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 🤞🏻🍀 UKposts 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

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

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.

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

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

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.

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

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

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.

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

Now please do the Twin Towers!

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

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

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

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.

Easiest Subscription I’ve put in for. I can’t let this channel die, not after how much I’ve learned from it.

This video answered several of my life long questions pertaining to the Empire State Building. 10.9 thumbs up!

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!

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

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

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!

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

Thank you team Lesics for continuity ❤

Terribly EXCELLENT video! You made me feel so connected to it.

wow, this is super amazing, the best video in the youtube i ve ever seen. thank you for posting this educational one . really love it

The best channel award goes to Lesics from me ❤️

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

Informative and professionally executed. Thank you.

Really awesome production quality - the building and the video!

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

Very Good Explanation with Clear representation

Thank you Lesics for the awesome details and information.

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?

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

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

the only thing i can do to help my fav channel still affloat is by watching all ads no skipping. to donate i dont have money. thanks for all your hardworks lesics team. i learn alot

This is one example of old school engineering provided the best results 👍.

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

Thanks for the story about this incredible building.

I don't think anyone today could do what these workers have done back then. Such perfect engineering. Something not seen anymore. We give our thanks & gratitude to those hard-working Americans.

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

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

I think the stainless steel on the Chrysler building was very carefully chosen when they were looking for one that would stay bright. I heard something about it on one of those educational TV series along time ago. It was probably on the Discovery Channel or a similar one.

Could you make more buildings, bridges n structure videos please, i think how abandon buildings are made would be really cool video to watch too💯

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

Krpp the videos coming. I really enjoy them. Great work

Excellent animation, particularly for some new to Steel Structures.

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?

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

Thank you so much for making the video for free. I will consider supporting you once I start earning. Thanks

This is one of the most amazing channel. Keep it up

Nice knowledge 👌

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

Amo o lesics força o canal vai em frente

Thx for video u answered alot of my questions.

Awesome video!!!

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

Such quality content, idk my UKposts isn't promoting it to more people!

Wow... clearly explained.. 👍

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

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

Seriously 3 months thats huge 🔥🔥🔥🔥🔥

That was incredible!

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

Also please make a animated vedios on related electronics telecommunication engineering

Maravilloso edificio ❤❤❤❤❤😊

I really enjoy watching your videos

Let us all write to UKposts 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 UKposts. 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.

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

Trying to tickle the algorithm, awesome video man!

Amazing spectacular engineering. ✌️

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

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

Great job guys! All was good: animation and the narrative. Really impressive. Thank you! Love ESB. Been there twice. But what I really am missing is twin towers. I've been in the new tower built by their side, but - telling you - without the Twins NYC skyline is not the same. Something will be missing all the way.

To cover the columns, perimeter beams were used, but this small change affects the entire structural calculations unless it is designed overhand.

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

Here come the 9-11 conspiracy theories

Nice illustration ❤

Well explained.

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

Meanwhile the Twin Towers 💀

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

Nice video. People should look up the building that was there before the ESB, it was beautiful.

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.

4:14 “…until 1971 when the World Trade Center overtook the record by 83 meters” Then by 2001 the Empire State Building reclaimed the title of tallest building in New York due to the size of the World Trade Center dropping to 0m

great work lesics

Everyone must have to like his video because he give a great knowledge❤

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

I love your videos. It's very easy to understand

nice work as always

Remember when two planes took down three buildings

What about World Trade Center 😂

Lesics is back yayyy🤩🤩🤩

Can you guys make a video about the varrazano bridge ? There's barely any video about its construction and the challenges imposed for building a bridge of that size

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