Ok

Hello @RealEngineeriny i am an english speaker, but the video is in french for some reason. Since you started using narators, i cannot listen to your videos. Is there a way to change the language?

love your content, keep up the awesome work!

​@@frenchy3688settings of the video, audio track

Yeah and then they proceed to unscrew a cow from previous tests😂😂

​@@joebob2738 you can take the cow off the stand. but you can never unscrew it

I see a lot of creators make a second channel for content like this if they make it often, I've always liked that approach.

@@lethena6249 yeah I fucking love creators second channels for shitposts, helps remind me that they're just normal people like all of us that love shitposts too, there's just something so beautiful about shitposts, like when a game feels like an absolute shitpost like kingdom of loathing I fucking love it

This is science because it's recorded

@@tylerv9174 science and shit posting aren't exclusive. The best shit posts are from skilled and intelligent people, because even their shit posting is fun.

@@lethena6249 I agree that that'd be the right approach for this. Real Engineering has a specific format, and with Real Science it seems like that format is basically codified. It'd be great to have a second "Brian McManus" channel for stuff that's different. That being said it's his channel and not mine so whatever lol.

jesus woah

Yo, thanks for creating laws of physics, bud!

Shoutout to your dad for making physics fun!

I might agree this was super fun :D

Stupid, fun, and somewhat educational? I see this as an absolute win!

Best video

Yup.

stupid can be the most entertaining especially with smart people

People named Eli are the best.

Idk man he doesn’t seem that smart. Probably has no clue what he’s doing most of the time

​@@patrickhughes9094A lot of smart people have no clue what they're doing most of the time. You can't be afraid of not knowing what to do, or you'll never learn

​@@patrickhughes9094wow, you insecure much? I don't see you working on a hypersonic wind tunnel

Uhaul rocket model when?

Spoiler alert.

I felt that.

I also thought they had some crazy cool laser activated bell....

@@oracleofdelphi4533 if you are worried about spoilers don't read the comments

My initial thought was that they had a complicated system of lasers that somehow activated a bell. I guess that's cool too though.

Totally, not too bad on the eyes either... 👀

Fluid and aerodynamics are interesting fields with even more interesting designs.

Can't wait until the government weaponize it.

It did not survive the full test. It is splattered in million pieces inside the vacuum tank.

What if you had a De Laval lane architecture? Traffic can be modeled by fluid dynamics.

@@dongiovanni4331 yea in cases analogous to a De Lavel in traffic, the sudden shift from a constrained number of lanes to open road does increase speed. Just think about every time you've been on a highway that suddenly cuts down to single lane traffic then opens up.

@@travisbeagle5691 Traffic isn't quite fluid-dynamics like, mostly in that it follows discreet lanes, but there are certainly similarities. De Laval nozzle certainly is a good analogy though, as the "mass flow" is limited by the rate at which cars - at a "choke flow" velocity - go through the narrow spot, and "back pressure" - the density of cars or size of the traffic jam - before it doesn't have a huge influence on this.

I laughed so hard at the flip and explosion lol

Yes, this animation was crucial.

What we actually need on highways is venturi flow. Half the lanes = double the speed.

@@appa609true, except for crashes. We just need trains

​@@appa609i will settle for laminar flow. (No crashes, no cutting people off, no sudden lane changes) But also we need better options than just highways. The highways will always exist for military reasons, but functional trains would take so much pressure off of them.

Ew…a NJB cultist

It was obligatory, otherwise there'd be a hundred identical comments saying "Not Just Bikes would disagree."

Having gone to engineering school, I concur. Every engineer has had crazy and stupid ideas they'd love to explore but has no practical application. Or how they would solve any "problem" no matter how absurd or horrible. Probably every engineer has thought of how they would destroy the world if they had a reason to - most don't have a reason to but I'd recommend not giving them one. I recall discussing over several weeks with a college swing dance friend (if I remember right she was a forensics major - similar in this regard but even more dangerous) how we would go about flooding only the upper floor of the student union - not something we would ever actually want to do but our plans for how to carry it out were very detailed.

​@@Stevie-J How is it cherry picked data?, and how is it non-productive? Although i acknowledge we may value different things. Also, he might not be aware of not just bikes, so he'll just like "imma Ignore it because i don't understand it", intelligent people usually tries to understand the topic before speaking about it. (Also imagine how awkward it would be if he immediately interjects "what is not just bikes?" or "well traffic is a...", it will derail the conversation, especially infront of a camera recorded and published to a huge audience) And i don't think it's his field of expertise, (it's alright to talk about things you are not an expert in, i mean how can we understand things without discussion?), so i think he was just trying to explain it using simple analogies(like to an american citizen, i mean they are in america afterall with car centric infrastructure, they're bound to be more familiar with it), without looking at the complexities, Plus i think publishing high quality videos is already quite productive, atleast compared to commenting on youtube. Lol, In addition, the culture of production vs consumerism might be perpetuated either intentionally or unintentionally by the conflicting interest of companies vs consumers(ye unsustainable relationship), producers will probably spend less because they can create some stuff they use and can repair parts, and outright be independent. You can see how this might be a conflict of interest.😮

A comment of this quality deserves more likes

No need to attack literally everything we have ever done 🤣

@@RealEngineering We want a new Bill Nye for every cool thing XD

@@RealEngineeringlol. The difference is your stuff is factually correct LMAO keep up the great work

@@Will-uf7jt Is that an attack on Lazerpig?

@@RealEngineering I don't know what I learned, but I'm excited.

Congrats on being the first person to say that sentence.

yeah this video is different but in a good way

What's perhaps most interesting - and surprising that this wasn't mentioned - is that the shock waves actually did pretty closely resemble the flow lines shown on the uHaul truck graphic that inspired it all. As for a uHaul sponsorship, I think they want to avoid encouraging people to drive their trucks at hypersonic speeds, though I know we've seen some people attempting to do so. A Nissan Altima would probably be a more relevant test for a vehicle people attempt to drive at hypersonic velocities on a regular basis. I hold that an Altima is actually a faster vehicle than a C8 Corvette - the C8 (driven by a retired Boomer) goes, at most, the speed limit, while the Altima (driven by a nearly-broke 20-something) goes 15-20 over, at least.

@@quillmaurer6563I think it's region-specific. Where I live it's the pristine Ford F150's clearly driven by someone over 40 that get driven 20 over on the highway. No matter who they have to run off the road to go that fast. Weirdly it started pre-pandemic with a lot of Texas plates (I'm in Missouri) and only a few local. Now it's almost anyone in that kind of uselessly oversized truck. As for the teenagers, the used car market here is mostly Ford, Chevy and Toyota, and the used ones have inflated so much that young drivers can only really afford those held together with duct tape and running on prayers and burning 15 gallons to the mile, so they aren't the racers they were when I was young.

@@Merennulli True. The Altima thing is more based on stereotypes, I've not actually encountered too many of those. The needlessly big trucks with super aggressive drivers is a major plague in Colorado as well. Certainly an attitude of rule-by-intimidation rather than obeying traffic laws. So maybe it's F-150s are faster than C8 Corvettes. I just know the slowest thing on the road are Toyota Highlanders and late-model Rav4s, driven by people who have zero interest in cars and driving and want to put as little passion into it as possible.

I would love to stick my arm in there. Of course, I am studying nuclear engineering, so I probably will not be sticking my arm into anything, other than maybe a rod control mechanism.

I'm surprised they'd have undergrads to it. To the university they're walking burlap bags with dollar signs on them, and pretty much useless for anything else. Grad students are the slaves used for this sort of stuff, and I could even imagine a professor deciding to take on a grad student in part because they're small enough to get inside equipment the professor needs serviced.

Don't misbehave, or you will be put into the vacuum tank. 🤣

Have in mind that while adding lanes does not help reduce travel time for their customary users, it does increase throughput, meaning more people are able to use that route. The new users do get a benefit (otherwise they would go back to their previous route). So there is a net reduction in travel time, it's just that probably smaller than thought, and coming from a different side (slower alternative routes being used less).

@@MrTomyCJproblem with that is that highways cost a lot and use a lot of space compared to public transit

Triggered? Not Just Bikes is a friend of his, can't see why he would be triggered by getting a free shoutout.

@@RealEngineering Woah Language!!

@@RealEngineering fair haha My AC has been out for a week and lemme tell you i don’t under-appreciate that miracle invention anymore

Arduino's are quite robust micro controllers to be used for science instrumentation.

It works, it's cheap, and it is damn easy to work with.

They said it's just a part of the camera triggering mechanism and they could run the test without it, so it wasn't actually critical. Besides, a properly-used Arduino is arguably no less reliable than some other microcontroller on a custom PCB

Aerodynamics is the only part of physics where assuming a sphere doesn't work.

Lol, apparently brilliant minds think alike..😏

m.kzfaq.info/get/bejne/jN-ogL1j27mXlH0.html

and naturally, they still fail at the rate of arduinos. but that's okay because grad student time is cheap, as my advisor would say

It's so specific and engineering dictates to choose the hardware specs based on requirements. For reading a couple of values and sending them out a couple hundred times a second, an arduino is a sufficient and simple solution that reduces development time.
