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
It's getting ridiculous with the Americans taking over all of the videos we can't even hear about the Sydney Harbour bridge without hearing a Yank who can't pronounce words correctly . And of course you make the video last as long as possible so CZcams will give you money. getting sick to death of hearing your accent I really am. You may love the sound of your own voice but we don't
I like how Vande Bharat Express is running over Chenab Bridge 😅 hope to see that soon 🤞🏼🤓
Vande Bharat is lighter train
I don’t understand. A parabola is not a catenary. I know they are close but a horse is not a cow. Isn’t this unscientific?
@@ProfFeinman We have mentioned this fact, I hope you missed it 03:50
@@Lesics Please make a video on Howrah Bridge(Rabindra Setu) ; Kolkata ; India
@@Lesics 08:50
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
the curve is actually called a catenary, parabola is an approximation.
@@janami-dharmam aka narrow block
@@janami-dharmam I have been taught in my mathematics classes that the curve is a catenary. When you say "parabola is an approximation" do you mean that engineers make that approximation out of need for convenience, or do you mean that mathematically there is a similarity between the two curves❔
@Jack_Callcott_AU, A catenary shaped hanging chain is just a real world illustration for principles that are still applicable to an arched bridge with a parabolic shape.
And since the shapes are slightly different, so will the mathematical functions that model them.

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.
times it by three and add your favorite number divided by two for metres :)
@@Jayesk "add your favorite number"?
Such lucid and simple explanation for complex engineering marvels! Amazing works, Mr. Sabin🎉!
I love how this channel gets so into depth!!
A video covering the chenab bridge, India would be highly appreciated.
Great work!
This is why Lesics is a FEATURE Channel on my CZcams channel. Great art work Lesics, more of this. 👍
i went to school near this bridge and you answered a lot of questions i have had for twenty years. Thank you!
You made it so easy for lay audience to understand something so technical. Excellent work, keep it up.
Such a awesome explanation ❤ big salute for your huge effort....
Awesome! Goes nicely with discussion of parabolic shapes in RealEngineering channel's video on the Sagrada Familia.
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 like the way you give details about things. Thank you Lesics
FANTASTIC VIDEO , YOU MAKE EVERY WITH DETAILED ANALYSIS AND MAKES EVERYONE UNDERSTAND THE ENGG. CONCEPTS IN SIMPLE WAY
Those videos are very satisfying to watch. Very well explained. Nice work, good job
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
Suggestion @Lesics, can you put also metric system in your videos. That's easier for the 90% of the world population to understand :) Thanks
You're very right 👍
Yah, we also have moved to metric units :)
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 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.
Can you also add metric measurements in the next video? Thank you for your work
The effort you put in explaining the science is as meticulous as the real construction itself. I was stunned and forgot to sit straight
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.
It’s a brilliant bit of Engineering Construction 🇬🇧
I'm happy that I'm watching this great animated explanation
Thankyou!
We need more of these, thanks for the video.
A video covering the Howrah Bridge of West Bengal, India would be highly appreciated.
A bridge that stood the test of time!
Great work!
Honestly, Your channel makes structural engineering more & more interesting
I can't stop myself to continously watching your knowledgable videos.
Beautifully Explained Thanks for sharing such informative videos, Kudos To Your Work ✨💥
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!
Thank you for this detail analysis
Tnx Bez of this video I have great talk with my dad about engineering
As always, an incredible video!
Wow!!!! Amazing video and amazing channel. Excellent explanation and cool animation. Keep going.
Awesome video. Explains much better than some teachers
I'm not a engineer student but I learn something new from your video. Thanks SIR💙
Explained in a perfect way.👍👍
One of the best videos on Engineering 👍👍👍👍
This man never disappoint us
one of the best construction animated video ever seen
Man, this channel taught me a lot
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.
woww... this is very cool, the explanation in the video is very clear
Awesome explanation, thanks
Thanks for sharing 👍❤️!
I don't know why I can't help but love your videos...
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 ❤
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.
Wonderful Presentation. ❤
This is right up my street. Thanks
Fascinating!! 👏🏻
Very knowledgeable video sir 👍👍
Keep making these videos they are awesome
Awesome video! Thank you!
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
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
Amazing explanation thanks
i have a microbiology tomorrow and here I am learning about bridges!! , nice !
sambil minum kopi pagi nonton tayangan yg berdaging emang asiikk....mksh ya atas kontennya...bermanfaat banget
Thanks , I agree with this bridges.
Wow it amazing technical explanation thank you
Thanks lot, much interesting video, Good luck to all!)
It's super Impressive!!
Omg what an explanation!!!!😍♥️
Amazing content!
Thanks
I am waiting to another amazing videos .
So nicely explained
This is why, the strength of materials is very important to learn.
The animation is awesome!
I like your references of Indian technologies
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 🇵🇦!!!
My favorite supporting structure is the regular arch (the one the romans and etruscans used)
For anyone that doesn't live in Australia, it's just the sydney harbour bridge.
And it doesn't have 4 train lines; there's only 2.
@Gnuthad It was made clear that two train line were converted to road in 1958.
@@jackchapo2011 I seem to have missed that. Can you provide the time code so I can go back and listen again?
awesome explanation
Great animation and interested subjects
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.
Yes but they did put locomotives on them and as per the original plans they had always intended for the tram tracks to be turned into railway tracks when the demand was there, that just didn't happen because by 1958 cars were "king"
were replaced by roadways as per video.
These videos are so awesome
Bro your are very informational i would like to see some videos for nanotech and it's working
This is amazing.
The harbour bridge isn’t a parabola - it’s a catenary curve inverted (a hyperbolic curve).
A parabola and hyperbola are significantly different.
Yep normally I use a cosh function this, this video is full of wrong information
Jip! Cables hang in a hyperbolic curve.
@@markoj3512nahh bro thins everything is wrong💀💀💀😎😎
It would be good to have the metric system used also being Australia use this system
If I had watch this channel when I was younger. I would have definitely studied architecture at the university.
Love these videos keep it going
hey Lesics please, I request you please make a video on the Chenab bridge. Please
Thanks for sharing
Great work THank you
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.
It doesn't change by much, if the top is only 7 inches different across the year, I can imagine that those hinges move by less than a single degree.
I do not think you can make out visually.
nice as always
Nice video. Thank you
What an explanation!
Excellent video
You can also make a video on the beautiful engeenering behind 'Howrah bridge' (kolkata)
*Not having a single nut or bolts in this bridge and it's still young from past 80 yrs.
loved your videos
That's amazing
Wow so amazing ❤️
Thank you!
Beautiful Sir 🤗
Once I played a bridge building game and man I know how tough is to get the right structure
Thank you 🙏
Amazing video, thank you. Please tell why a parabolic shape is used instead of a catenary?
