The Beautiful Engineering behind the Arch Bridges! 

I hope you enjoyed the Arch bridge video. Lesics is currently fighting for survival - www.patreon.com/Lesics . Your support matters a lot to me and my team. You will also get access to exclusive engineering videos. Thanks Sabin

I like how Vande Bharat Express is running over Chenab Bridge 😅 hope to see that soon 🤞🏼🤓

Some of us would appreciate greatly if conversions to SI were included. 7 inches? 160 feet? I had to Google it and it is quite a pain in the arse. Anyway, great video as always.

I love the circular vs parabolic demonstration yall did at 1:32 it made it really puts to perspective what a shape change would do keep up the good work

A video covering the chenab bridge, India would be highly appreciated. Great work!

This is why Lesics is a FEATURE Channel on my RU-vid channel. Great art work Lesics, more of this. 👍

The International System of Units uses metric. So I think you should add METRIC units on your phyisics and engineering videos to be even more pro. BTW superb video, LOVE IT !

i went to school near this bridge and you answered a lot of questions i have had for twenty years. Thank you!

I love how this channel gets so into depth!!

The harbour bridge was built by Dorman Long - Middlesbrough UK. My 98 year old Grandfather became the head engineer for this firm and worked with the engineers of the harbour bridge in the fourties and fifties.

Can you also add metric measurements in the next video? Thank you for your work

Suggestion @Lesics, can you put also metric system in your videos. That's easier for the 90% of the world population to understand :) Thanks

A video covering the Howrah Bridge of West Bengal, India would be highly appreciated. A bridge that stood the test of time! Great work!

Such lucid and simple explanation for complex engineering marvels! Amazing works, Mr. Sabin🎉!

Such a awesome explanation ❤ big salute for your huge effort....

I like the way you give details about things. Thank you Lesics

You made it so easy for lay audience to understand something so technical. Excellent work, keep it up.

Awesome! Goes nicely with discussion of parabolic shapes in RealEngineering channel's video on the Sagrada Familia.

Those videos are very satisfying to watch. Very well explained. Nice work, good job

FANTASTIC VIDEO , YOU MAKE EVERY WITH DETAILED ANALYSIS AND MAKES EVERYONE UNDERSTAND THE ENGG. CONCEPTS IN SIMPLE WAY

I love the quality and effort to put the every Detailing in the video love you never end this. You are awesome. Very very very very very much love and respect for you and your team.

We need more of these, thanks for the video.

This is awesome. And just like at 6:20 it's amazing what is learned over time when population and technology expands.

Waooooo what a marvelous engineering behind this parabolic arc bridge. Thank for making it easier to understand it's construction 🤗🤗🤗

i remember watching the build of this in school and one of the things i found most interesting is they learnt what the benz was from digging in the pillars

i have a microbiology tomorrow and here I am learning about bridges!! , nice !

Honestly, Your channel makes structural engineering more & more interesting I can't stop myself to continously watching your knowledgable videos.

I'm happy that I'm watching this great animated explanation Thankyou!

Thank you for this detail analysis

The effort you put in explaining the science is as meticulous as the real construction itself. I was stunned and forgot to sit straight

As always, an incredible video!

Wow!!!! Amazing video and amazing channel. Excellent explanation and cool animation. Keep going.

Beautifully Explained Thanks for sharing such informative videos, Kudos To Your Work ✨💥

Tnx Bez of this video I have great talk with my dad about engineering

Explained in a perfect way.👍👍

One of the best videos on Engineering 👍👍👍👍

Awesome video. Explains much better than some teachers

Wonderful Presentation. ❤

Thanks for sharing 👍❤️!

This man never disappoint us

Masterpiece of engineering

The harbour bridge isn’t a parabola - it’s a catenary curve inverted (a hyperbolic curve). A parabola and hyperbola are significantly different.

Wow it amazing technical explanation thank you

I'm not a engineer student but I learn something new from your video. Thanks SIR💙

That's amazing

For anyone that doesn't live in Australia, it's just the sydney harbour bridge.

Awesome explanation, thanks

Fascinating!! 👏🏻

Awesome video! Thank you!

Man, this channel taught me a lot

one of the best construction animated video ever seen

This is right up my street. Thanks

Amazing explanation thanks

Thx. I learned several new things (I took several years of Structures at Uni level/Architecture). As to the SHB, I've been over it a few dozen times - -but still knew very little about the process, or thought behind it. Special mention: your video is well-pitched to noobs (excuse the expression, but it so fits!) - and I really liked that you put questions to the viewer. Engaging the viewer keeps attention and empowers. All most excellent. Fab CGI, too!

woww... this is very cool, the explanation in the video is very clear

I had a confusion at the beginning when you said the parabolic arc was the strongest structure, precisely because it should be catenary. Thanks for clearing it up.

It's super Impressive!!

which software did you use to create this video?

Amazing video, thank you. Please tell why a parabolic shape is used instead of a catenary?

Very knowledgeable video sir 👍👍

awesome explanation

It would be good to have the metric system used also being Australia use this system

Great work THank you

So nicely explained

Thanks for sharing

USA built the America’s bridge over the south entrance of the Panama Canal…… It is beautiful and huge! They used the parabolic design. Regards from Panama 🇵🇦!!!

I don't know why I can't help but love your videos...

Keep making these videos they are awesome

These videos are so awesome

The Sydney harbour bridge didn’t have 4 railway tracks. It had two railway and two tram tracks. When they shut down the tram system they converted the tram tracks to extra lanes.

Thanks , I agree with this bridges.

The animation is awesome!

catenary curves and parabolas have slightly different equations, and it's catenary that are the primary curves used in self supporting structures ;) They're very similar in shape and _sometimes_ are interchangeable, but they are two different things.

I, as a man, feel proud. Yes, we built this world and I am proud of it.

Amazing content!

It would be fascinating to see the hinges marked off in degrees or another way so that the keen observer could appreciate the science involved.

This is amazing.

Excellent video

Super amazing. Pls what software do you guys use in creating this video.

this was an extremely advanced and impressive feat for Australia back in 1932. Australia has always been a bit behind the rest of the developed world(not anymore) so its amazing that we pulled this off so early.

I have a few douts; when you talk about the parable beeing the most efficient way to transmit load, you refer to the catenary? Or is the parabola so similar to the catenary that the difference between the two is minimal? Is the catenary the most efficient form of load transmission, if not why parábola it's better than catenari? Thanks a lot for the video, its amazing. love your work.

Great animation and interested subjects

Thanks lot, much interesting video, Good luck to all!)

Thanks I am waiting to another amazing videos .

Thank you 🙏

wow this video is super eductaional and amazing video that fulfilled my knowledge. would you mind posting more about structural reviews for stadiums and civil infrastructures ? thank you

Impressive engineering, I hope you make a video about the CCLEX or the Cebu-Cordova Link Expressway here in the Philippines. Want to watch it sooner ❤

nice as always

Very informative

Wow so amazing ❤️

If I had watch this channel when I was younger. I would have definitely studied architecture at the university.

Omg what an explanation!!!!😍♥️

I like your references of Indian technologies

Nice video. Thank you

Hello. This video is best. In which program do it? 3dmax or blender?

Attention to detail is amazing. Amazing video. Also I have a video idea, pls consider it- engineering marvel of Brooklyn bridge/kibble balance/inertial navigation system. thankyou

Thank you!

This is why, the strength of materials is very important to learn.

Thank you so much as always. I've e Q: Why didn't we use Trus bridge. As I think those are more robust. Please reply.

Amazing video
