposite to leanining side is secured by anchoring with firm ground.
I literally thought of the last solution 3 minutes into the video.
