📼Video Summary:
The clock tower was built in the 1840s and 1850s but it wasn't until 1862 that the clock was fully functional. It has been ticking almost non-stop now for almost 150 years! There are stairs that go up the very center of the tower and they are also putting in a service elevator in one of the open shafts. The Clock Room is where the mechanism is - this is referred to as the Clock Movement. It's made up of 3 gear trains - the Striking Train, Going Train, and the Chiming Train. The Going Train turns the hands on each of the four dials, the Chiming Train rings the 4 quarter bells, and the Striking Train is responsible for ringing the largest bell "Big Ben". During the video you'll learn more specifically about the parts of the Going Train: the Escape Wheel, Gravity Arms, and the Pendulum. The bells are located above in the Belfry. Every half hour bells will play at least part of the Westminster Chimes. At the very top is the Ayrton Light - used to indicate when Parliament is in session down below.
The renovation that started in 2017 is set to complete in summer to 2022.

Jared Owen, could you please make a video on the Ford Model T engine? I want to see how it works in 3D!

Happy birthday to Queen Elizabeth II :)
It's a masterpiece of work. Absolutely incredible video.
But who came up with the idea of the Clock Tower?
What software did you use for the modeling and animation?
OMG Jared! It's been some time since you last uploaded a video & I was sure you were working on something incredible. I wouldn't have been able to observe all the different aspects of the tower myself even if I was there with full access of it. The level of detail you you have on your animation is just out of this world. To have an eye for such detail, for eg. giving un-uniform roughness to the surface of the Big Ben bell is next level. You always blow away our mind with your animation. Kudos to your hard work 🙏🙏🙏
It's fascinating to see how pennies can affect the timing of such a huge machine. Loved the video as always.
Thanks for watching😀
@@JaredOwen can you please make a video about typewriters. If you do. Please do a Smith corona or a Olympia travreller de Luxe!
You spoiled the video
@@lewissuckling Oh, c'mon. Gimme a break. It's not like French Fry gave away the plot twist of who murdered Big Ben.

Amazing to think that this clock has been ticking away for longer than a lot of modern countries have even existed.
Alot of them exist due to legacy of British empire
@@Anonymous-qb4vc And a lot of them don't due to the destruction of the British Empire
@@sujitbala1492 world was way worse before
@@sujitbala1492 The British empire did some good things and some bad things. Too often though people only focus on the negatives. As for you presumably in India, even Gandhi acknowledged the benefits to British colonialism and said that the empire was benign. We built your railways and the system we developed became a model adopted by many countries. I was born in the 80s and am not responsible for what my country did before.. unless you are one of those who believe in the "sins of the father" argument. No more replies from me to you, you are too ignorant. Sorry. And I'll add something; while your prime minister allows Islamophobia and Hindu-extremism into politics in India, and Muslims are beaten by vigilante gangs or their citizenship is threatened to be taken away, I won't take lectures. In many ways India was probably better off under the British!
Whilst in the UK 1850’s doesn’t seem so old. My local church was about 900 years old and it wasn’t even really noteworthy.
I went up into the clock tower in 1966 on a primary-school (5th-grade) visit to parliament. They timed it for 12 noon. I remember the oxidised-black Victorian pennies, originally shiny copper-nickel, used to regulate the pendulum. It was dusty, untidy and cluttered with equipment; they did not let us go up into the light tower. There is a jail cell one-third of the way up the spiral staircase for errant members of parliament, unused since the 1880s. The 1960s was still an innocent era: nowadays the tower is closed to the public for security reasons. They did a great job of restoring and cleaning the exterior, so it can be seen through Victorian eyes for the first time in a century and a half.
I'm sure this has already been mentioned, but the restoration work is complete and the tower and clock face look magnificent. I've seen this tower throughout my life and the overhaul has brought something new to it.
It really does look magnificent now it's been restored.
I saw it this week, the restoration looks wonderful. Remember when London was so smoke-ridden it almost looked black!
@@LAGoodz ... I do remember those days, most places were like that then from the smoke of coal fires etc as you say. Thankfully places are cleaner and look lovelier for it nowadays.

Imagine all the trial and error 😵
@@caibruce2161 ouch imagine the error
This was an era when people actually developed the natural intelligence they were born with through hard work and dedication. The people who designed and built this clock tower were called engineers. This clock and tower were not built by trial and error. It is all based on mathematic calculations. The sad news is that today most people rely on "smart" devices for their information. The problem with this is people have lost the ability to develop and think with their brain.
Europe is home to the largest watch making company
Learning about how things work is really amazing, you gotta appreciate how people first learned to make things like this, roller coater, other famous buildings, and products we use and don't think too much about.
True.
🎉🎉🎉🎉🎉🎉🎉 big ben
Making these 3d models are tough and time consuming. I really respect and admire what u do.
Fascinating! I lived in London 15 years and didn't know most of this! It's basically a giant musical box 🎶
The pinned cylinder technology later used in barrel organs, barrel pianos, and cylinder musical boxes, is belived to have originated with musical carillons (bell towers) circa the 1200s.
The oldest barrel organs I know about documented are from at least a century or two later (the oldest extant barrel organ I know about is the Salzburg Stier from I think the 1500s).
Barrel pianos probably don't date from earlier than the 1700s but I'm not sure.
Musical boxes (with combs with tuned teeth) only date to the 1790s at the very earliest, the era of the original patent for tuned steel teeth.
Cylinder musical boxes, barrel organs and barrel pianos were generally mass-produced in the 1800s and 1900s. It is extremely unusual to find an existing one made before this time (almost impossible for musical boxes), due to those of this earlier period being mostly handmade limited production one-offs (not catalog models), built for royalty, nobility and the church. It was only with the rise of the middle class, and the advent of mass production etc that more people could afford these for home and commercial purposes.
Not only did I learn how Big Ben itself works but I also learned how to understand the chimes coming from Clock Towers. Thanks Jared!
You mean, that the number of bongs denotes the hour? That's fascinating; I've known it since childhood, but of course someone must have told me that once! It hadn't occurred to me that there are people who didn't know it - but then so many other things I increasingly find people don't know, like how television works, or how a still film camera worked.
@@G6JPG Yeah, by the time I came around, they weren't as needed as they were once so it wasn't even really there to learn.
I’ve said it before but this is one of the coolest TH-cam channels!
This is a guy that deserves millions of subscribers and millions more!
Thank you! Hopefully that sub count will keep going up🤞
@@JaredOwen Please make something related to railways.
Ben yes no ugh hohoho
I just discovered your channel and am loving everything I've seen. I'm British (though I now live in Europe) and once used to help wind my village's 500 year old clock. Your fantastic graphics and accompanying commentary has added to my understanding. I cannot imagine the work you must do to create such visuals, but I truly appreciate them. Keep up the good work! 👍😃
Mind Officially Blown. All my life I've never known exactly how a pendulum works, not even after owning a pendulum clock for 20 years! Thank you! I've watched a few of your videos and find they are very clear and easy to understand. You're doing a great job.
Such a cool explanation of Big Ben! Really makes me want to plan a trip to London. Definitely one of the coolest channels on TH-cam!
Love your videos!!
The coolest city too!
A typewriter video will be most welcomed too.
Urgent attention needed! ✌👉 The Connections (2021) [short documentary] 💖✌
May I also suggest you get outside of London too.
London's amazing, but it's pretty different to the rest of the country.
Go see Portsmouth and Southsea
And Brighton and Poole
Visit Cornwall
Go up North to see Manchester, Liverpool and Leeds.
Rent a narrowboat and traverse the Rochdale Ring canal system (we recommend Shire Cruisers)
Moor at a pub (yes really) and go in for a ploughman's and a pint.
Go see Wales and Scotland.
Edinburgh and the fife area.
Hunt out interesting pieces of historic British engineering and the industrial revolution, tours and sites and museums, hundreds and hundreds of years of being the science, technology and industry center of the world.
Good luck!
The escapement has two purposes. It takes timing from the swinging pendulum to release the weight that drives the clock, and it feeds an impulse back into the pendulum to keep it swinging.
Also, one might expect that adding coins to the pendulum would increase the period by increasing the swinging mass, but the effect may be counterintuitive. Adding coins does increase the mass, but it also raises the center of mass closer to the fulcrum which has a greater effect and decreases the period (it gives the pendulum a little push).
Yes
I was wondering about the pennies, it seems counterintuitive
it is not counterintuitive since the reason coins were added in was not to increase its mass in the first place at all but to do the complete opposite, which is to purposefully raise its center of gravity as you said therefore reducing its effective length to cause it to swing faster.
@@ravelisland Oh, I missed that. That makes sense.
The intuitively expected effect (adding material lengthening the period) would occur if the material was added to the bottom end of the pendulum.
Well I'll be damned. I had no idea Big Ben was actually the biggest bell and not the tower itself. I've always dreamed of visiting London and the Palace of Westminster in particular. I really love your videos, I learn so much from them!
The bell Big Paul in St. Paul's cathedral is a bigger bell in London. Big Ben is 13.7 tons in weight, Big Paul weighs 16.7 ton & the biggest bell ever cast in the UK. 🇬🇧
Hi Jared.
My grandson Liam and I really enjoy your great videos showing how things are built and operated. Great work. I just returned from a prairie vacation in which I visited some old wood grain elevators. At one time these prairie sentinels were the spiritual and cultural center of agricultural communities. It occurred to me that these large structures, used for accumulating grain from prairie farmers, would make a good subject for one of your videos. Just a thought. My grandson asked me how they worked and I struggled to explain to him their operation. At one time they represented the highest technology of their day.
Good video but, to nitpick, Big Ben is not located “ in the city of London” but in the city of Westminster or “in London” ( a metropolis comprising two cities and 31 boroughs). The “city of London” is the square mile original walled city which is some miles east of Westminster, its palaces and the Elizabeth tower/Big Ben.
There's an episode of NCIS where Ducky explains he's going to London but he won't be IN London. Yeah, it confused the rest of crew (and me too watching). I don't know how confusing it is for folks not from New York City, but we have a possible point of confusion too: So, we have New York City, which consists of 5 boroughs and counties. The confusion can occur when one says New York County but might mean New York City. NY County is actually the Borough of Manhattan. The other 4 are Queens County (same with its borough name), Kings County (Borough of Brooklyn), Bronx County (same for borough), Richmond County (Borough of Staten Island). The borough names are generally used for regular maps and the county names for political info (e.g., maps of poll sites in Kings County). Sorry for the tangent.

@@bikeny I grew up in queens and didn’t know this lol
That's not nitpicking at all. It's simply fact. People who post videos should be more careful.
Approximately 2½ square kilometers
The fly fan doesn't slow the rotation of the escapement wheel necessarily, but is meant to keep forward momentum on the escapement wheel so the legs don't bounce on the gravity arms. The fan is attached to a one way clutch which allows it to continue moving forward slightly after the leg of the escapement wheel lands on the pallet of the gravity arm.
Just to let you know that the Clock tower used to be called St Stephens tower which probably got it's name after the Chapel was destroyed by fire in 1834. It was renamed after the late Queen Elizabeth after her Diamond Jubilee in 2012.
Great video! Just to note - you mention towards the beginning of the video that the clock tower can be seen from Buckingham Palace. The Ayrton Light at 5:30 was actually installed specifically so the Monarch would know when Parliament was in session. It was an addition requested by Queen Victoria. You didn't make the link in the video but I think others may find that interesting :)
Also, whilst the Abraj al Bait may be a taller structure, it is not a clockwork mechanism so I'm not sure it's fair to say it is a taller clock tower than the Elizabeth Tower. That's like sticking an electric clock dial to the top of the Empire State Building and insisting it is the tallest clock tower in the World... I think it's better to say it has the largest and highest clock face on a building in the world which is a slightly different thing.
Totally agree
Whoever created and figured out this clock's mechanisms is a genius.
Thanks for thia video, it really made my day!
I was thinking the exact same thing. How do the people that invented these sorts of things even begin to come up with this stuff. How did we go from banging two rocks together to make fire to watching complex animations on complex devices🤔
Thanks Nitzney
@@JaredOwen Hey Jared, how do you figure out all these engineering feats. Do you actually go out there and find the schismatics and designs ? All the same this is so amazing 🤔
@@LordofRacoons By the curiosity and intelligence of Homo Sapiens.
For someone who played Assassins' Creed Syndicate and disappointed that I can't get inside the tower. This is amazing.
In watch dogs legion there's is a mission where you can get into the tower (but it's slightly futuristic)
Still would've been cool tho
@@hefywefy5331 Futuristic is when game devs end up with no good ideas so they make it futuristic so it can engage 5 year olds.
I watched a few of those videos when I was learning about the tower. I was disappointed too!
You should play Watch Dogs Legion - there's a sort of mission where you control the jumper within the tower. The WDL version of Big Ben is far more complicated than the real thing - i was actually a bit underwhelmed by this at first until Jared went into more detail of how it works.
You can go in and climb to the top. You just need to ask your MP
The tower was recently named about ten years ago. The bell, is named "Big Ben." Big Ben is a cousin to "The Liberty Bell." Both bells were cast in the same foundry. The original "The Liberty Bell" went down at sea. Another was cast that made it's way to the United States.
Specifically named Elizabeth Tower 10 years ago, prior to that it was St Stephens Tower
I've lived in London all my life, and I never knew all those things. This video was fascinating - thank you.
There's a reason for over two million subscribers. Each video is meticulously made and incredibly interesting. One of TH-cam's great channels.
I’ve got an explanation for anyone wondering about the strike train:
Basically, there’s a wheel on the front of the movement with gaps cut into it. The space between the gaps increases with each passing hour. An arm with a flat piece of metal on the end rides along the top of that wheel, and for most of each hour, it is sitting inside of one of those gaps in the wheel. This holds the striking train in place, preventing it from striking until the top of the hour. At the top of the hour, after the chimes have played, that arm gets lifted out of the gap that it’s in, freeing that timing wheel (and therefore the whole striking train), which then begins to strike Big Ben. After the correct number of strikes have happened, the next gap arrives, and the arm falls back into the timing wheel, locking it in place once again, and stopping the strike train. I hope this helps!
By the way, it’s also worth noting that a similar system is used for the chiming train as well, but there’s only four gaps in the timing wheel rather than 12.
Also worth mentioning that at 15 minutes past only the first four notes chime, then at 30 minutes the first eight, at 45 minutes twelve chimes and before the hour we hear the full 16 notes.
th-cam.com/video/CGSzApbCp4w/w-d-xo.html
During the restoration of big Ben workers found a time capsule from the 50s at the very top, the workers in the 50s found a different time capsule from when it was built they removed it and put there own up there. So now a tradition that modern workers will continue
Beautifully explained and illustrated. When I visited London, I was across the street from this great clock at noon. I can't convey the experience of being fully enveloped in such a rich and resonant live sounds.
4:40 that chime is the quarter to the hour chime. the full westminster chime has 16 notes
I remember when i went to the London Eye. The view was really great and you get to see the river and go very high. The capsule thingies has alot of glass in them and didn’t shake. Also the doors to the capsule were automatic and people have to check what you have and then you get through.
I must have 300 antique clocks, and i still like seeing anything clock related. Ok im impressed, you even nailed the types of trains for the movement, and you explained them quite well.
I've lived in London, and often walked past the Clock Tower - any time of day, and in any kind of weather, it is such a true British icon!
I agree! Love this tower
And a world icon! I'm in America, and love Big Ben!
Perhaps I missed it, but I was wondering what mechanism is used to strike the correct hour (1 - 12). I, of course saw the mechanism to strike Big Ben, but didn't notice the number of strikes. Interesting video and nice presentation.
I'm guessing, just like the quarter bell, a similar arrangement of teeth in increasing order (1, 1.2, 1.2.3, ...) Every hour interval must have been there for striking big ben.. again it's my guess
I don't think that you missed it - the feature explanation which is missing is how the striking chain is controlled to only strike the correct number of times for the hour.
It appears from a photo that I found of reconstruction work that there is a disk which turns once every 12 hours and has notches in it spaced so as to allow the ringing mechanism to turn the correct number of rings until a pawl falls into a notch (radial slot) on the disk, stopping ringing until the pawl is lifted to initiate the next ringing event.
11:55 "I'm here, at Big Ben, the iconic clock tower of London, and today, I'm going to be helping wind up.. that big weight behind me."
How they built this and made it so precise without modern construction equipment and electricity is astounding!
dude, the pendulum is preciso to the penny, this was made by aliens
The chiming system works just like wind-up music box - sensible, but amusing.
I am absolutely blown away, Jared. Oh my goodness!!! Can't believe I haven't heard of your videos prior to today. Thank you so much for all of the detail and for the endless hours of work that these videos must take. This is remarkable. I've learned so much here. Learned that this clock is far, FAR more complicated than I could have ever imagined. Keep up the amazing work, you absolute legend! :)
Went on a trip to London for the first time in my life last week. I was really impressed by this clocktower somehow, online pictures don't make it justice at all. The gold accents around the dials are simply gorgeous when the sun shines over Westminster.
Edit: they're either already done with renovation or they cut a couple of objectives from the list and finished earlier than initially intended. The tower was fully unwrapped and operational around 7 days ago
Oh neat! Thanks for sharing, yeah I knew the scaffolding was almost all taken down
Thanks for the news.
actually, it is a lot less impressive and much smaller in person
@@DrWhom It's indeed very small, but the colors and accents looked fantastic to me
Was it chiming and striking, as well?
I'd seen so much about the Great Clock. But then I saw your What's Inside the Titanic, and saw you'd done one on the clock, so came - expecting a great video, though not necessarily to learn anything new. I wasn't disappointed - it _is_ a great video, and I did learn a few new things - how the pendulum movement translates, the existence of the lever room, and the plans to install a lift (elevator), for example.
A few points:
• The bell (and there's some controversy over whether even that - or any part - is actually called Ben) is actually the second one; the first one (made in the north of England) was tested in the square below, using bigger and bigger hammers, until unfortunately they broke it beyond repair; the original makers didn't want to make another, so a local company took the metal and recast it. And it was raised to the belfry by hand! They must have been quite shattered (sorry!) when they cracked that one, but as you show it was rescuable. (The crack is monitored from time to time to make sure it isn't growing!)
• The chiming and striking mechanisms are - though magnificent in their size, and mechanical ingenuity - not _that_ different from what you'd find in any chiming clock; the main difference (other than the size) is the fly fans that regulate their speed. It was one of those that broke after many decades of operation, causing the chiming mechanism to run away with itself, and the drum that held the weight cable to leave its mountings, and generally do a lot of damage to the mechanism, including cracking the frame in several places. Fortunately all was repairable!
• The refurbishment of the Elizabeth tower was somewhat delayed by CoViD, though has been completed, and all is well again (and, as you say, the original bright colours). The tower does actually have a slight lean - about nine inches at the clock level, which is insignificant given the size - though it is monitored, and measures are in place (basically, to pump grout under one side) should they be needed.
• The renaming to "the Elizabeth tower" was a gift from parliament on the occasion of one of her jubilees (significant number of years as queen).
I live in Iowa and we have a bell tower here, too. In Jefferson, it’s called the Mahaney (ma-hay-nee) Bell Tower. It was completed in 1966. We also have the quarter bells chimes (Westminster) and hourly notifications. The difference is ours is shorter and only three sides, plus NO clock faces, but we DO have 47 live carillon bells. We have songs played 3 times a day at 5 past the hour.
"When the tower was first built, it was known as the Clock Tower"
Hmm yes, a clock tower called Clock Tower...the floor here is made out of floor
The Elizabeth Tower will never be as supreme as our Juche Tower. The symbol of my grandpa's ideology. Built for his 70th birthday, and has 25,550 blocks which symbolizes each day of his life up until 1982 (though he passed in 1994; 365 × 70 = 25,550). It's the best birthday gift one can receive, and provides amazing views of Pyongyang
Just a small inaccuracy: “Big Ben” isn’t the large bell’s official name. It is officially called the (very pretentious) “Great Bell”, but it is nicknamed Big Ben.
It's the name absolutely everyone has called it for well over a century, so the distinction is irrelevant at this stage.
@@Zveebo it’s not irrelevant God has original name and nick name the original name should never become irrelevant … give thanks too cactus for the information because I never knew that and I rather be different and call it the original name because I love originality thanks cactus 🌵
Thanks for letting me know something i didn't know.
How is it pretentious? Its a massive bell. Hence "great". Like The Great War, aka WWI.
@@Zveebo Now, now, children, let's not bicker. If the term "inaccuracy" makes you uncomfortable, just replace it with "strictly speaking", which sounds more agreeable.
I chose this video in a chance. I did not realize how much I would love this! It told me the full story without making me feel dumb. The animations were perfect to explain each step.
Absolutely fascinating. I've lived in London on and off, and I love the sound of Big Ben but had no idea about the internal workings. Very well presented.
Mechanical stuff like this will always be infinitely more impressive than some circuit boards
maybe visually, but if you understand the borderline witchcraft that goes on in electronics, then you will be amazed by how much more impressive a simple calculator is.
Dear Jared, your videos are amazing and helping to understand how things work. Thank you.
9:45 is my favorite part when the video turns on the Westminster chimes
Jared Owen, Thanks for helping us understand things we so much take for granted. Best of luck in the future, I will never stop watching your videos. Thanks again.
you know its a good day when jared owen uploads
Thanks!
At 2:24
Jared : Big Ben survived two world wars.
Putin : Not another anymore
recently visited london and saw the renovated big ben and it looks absolutely incredible
Awesome!
Great video!
At first I thought that he was saying that the whole WM Chimes would play every 15 minutes. Then I noticed he said PART of them.
It's impressive how something so massive can be drastically effected just by resting something as small and light as a penny on such a heavy pendulum.
The length of the pendulum, from the pivot to the center of gravity (CG), controls the period. Changing the position of the CG, by adding or deleting a penny, changes the length of the pendulum, and thus the period changes. Temperature will also change the length and thus the period.
Man, this is a cool video
9:40
*gets fnaf 4 flashbacks*
R.I.P Queen Elizabeth ll We all miss you
RIP Queen Elizabeth 🪦
The clock showed at 6:00 isn't exactly 'pendulum clock'. It's just a fancy clock. The one that actually worked on pendulum were those human length clocks.
I know you many already know this.
A small "mantel" clock can also be regulated by a pendulum, although for decades they have generally been electric clocks with a decorative pendulum. A tall "longcase", "all-case", "floor" or "grandfather" clock case is only needed to provide a decent operating duration with a gravity escapement; shorter clocks use springs. There is even a rotary or "torsion" pendulum design for shorter clocks.
I am pretty sure that you made a mistake at 12:24
A heavier pendulum takes longer to swing from side to side. So the clock will run slower with more pennies
----
Ok I found the problem.
They put the pennies on top of the pendulum so the center of gravity goes up. This has the consequences of speeding up the clock.
If the Pennie’s would be placed below the center of gravity the clock would slow down.
No, the period of a (small-oscillations) pendulum depends solely on the length of the pendulum. The analysis in the case of bigger oscillations is harder to do, but I don't recall it depending on the mass of the pendulum either.
🤓
My 4 year old son is fascinated by your videos, he talks about you and all the things he learnt from watching all your videos. He would rather watch this than those other kids action animations. Thank you so much for teaching us
Oh Big Ben.. your chimes creates vibes beyond description..it echoes across the thames.. reverberates in the heart of each Londoners.. forever ..
The bell in the middle is not officially named "Big Ben" but actually "The Great Bell". Big ben is it's nickname.
Great vid! :)
Thank you! I appreciate the feedback too
Calling the biggest Bell Big Ben does however make more sense and it is actually to as that anyway
5:09 Thought some AC/DC was gonna break out...
this made me love engineering even more, it’s fascinating, the legendary clock’s design is undoubtedly out of this world in-spite of its historical past. glad to have a fresh renovated icon this year at last!
Hi Jared, I’m writing in my son’s name he is a 4 years old boy and loves your videos. Especially the Big Ben and statue of liberty.
He is sending you a big hug and a big thank you for you and your work.
His name is Francisco.
All the best!!
Mr. Owen, your explanations and 3D visualizations are always most excellent and I always look forward to seeing them. Educational, and a feast for the eyes! I appreciate your work as I'm a 3D artist by profession. Cheers to your beautiful work!
Thanks John!
This video is a wonderful illustration of how this tower and clock work. I can't imagine the amount of time that went into gathering data and creating all the 3D modeling. Thank you for posting this.
You're welcome! Thanks for watching
Great video - not too detailed; not too superficial.
Jared, Very impressive video!, i'm a Londoner and love seeing the tower, and i hope you get to see it too if you have not already done so, the tower features in every new years eve fireworks display and the chimes of Big Ben see in the new year , its so nice seeing the tower without scaffolding and looking new after so may years of renovation.
you should make an animation on how VHS tape players work, because those are fascinating
VHS or Beta, or even the audio variant of Beta - the mechanism is similar.
"mom i cant sleep because of the bells every 15 minutes"
I love that chime but it sound like the half chime 🔔🔔🔔🔔
Since i was 3 years old i never noticed big ben's renovation
but now i learnt this and happily its fixed again
This clock tower is the very embodiment of "They just don't make 'em like they used to!" - I can guarantee that by the time that fancy modern "Largest Clock Tower" breaks down, Big Ben will still be ringing every hour on the hour. As long as someone goes up there with a few pennies to wind up the weights, that thing will keep working.
Once again an amazing animation an explanation of a complex mechinism! Very cool stuff. I laughed at the fact they used pennies to change the weight of the penjulim if weather changes XD Looking forward to your next one man! Keep it up! :D
Not only do they use pennies but, as I recall, these are old pennies predating decimalisation in 1971 when the currency changed completely. A modern penny is very much smaller than the old ones.
I'm not gonna lie, this is some of the best music I've heard in a Jared Owen video. Bravo!
The surprise for me - or at least the feature which is not quite what I would expected - is that there is only a single shaft to each clock face, rather the separate shafts for the minute and hour hands. This is practical, but it does mean that each face needs its own 12:1 reduction gear set, which is not mentioned in the video.
I gotta say, it’s actually a really smart, yet simple way to tell everyone around what time it is
The only other thing I would have liked to know is how the mechanism decides how many times big ben should be hit; how that gear train is turned exactly the right amount as it would differ each hour.
Unless you are James Bond, who can have the chimes changed to send a secret signal.

I thought I missed that bit, too
Look up how a "countwheel" works, that's the mechanism that decides how many times it will chime on the hour.
Yeah I feel like there was a little bit of info missing from this vid, but I guess I can fine that in another vid
That would have pushed it over the 15 minute mark and messed up the algorithm!
I appreciate the awareness of the need to point out where England and London are on a map.
I have live in England since 1990 and visited our capitol on multiple occasions,visiting most of London's great buildings and this is the first I knew of this.Thank you so much forbposting this!
Capital* lived* posting*
You should do a video on the Antikythera mechanism! It's the oldest device with complex gears that we know of.
I love your videos Jared, I wish you had your own Netflix special. The amount of detail you give in each of your videos is amazing. Please keep up the great work. I learn something new every video of yours I watch
Thank you Alex!
No Netflix please. Choose another platform.
@@JaredOwen Absolutely! Big fan
jared owen is the only person that has explained complex thongs very simply and i love that
Notice the blue "See Inside" button in Scratch? It loads the Scratch Project Editor, which you can Change the Sprites/Backgrounds (in Paint Editor), Sounds (in Sound Editor) and Coding (in Script Editor).
Iconic tower! Great video!
This man teaches us more in 14 minutes that school can in 8 hours
Wow! What a fantastic video. I have just subscribed. Expertly presented and the questions I had in my mind while it was going, were all answered. This presentation is as clean and detailed as you can get. Well done mate!
Great tower and an awesome animation ! It truly amazes me how it was possible to build such structures in the 1850s as most probably there were no electric- or hydraulic machines available, and everything had to be done by hand and by muscle power. Truly astounding !
They had steam power.
Am amazed with very tiny details you presents in your animation and videos.
Thanks as I have got to learn more from your videos 🙇
Nice videos. You should do one about what's inside Tower Bridge, London.
As an Englishman I find it quite amazing that at the start of the video you had to point out where London was for your American subscribers
Correct😀 Kids need to know there geography
Really? Why? London's location is of little importance to anyone who is not actually travelling there. Do you expect everyone in the world to know the location within the country of the capital of every country in the world?
It's just great how you make things understandable. Thank you.
I am such a huge fan of Big Ben and now I fully understand how it works thank you for making this video
Eu amo esse canal! O melhor que existe em matéria explicar como as coisas funcionam! Parabéns.
This is a fabulous video. In the UK we grew up to the sound of Big Ben’s chimes which btw were used for a 24hr speaking clock that people could call to adjust timepieces, it was also used for News channel intro’s etc. Living in London you get used to its unique sound being part of the soundscape.
GOOD JOB, 00OWEN. YOU DID YOUR HOMEWORK. THE U.K. IS PROUD AT YOU.
10:17 i somewhat knew on one of the bells it had 2 hammers
Funny big grandfather clock
Funny big grandmother clock
Thanks for creating this video, I really enjoyed it. You have no idea how happy it made me! I´m going to re watch it a few more times for sure.
