Dope Tech Episode 2

<<@oliverray58 says : The no-gaps rock system sounds stupid. RETVRN to Thathak Thathak>> <<@codeninja1832 says : How many sections of these rocks would need to go missing before the tracks buckle? Asking for educational purposes only.>> <<@travissmith2773 says : He has it backwards, track is removed after install to put the trak under tension>> <<@BennThomPson-o4s6k says : Very Interesting Brothè..👌>> <<@Chikoo619 says : I don't get it. Weren't the rocks there before too? When we still used the gaps?>> <<@Fluteboy says : Kedeng-kedeng Kedeng-kedeng Kedeng-kedeng 😉>> <<@Haja024 says : Seems fake. I say that based on Vibes(TM). The Vibes tell me the buckling of loose rocks is weaker than the force of steel tracks expanding. I checked the Rail stressing article on Wikipedia and the vibes were right, as they usually are.>> <<@Bobfahrer says : You make shorts now? This channel has fallen from the greatest heights to the lowest lows.>> <<@mythilikarthikeyan7748 says : Thadak thadak 😂😂>> <<@Ankitwhytoexist says : noway in hell I saw vande bharat in a veritasium video>> <<@FalconPlayZz says : Who thinks of stuff like this>> <<@neekadoodles says : Sell outs>> <<@JoãoLeote7331 says : Engineers really putting the integrity of the entire rail in the hands of some rocks>> <<@SorryMyNameWasTaken says : Randomly was thinking about rails the other day and why they need rocks and the wood blanks between the actual metal rail in the first place, and so this really scratched that itch. I wish America made more rails instead of all the massive highways and roads for the cars :(>> <<@TreeSpeakerGetsTheMagDump says : Sell out channel>> <<@rnrgaming4579 says : Well... doesn't the friction eventually round the edges and lead to the same problems? Or is the time scale of this event long enough to just not worry about it?>> <<@JohnHowell-t4t says : Rocks are called rip-rap.>> <<@Gumbocinno says : I'm guessing they're jagged so they don't have an ability to jumble around from the vibration. I'm locking the answer in. Gonna watch the vid now. Alright I think nearly nailed this one.>> <<@zTorrentiaLzzz says : Well really, the rails are ‘stressed’ prior to welding in to compensate the heat>> <<@CHMichael says : So that's simply not the case ... thank you, comment section>> <<@CHMichael says : So that's simply not the case ... thank you, comment section>> <<@Socrates-0001 says : Dude that rocks>> <<@MultiKeto says : i miss the clickety clack>> <<@gonzoengineering4894 says : Hahaha, no there's still plenty of jointed rail in the US>> <<@lowspeedhighdrag566 says : Rocks are based AF.>> <<@danvanf says : RR ballast was always jagged having nothing to do with welded rails.>> <<@colinmacvicar2507 says : They also pre heat the rails before they weld them. So when they are hot they are in a more natural state and when they’re cold they’re stretched out.>> <<@Roadrunner99942 says : When did they start welding them together. As a kid I remember that very distinctive clunk clunk clunk. And I'm not 100 years old>> <<@user-bf8ud9vt5b says : Plus, it’s soooo much work to round all the stones.>> <<@JwaEditz says : Or B, just cement the whole thing to the ground>> <<@michaelbalfour3170 says : Roads, houses, paving all use this. In the UK we call it hardcore or type one. Sometime a lattice like weed barrier is underneath to add extra structure.>> <<@jackpfefferkorn3734 says : I assumed they were the cheapest rocks available, waste from a quarry or something.>> <<@WoollyMammoth360 says : The rocks are called ballast>> <<@Terranaut_67 says : I lived across the street from an old B&M RR track. I always wondered why those ballast rocks were so tightly packed and difficult to pick up :) I never understood the physics behind it :)>> <<@hippystyle6551 says : Yuuge internal pressure>> <<@PROofHAPPYWHEELS says : Wont the rocks smoothen over time?>> <<@Noh_Mercy says : so if someone dug up the rock around the tracks would you see the rails snap right there?>> <<@nateborden3260 says : In two words tactile friction>> <<@ElAnvaBar says : If they dislike the clickity clack so much. Why don't they just stagger the cut?>> <<@aer2755 says : Wrong! It's not the rocks. Even before the tracks were welded together there were aggregates on the lines. It's the new lock mechanism that replaced the nuts and bolts that were used to secure the rails to the sleepers that enabled welding them.>> <<@stupid4u says : My favorite moment of the video has got to be the thaduk thaduks>> <<@xDJxGNOMx says : So do they need to get replaced after a certain time? They eventually round off right?>> <<@Skaconut says : I feel somewhat certain there is a lot more to this than “not do smooth rock”>> <<@coledavidson5630 says : So... rails are just ticking time bombs, itching to buckle under their own internal stress but unable to until erosion wears the rocks smooth? That's terrifying>> <<@Zyphera says : I miss that sound. It made it easier for me to fall asleep.>> <<@ericpmoss says : Has anyone been researching alloys that have a lower coefficient of thermal expansion? I know there is INVAR, but I don’t know what its other properties are.>> <<@johncenegal says : gonna go pick up some rocks hehe>> <<@abaddon3863 says : Nah they still expand at the very end of the rail the entire length can grow up to 200mm for a hot day>> <<@ChaitanyaSayi says : VC channel>> <<@झुरळ says : Vande Bharat got a cameo ❤>>
