Empire State Building | All the Secrets of the Engineering Wonder 

Hello everyone, I hope you liked the Empires state building video. Please support Lesics on Patreon - www.patreon.com/Lesics

My grandfather was a postman in this building around wartime and told us he made more money in tips from grateful businesses at Christmas time than the postal salary.

There's no way a Channel of this quality can go down. Immediate member. Really hope you can recover 🤞🏻🍀 RU-vid needs to do whatever is in their power to promote free amazing education instead of dumb people fighting over nothing and making millions out of it.

Great video. One correction - the building getting narrower towards the top was not an aesthetic choice, it was a legal requirement. After the Equitable Building was built downtown, all skyscrapers had to have setbacks if they wanted to go higher. This was done so that the buildings would not block the sunlight from hitting the streets. More info here - en.wikipedia.org/wiki/1916_Zoning_Resolution

"does this resemble something?" : my creative mind telling me something else

Your channel is extremely under rated!! I don't understand why people don't want to learn science even when it's represented as best as possible.

It was built in 13 months around 90 years ago, no computer aided design, none of the technology we have today. It also was built ahead of schedule and under budget. Compare that to the 6 years with all our modern technology it took to build the new Wembley stadium, which ended up way over schedule and much over budget. How is this possible?

Here come the 9-11 conspiracy theories

Now please do the Twin Towers!

Fun fact: zero feminists were used during the construction of this structure

It sad that this thing was build during the Great Depression and we can’t get our act together now.

Dude it's really a good civil informative video . And hats off for your effort on data collection ☺️☺️☺️

73 elevators. Well the elevator repair and maintenance team got job security hahaha

I worked for this building for years. Never once was sick of hearing the history and its still my favorite building

I'm sorry to hear about your financial problems--you make good videos! You don't need all of the fancy animation; simple graphics and good explanations would be fine!

It's a shame you didn't mention the bricks used in the foundation. They were called Accrington Nori's and they still are the strongest brick in the world. They come from Accrington in Lancashire England. There name comes from Iron being backwards on the mould by accident. They are so strong because the amount of Iron in the clay.

I really don’t want this channel to shutdown; I would much rather have this content promoted.

A building built almost 100 years ago stood up the impact of a plane, but a 110 story monster with far more advanced engineering collapsed like a house of cards in 2001? Seems legit. Right?

That plane also wasn’t a Boeing 767 headed from Boston to L.A on a full tank of gas…

That plane was much smaller and lower on fuel.

Great work! I love the videos about bridges, buildings, and dams. The explanations of problem solving and construction phasing are top notch. You make me a better civil engineer.

They were not steelworkers: steelworkers work in the plants that MAKE the steel. The men who erect it are IRONWORKERS

Nah it stood strong because jet fuel can’t melt steel beams

Unbelievable that this was done in 13 months even by today’s standards that would be fast incredibly fast

You should compare this building to the Twin Towers which went down on 911. They were built quiet differently.

already the fact that they tell this masterpiece was constructed in 13 months confirm it's whole story is a blatant lie.

The quality of all things American built from the 1880s through the 1930s is amazing. From a pair of Levi's to pocket watches to cars to skyscrapers.

0:07 Not enough bombs and de-atomizing beams.

Thank you for your great science content. I learn a lot through your channel

What about World Trade Center 😂

Iron is the god of construction, hats off for the iron metal 💪🎩🎩

And the Twin Towers collapse unfortunately.

You have one correction to make. Ironworkers assembled building by driving hot rivets. High strength bolts weren't used for several more decades.

0:00 - 0:33 wait, i thought jet fuel could melt steal beams.

crazy how in 8 years this building will be 100 years old

Big difference between a slow moving bomber and an airliner full of fuel traveling 500 mph

Notice how it's a Volvo that got hit in the last seconds of the video and go no damage. This channel is really accurate on everything

Good luck building a cow shed in America in under 13 years now.

The amazing thing is the lack of comments with the obvious observation that the World Trade Centers could not have fallen at free-fall speed because of an airplane crash, given their improved structural rigidity over the ESB

The best channel award goes to Lesics from me ❤️

It's been said that the stepped design of the buildings is due to air rights regulations in New York city but I saw no mention of that in this video and instead it would seem that this video suggests it was a purely aesthetic choice. Please explain

Im a construction worker and a lifelong new Yorker and this building captures my imagination like no other and even with all my structural know-how it still absolutely boggles my mind this masterpiece was built in the middle of the great depression in 13 months...I mean really even with the superior technology of today it takes us much longer to build though I know this could be accomplished today .. regardless of when it'd still amaze me I mean what we can accomplish and create really is something absolutely worthy of awe...man I'm not afraid of heights but it'd take me a long while to be able to do what these guys did and even with much practice I don't know if I could ever be like them walking 1000 feet up as if they were on the sidewalk...im a major architecture buff and I gotta say overall this building is probably my all time favorite and it never ever gets old peering out a window at it or walking into the lobby..it truly is a masterpiece

This is what I'm waiting for lesics, congratulations on your struggle

Haha no one with a bit of construction understanding expects the building to collapse. Not by the impact of some flimsy alloy against solid steal beams. Also never in history a steel constructed building has collapsed because of fire apart from a 1 day even where 3 steel buildings collapsed "due to the fire". Coincidentally right?

I knew a guy who redid the HVAC in the building. He said there were still burn marks and small aircraft parts behind the finishes.

5 workers died building this. 0 died on the Chrysler building

Very Good Explanation with Clear representation

Mrs Christina the bitcoin trader is legit and her method works like magic I keep on earning every single week with her new strategy

where were the sky boys on 9/11

Would be interesting to know if the building was bent after the aircraft crash, even if only a few millimetres or so.

Ironworkers!! Not steel workers😁

If this channel's founder doesn't get any rewards or awards. I'm gonna lose faith in humanity

8:09 well I guess the other two buildings in the area weren’t so lucky

Let us all write to RU-vid CEO Neal Mohan, and Alphabet CEO Sundar Pichai, and Education Departments to provide some financial support to this channel. We should also help as much as we can. There are a few excellent educational channels on RU-vid. Lots of strange people talking trash, making fake news and political statements have raised millions. And here is a channel that helps us understand technology--about computers, internet, electronic devices, AI, current and future technologies, etc. We need to support it.

2 minor nitpicks: You showed the 101st floor as the 102nd. The 102nd is the space with the open-air wrap-around "porch." Secondly, the 1945 crash did damage a floor girder enough to require replacement, but no vertical columns needed replacement.

As I remember back in the 70s, they had a glass showcase with a brick in it, and if I remember right it said they had ordered either 10 million or 100 million bricks for the building and had ONE brick left over! Those terra cotta blocks used in the floors were commonly used back then in partition walls and elsewhere, they were why the gothic styled building at 90 West Street which had raging fires after 9/11/01 survived. They still use these blocks to-day in home contruction in Romania, Slovakia, Hungary, and I imagine elsewhere in Europe. I saw google street views of a new house under construction in Hungary, it used those same terra cotta blocks which were then faced with stucco, while the roof was made with red terra cotta roofing tiles. They are superior to the cheap concrete blocks we use- larger in size and having multiple cavities in them, they have more insulation value than concrete blocks, and since they were clay that was hardened and vitrified by FIRE, they stand up to a fire whereas concrete blocks crack and crumble because concrete is made into a powder by grinding up and burning limestone, adding water and sand to that chemically cures it into a hard form but it's not vitrified like terra cotta

Wow, so they did 9/11 half a century before it became main stream. They were ahead of their time 👏

One of the best channel I have ever seen. Simple language with attractive graphics. Any one can understood easily about difficult things of engineering. Its very sad to hear the financial problem. Insha Allah, your problem will be solved soon. Hope for the best.

It wasnt a speeding bomber-it was a lost bomber probably going minimum speeds.

Thanks allot for the video after long time i was waiting

I really love your channel, I hope people stop watching stupid tikto videos, and spend their time learning from your channel! Love you lesics team! 💪💯🔥 Stay strong

Also please make a animated vedios on related electronics telecommunication engineering

The mentioned race to the world's tallest building took place between the Chrysler Building and 40 Wallstreet. Not the Empire State Building.

What an astonishing way to show the financial crisis. Wishing for the best to you- Lessics/Learn Engineering.💜

Such quality content, idk my RU-vid isn't promoting it to more people!

Meanwhile the Twin Towers 💀

ONE year,,, YES,, only took one year to complete a 102, one hundred and 2 stories skyscraper,,, yes,, that was something in the past,, unfortunately today as 2023 and the next future,,, no more such story exist in the united states,, never,, ever.....

Really awesome production quality - the building and the video!

Instead of focusing of the ESB’s construction as was the video’s purpose, people in the comments are focused on 9/11 🤦‍♂️

More than 20 years later and they're still trying to explain why 3 building on fire with minimal damaged just collapsed into their own footprints.

What an amazing and high quality video! Thank you guys so much for posting it. It really made me appreciate the design of the Empire State Building. As for the design, I'll admit that the Chrystler Building looks more like a pencil shape than the Empire, but I get the idea of what the architects were thinking. Both are amazing skyscrapers!

Very interesting, thanks for sharing your knowledge and experience. Congratulations 👍

about this channel, you guys have 6M subscribers and getting a significant revenue from views , I don’t understand what you said in the end of this video asking for patreon fund from viewers !! 🤨

The animations are very illuminating. The pencil comparison for example. But all the othe otherones are so great too.

No diversity hire, just 100% built by real men. 😊

So happy to see a Lesics video!! 👏👏 Hope you keep making your incredibly awesome educational content and live on for many more decades.

The first Steel framed structure, used to build and support a large Factory, was in Shrewsbury Shropshire, England, in the late 18th century. Prior to this, , all buildings had beams of oak, which burned easily.

Nice knowledge 👌

8:24 channel with more than 6.3 million subscribers undergoing financial troubles? how come is it possible?

Remember when two planes took down three buildings

Did you know that the ironworkers were members of the Haudenosuanee Indigenous peoples of Canada.

Please stop using metric measures when featuring American built structures. We do not use metric and not many people here understand the metric system. We use feet and inches. Wheather you like it or not, engineering in this country is still using the American Standard Measure Units and will continue for quite some time.

Thank you team Lesics for continuity ❤

One thing that I noticed on some old film about the construction of the empire state building was how to achieve the required precision that all the steel beams and girders. After all the plates were riveted together, this would leave both ends rough and uneven, the iron workers would run these assembles through a giant milling machine that would shave both ends to a square and determined length. By making these all square and the same over all length, they could easily take them to the building site and put in the main assembly of the building without much drama to get things to line up. The brief moment in the movie clip that had this milling machine, showed it must have been huge. There was one of these Carnegie beams mounted in the machine and the two cutters on either end were both turning. These cutters looked to be about six feet in diameter and the bed of the machine must have been about 50 feet in length. I am curious, is that how big i beams are made, no rivets, all welded. But do they still shave the ends to maintain the length and squared ends?

It helps when there isn't thermite attached to the columns. Like WTC 7. Also known as building 7.

Awesome video!!!

would the empire state building have collapsed if a bigger plane had crashed into it?

The aircrafts that hit the Twin Towers would have done the same minimal damage. The buildings were filled with explosives.

Somebody should tell the American feminists about the "sky boys"....

Wait, an airplane crashed into the empire state building and a building down the street didn't fall at free fall speeds as a result? Weird.

Logistics are the make or break of all constitutions. Time is money!

Should have tried again with a bigger airplane. I wonder if anyone ever thought of that...

It took longer to buid a ditch in my area in 2021 🤣

What about lies of 11/sep/2001 buildings 😏

@5:45 Because there was no union at the time.

31 mins since upload and 3.8k views but only 400 likes. I don't understand why people not hitting the like button in such good content

Future = İlluminati will destroyed Empire State!!!

Over 6 million subscribers, no controversial content (no demonizing), no advertising, why. Seems that you choose to be in financial trouble. I don’t get it.

The secret is not having charged explosives and weakened beams and needing to enter a profitable war

Man if they had build the World trade center like this too they would have not collapsed 😌
