please never stop this is amazing

Good video, but I feel like i would have better understood the mechanics of the bridge if i saw some pedestrians getting severely injured when it opened.

Wow. Animation and video quality has significantly improved from last video! Kudos.

This is the first time i saw a hydraulic motor mechanism. Fascinating

Just Sabin casually tip-toeing away from the bridge he just destroyed 😂

Excellent animation and I am so happy you got a sponsor from solidworks.

in a world of endless AI useless videos this is the only good learning channel

Awesome video, as always! Maybe it's worth mentioning that the bridge's mechanism initially used to be powered by steam engines. You can still marvel over these beauties in the bridge museum located in the southern part of the bridge. Now that awesome and complex steam operated mechanism would be worth of it's own video (hint, hint)

Thank you! This video really helped us with building a model of the Tower Bridge.

Very nice video. I love how you explain genius things with simple terms and visuals

I'm grateful for your latest video which is just as well made as the previous ones. This time as a local to the subject matter, I am able to contribute a couple of things. I was rather hoping when you admitted that you had seriously oversimplified the engine room assemblage, that you were about to mention the carefully maintained but redundant steam engines. But perhaps they wouldn't fit with the bright primary coloured visual version of this old marvel. The other aside I'd like to tell the viewers about is to do with something which again you came close to addressing but in fact didn't. Thank you for the heretofore unknown to me superlative pivot points design. You always come up with several of these "Now I didn't know that and I didn't know that I'd be fascinated by that either" gems of engineering greatness. Alas you mentioned the over rotation downwards, as it were, but not in the other, upwards direction. This brings me to my second point: In one of those English exceptions and eccentricities, the roaddeck bascules are only ever raised to fully vertical when the monarch passes through. The last time this happened was during the Diamond Jubilee celebrations for the late Queen when she and the Duke of Edinburgh braved the driving rain being rowed down the Thames on the new version of the seventeenth century Royal Barge.

Amazing visuals and animations. Love the Alfa Romeo 4C waiting at the gates. You've got a new sub!

BEAUTIFUL

Exceptional video as always!

The Trunnion Bearings are truly impressive

I love these kinda videos extremely informative!

I always live so much exited to your video❤❤❤

Piękny film, dziękuję ❤

It is truly remarkable to witness. I had the opportunity to personally visit the pedestrian bridge, and I highly recommend that anyone who has the chance to visit the Tower Bridge Museum should definitely take advantage of it.

How have i only just found this amazing channel

tHIS IS AMAZING

Love the animation details keep up thegoodwork

This bridge is true a masterpiece of engineering

Thank for amazing content.

Would it be possible for Britain to design and construct something of this complexity in this day & age ?

There are two good reasons to lift the trunnion load. Neither is simple load relief. The first it to prevent "fretting" (basically, scuffing of the trunnion and/or bearing at the contact area). This can happen if the load squeezes or wipes out the lubricating medium and the trunnion-to-bearing contact area is subject to vibration. The second is to allow lubrication to get to the load area. The trunnion load is concentrated (in the animation) roughly between clock positions 7 and 8. In the real world this could wipe lubrication off the trunnion-to-bearing contact area. Lifting the trunnion allows lubricant to flow into that wiped area. Similarly, double acting reciprocating compressors must be designed so there is "rod reversal", that is, the connecting rods must lift away from the cross head bearings for about 45% of each crank revolution. Other wise the bearings can overheat and fail due to loss of lubrication.

Great video. Great use of animation.

Amazing ❤

Fantastic video: both mechanical and civil!

I'm surprised they didn't get the hulk to destroy the upper walkways 0:11

can you maybe just edit the direction of rotation on the pinion gear @ 5:29 😅 other than that excellent video

Thank you

I would greatly benefit from a detailed video on Air Handling Units and sewage treatment plants, covering topics such as their functions, components, and their significance in various industries. Given your expertise, I am confident that your insights and explanations would be incredibly informative and valuable.

Awesome video. Thanks 🙌🙌👍👌😊🍀🍀

How does using hydraulique pump, hydraulique motor with the vannes tha come along is more straigth forward than transmission ?

Superb engineering model 👌👌👌👌

You guys said youd do a video about tower 7, is it still coming?

You can also make a video of how AMT automated manual transmission works

good luck and thank you so much

Lot's of love from 🇳🇵🇳🇵🇳🇵🇳🇵🇳🇵❤❤nepal

thats simply build, best rule: make something as simple as posible, introduce complexity and the failure rate increases... simple yet effective lesson !

Great video 😊

It's amazing

I wish someone would teach accounting like this

Hey can do a video about rotary union and it's application in excavator. I wonder why does the hydraulic lines and power cables does get tangled when it rotates

Please please please make a video about sensors and how can digital numbers zeros and ones can be transmitted as waves, and how can you use zeros and ones to give a message of high voltage and low voltage, such as radio waves that transmit sounds with different strengths?

What software was used for animation and where did you get blueprints

Those British are incredible engineers!

great video

11:16 A joystick that controls the opening and closing of the bridge? I would have way too much fun with that! 😁

Where have you got this idea?

when the wtc7 video will be released??

❤❤❤

I'll take third, you two can fight each other for first. 😊

can u post any electronic and electrical or mechanical based videos. many videos based on civil, like bridge, dam and buildings. please upload any electronic or mechanical

Hi from Uzbekistan 😅

Very interesting within 5 minutes the bridge is up and down. What power engine is used on inauguration and what engine has these days the London Bridge.

Fyi,in Malaysia the Terengganu state.We also have the Terengganu drawbridge that also lift up the bridge.

U even share the model file. Thanks

100 years ago: we build things to last now: yeah... the bearings are sealed so you're going to have to replace the whole bridge

Can you please make the explaination of the construction on India' s atal setu bridge

Make a video about Howrah bridge ❤

👏🏼👏🏼👏🏼

More videos on civil engineering

I thought I was going to show the old method that used the power of the Thames

I have a similar idea. Anyone know where I can pitch it?

For some reason I always thought this bridge opens when Chuck Norris flexes his bicep.

OK... so slightly confused... I visited Tower Bridge last year, and the tour was full of references to elevated water tanks that raise the bridge. Walked through several pump rooms too... so was this how it USED to be elevated? Yeah... the walkways ARE in use too... I was up there when the bridge opened. :D UPDATE : Yep... new system installed in 1974.

Great video BUT it is not true that the walkways are available when tower bridge is lifted. Today if you want to access the walkways or steam engine room, you will need to purchase a ticket for the Tower Bridge Exhibition beforehand. It is not free it is a premium option.

0:06 - Except the walkways (or maybe just one) is actually open as a tourist attraction with glass floor. So, people do use it.

How foundation work done

Hydraulics have probably done more for mankind then electricity, and I doubt our modern electrical grid would've never came to fruition without them.

0:10 10 seconds in im questioning why i clicked this video

Hydraulic fluid gearsss 😁

this is why I don’t go to sleep

This is the tower bridge

Lesic indonesia kenapa tak upload upload mamang sabin😂

Both professors spoke english, but I still need someone to translate

Animation of the load on the bearing is wrong. It's upside down

Is hydraulic power the most powerful torque humans have available?

Bet that hasn't got any potholes on it 😅

Now they charge tourists to go up the walkway

Hindi version please 😢

at 4:34 it is 20th century not 19th century

some engineers even hundreds of years ago create really nice things meanwhile lots of other people remain lazy and dont want to think or work

/e pin

You can compress and make your voice loud some more. So bad!

Just Keep Maersk away from it

6th comment 😅

It’s a tower bridge not London

Someone stealing your video: ukposts.info/have/v-deo/haWYi6uObK2Luok.html

Firstt

first pin me pls

This video was Hindi language please

I know many people are going to get annoyed with me when I say this stop using stupid sponsors as they are scam artists

you are indian so why don't you make a video on chenab bridge. I think it will go viral as no one has made it till now

*skips Indian guy’s boring and unintelligible ahh explanation

Unprofessional standards using childish cartoon sounds.. SSSSSSWWWWWWWIIIIIISSSSSSHHHH / ZZZZZAAAAAAAPPPP to the dislike button jr

Yeah very amazing waste of steel and iron. If humanity doesn't start mining elements from asteroids in 200-300 years, it will be the first to be scrapped.
