I knew about seismic dampers already, but what really impressed me was how well the physics system of the game simulated it. I really, really didn't expect it to actually work lol.
Your explanation of seismic dampeners was amazing! I never knew that buildings used those to stay up during earthquakes. That's so cool! Thanks for opening my eyes to the world of civil engineering.
Maybe you've heard that Taiwan is famous for their frequent earthquake. The big ball in the video is actually inside the Taipei 101 in Taiwan. That saved the building from several strong earthquake already. That's why a bid ball is always good!😂
The lesson about seismic dampeners was a real treat to listen to. The visual aid of what you've done in the game really puts into perspective how the mass damper at the top of Taipei 101 works to protect the building.
Okay, for real, if the makers of this game were hoping to teach people mind blowing engineering principles.... Man, mission accomplished. I'd heard about sismic dampers before but really just couldn't fathom why they work or, further, if they really could be all that much better than traditional bracing.... well hell, now I know! Amazing demonstration! Thanks for taking the time to showcase all the "less optimal" approaches as well, I don't think it would have had nearly the impact otherwise!!
You know, this might well be class room material. I know my kids watched this with interest, also because of the Enjinir wobbling about, but the concept is well laid out. Kudos for that Matt.
All the builds before really showed just how good it is though. He used his example stilts structure, added cross beams at the top center, and the block. It stayed together better than anything else.
What is the old saying? Keep It Simple Stupid So the counterweight design was the simplest amongst the ones shown, thus why the other saying “if it is stupid but works, then it isn’t stupid.” A saying you can annoy your friends, family and or coworkers with if you find a stupid solution to a problem but just works enough not to be stupid. Lol.
I mean, it's literally in the thumbnail :D but yeah, it was a great demonstration and visualisation of different engineering techniques. Really solid video
The effectiveness of that counterweight was amazing, that last tower was rickety as hell, I didn't think it would stay up even without the earthquake and yet it held no problem thanks to the counterweight.
"we will spread the force to the other leg, which is spreading its force to this leg, so there is no reduction in force at all, just an increase in weight" RCE building code, chapter 1
Every joint is somewhat flexible, and that flexibility can absorb a portion of the force, and convert it to heat (although in this game, temperature likely isn't simulated, instead, there is probably some "flex resistance force" that is countering it)
it reduces the force on each beam at the expense of overall weight and increasing the force on joints, but its cheaper to make joints stronger than the entire beam.
Yeah he didnt explain how it's not that the beam itself is breaking, more the joint between them. That and then also the fact that he DID mention, that it reduces flex.
It was these kinds of learning videos, bridge building explanations for example, that made me watch RCE. Actually enjoy them more then the poo/''strongest shape'' focused ones. :D
Agreed. After a while the joke does get old and I actually really enjoy all these educational bits that showcase his actual knowledge through the medium of gaming far more!
Same principle in bridge building. Lots of the worlds worst bridge collapses were due to them making bridges super rigid, so when some freak winds came it caused them to buckle and break. By making them "looser" and letting them sway, you dampen the effect of wind or uneven weight which counterintuitively makes them stronger even though most people would think a non-rigid structure is surely weaker.
At the top floor of the CN tower there is a plummbob that hangs from the ceiling and it looks like it is moving back and forth, but in reality the whole tower is moving around the bob. Your solution totally reminded me of that!
I've known about seismic dampeners, but I never realized they were so high up. For some reason, I always thought they extended all the way down near floor level. Well hey, come for the knob jokes, stay for the engineering lessons. Ya win either way. Cheers!
I'd love to see more of actually educational videos like that. I do really enjoy your channel and having something like this in addition to all wonderful stuff would be something else.
This is one of the most educational videos I've seen in your channel. It's very interesting to watch. If only real lesson could be as interesting as this 😂😂😂 The real-time demonstration and everything. Simulators are the way to go, mate
Fun fact: something quite similar to the seismic damper that RCE explained in the video was used in F1 for a short while (although known by its other name, tuned mass damper) this allowed for the nose of the car to be more stable over bumps, improving the efficiency of the front wing! We mechanicals might joke around and make fun of civils from time to time, but these guys have been around for just as long as us, and have invented a whole lot of stuff that is taken for granted nowadays
Cross braces are also necessary to control the spread of tensile vs compressive loads, since steel/wood and beams in general are not the best under compression...
I think the version with the wheels might work if you used ropes to connect it to the ground, they would allow the whole building to move on the platform and keep it centered at least what I think In my mind
To the supports along the steel column, will reduce the unsupported length of the beam, and can prevent it from having a failure mode other than a regular bending such as torsional deformations. The change in the unsupported length also allows the beam to acquire more load while having a smaller deformation.
I love how the thumbnail isn't clickbait at all for once because he actually used engineering principles to build a tower that a normal person wouldn't have thought of.
this was a better engineering lesson than any of the ones I had in college. I swear if engineering was taught like this, I'd have my masters in two years flat
This is awesome, I didn't know about counterweights. And was so impressed that it worked that well with limited beams. it's true that flexibility of the structure is essential. (There is actually a magic school bus episode about it (the new one) where they equates building the building to a tree that flexes in the wind) This flexibility need is also why wood works way better than blocks. Blocks are brittle. Wood is also lighter than blocks and this helps because the equations for calculating the horizon forces on the bottom uses the weight of the whole structure above it. Anyway, great video! Thank you!
This could be an interesting class about inertia and the lawa of Newton! Really it's inertia that keeps the building in place, both with the counterweight (which stays in place because it has such a big mass so it has a lot of inertia) and the "wheels" (which allow the building itself to stay in place thanks to its inertia because by reducing friction they prevent the movement of the platform to be transmitted to the building). Awesome!😊
Absolutely loved the way you went through the various methods of seismic dampening. Almost felt like a history lesson in engineering. The way each time it improved but ultimately the most simple design was the most effective was incredible to see. KISS it. Keep it simple stupid
Not gonna lie that really impressed me, the way that you don't need any kinds of braces to make the building strong but only needing one dangling heavy piece in the middle is enough to counter an earthquake impresses me a lot
Ngl, I wasn't expecting it to work in the game. Also, I knew mass dampers were effective, but damn. You didn't even brace the columns. I didn't know they were that good. I even thought the block was gonna hit one of the columns 😅
I love how the game literally gives you the option to place lines to help you align things properly and instead, Matt just roughly guesstimates things and ends up with the most crooked constructs known to man.
Now, you see, this shows you the basics of civil engineerings where we use a central core to stabilize the entire structure. **Building vibrates itself apart** I hope that gives you a good understanding of why we build these central cores of concrete.
Seriously, this video is like legit course in civil engineering. You should consider being an engineering lecturer if one day you get bored make gaming vids 😂😂
Day 13 of waiting for Matt to upload Mindustry Part 3. FFOTD: The turrets that repair units is the Repair Point and the Repair Turret (that's what they're called), the Repair Point has 40 hp, is 1 by 1 blocks. needs 30 copper, 30 lead, and 20 silicon to build, uses 60 power units per second, has a repair speed of 27 per second, and a range of 7.5 blocks. The Repair Turret has 205 hp, 2 by 2 blocks, needs 80 thorium, 90 silicon, and 60 plastanium to build, uses 300 power units per second, has a repair speed of 180 per second, and a range of 18.12 blocks, and it also has optional boosters: water (9.6 per second) makes it 1.64x stronger, and cryofluid (9.6 per second) makes it 2.44x stronger.
_"Hopefully you learned something today."_ - I did, actually; never heard of seismic dampeners before, now I have at least some cursory knowledge about them.
What a fantastically entertaining yet very informative video. This is what I wish RUclips was. You wouldn’t have to choose education over entertainment. You can just learn the best way to
Cool. My grandparents house in Japan uses seismic dampers, in the form of rocks. Cool house, very old style. Also at least one old af castle over there with massive tree used for the damper
Everyone talking about how cool the explanations are, the science of it and all, meanwhile the whole video I'm just thinking "well of course it's breaking, you've got stilts stacked poorly on top of each other held together by just a couple of nails". Unless you include something like the dampener that lets even super weak setups work, the shoddy construction was bound to fail. In the first design, most of the time the points of failures looked like it was where the stilts sat on top of each other because while the side to side bracing got better, the actual connection between each "floor" was barely there. Improving that wouldn't have helped a ton, (again especially compared to the seismic dampener), but it definitely would have held up better.
Honestly this was really fascinating. :D Matt with seismic dampening *gesturing to the other solutions*, Look at what they need to mimic a fraction of our power!
That is genuinely ingenious I'm no engineer but I was thinking "no flipping way adding more weight was gonna work what are you on about?" But then it did lmao
Maybe a triangular structure with angled supports then inverting the structure to balance the top then adding a dampener could be a good idea. I feel like the straight up and down beams and the 4 faces make it harder to not transfer a lot of motion into the structure.
good grief I had no idea. I have an irrational fear of going in really tall buildings because I can tell they DO sway, but it's reassuring to see that's both intended and much better than the alternative
The dampener's purpose extends beyond just earthquake mitigation. In a 100-story tall building, wind effects at various levels can significantly impact the structure. Therefore, the dampener is also crucial for counteracting these wind forces, in addition to other natural frequency disturbances. I'm not a CE, but a ME 😂
I knew you were gonna build a tuned mass dampener as soon as I saw that there were blocks and ropes. Though I expected it to require a lot more tuning.

It was the fisrt solution that I thought. Buuut I said to myself "the won't simulate this correctly"
I'm shocked now with the final design hahaha
I was kind of about to say something similar
Yeee, idk if u know this already but the 2 creators of this game r engineers aswell so that may kinda explain it to an extent haha
2:33 "skyscraper exoskeletons" Great, now I'm imagining a cicada the size of the empire state building
I love how every once in a while rce has to do an educational vidio to prove that he's not an architect
Indeed.. I'm suprised with the last method...
"Vidio"
Goeiemorgen robert, hoe gaat het er mee😂
Goed
This is exactly what an architect would do to "throw ppl off the scent of truth!"
Your explanation of seismic dampeners was amazing! I never knew that buildings used those to stay up during earthquakes. That's so cool! Thanks for opening my eyes to the world of civil engineering.
I am impressed the games physics engine worked like it does in the real world.
ngl this is a great educational video
I'm saying as a beginner IT engineer but I've no intention of going for Civil Engineer 💀💀💀
You learn about this in year 8 geography
Maybe you've heard that Taiwan is famous for their frequent earthquake. The big ball in the video is actually inside the Taipei 101 in Taiwan. That saved the building from several strong earthquake already. That's why a bid ball is always good!😂
Ah yes.. a successful prevention of architect genesis
The lesson about seismic dampeners was a real treat to listen to. The visual aid of what you've done in the game really puts into perspective how the mass damper at the top of Taipei 101 works to protect the building.
Been there once, that duned mass damper is huge! Love from Taiwan

Rce should definitely become a teacher at some point in his life!
I sat here this entire time HOPING you'd get to the counterweight. It's amazing what something fairly simple can accomplish.

Okay, yeah, that was actually awesome! Really cool to learn how buildings are designed to weather earthquakes. Such a clever idea, the dampeners...
Seismic dampening worked soo well with the physics of the game😮
Loving this series 😆
11:58 those seismic base isolators are the strongest shape, that’s why engineers use them in real life

This game is bringing out the best of Matt. Glad to see real engineering translate well in a game!
I especially enjoy an RCE video when he's kinda using a video game as a means of teaching about engineering and physics and all that kind of stuff.

I am just amazed by the final design working with almost no support , feels like it should be collapsing but it just didn't
thats really cool how you showed what you can do to make things stable and teach about seismic dampener's.
This was legit a college lecture. 10/10 enjoyed.

Usually things like these in videogames don't work
I didn't know they put buildings on ball bearings, so I did learn something new today!
Thank you.
_"Hopefully you learned something today."_ - I did, actually; never heard of seismic dampeners before, now I have at least some cursory knowledge about them.
As a non-engineer, I know all these tricks, but it was still cool to watch and learn, and like expand or build onto what I already know 😊

Cool. My grandparents house in Japan uses seismic dampers, in the form of rocks. Cool house, very old style.
Also at least one old af castle over there with massive tree used for the damper

First thing I thought was counterweight, but I was surprised how well that held up especially with just the twigs for legs
I do love videos like this where you can actually learn something. It's been a while since the last one...
Everyone talking about how cool the explanations are, the science of it and all, meanwhile the whole video I'm just thinking "well of course it's breaking, you've got stilts stacked poorly on top of each other held together by just a couple of nails".

good grief I had no idea. I have an irrational fear of going in really tall buildings because I can tell they DO sway, but it's reassuring to see that's both intended and much better than the alternative
I like when Matt talks about real engineering design. it's very interesting
I'm taking statics and rigid bodies right now and this kind of explanation plus the 3d representation is better than a drawing and a bunch of numbers.
The power of engineering, plus being long and wobbly, is unreasonably effective!
Thanks for reminding me of things I learned in school on my winter break
Loved the examples! Super cool man!!
Architects hate this one simple trick:

I love this! The pendulum thing was incredible. Thanks!
Great video! Love watching other civil engineers get nerdy about it.
Duuuude I was LAUGHING at the idea of that final prototype working, I said loudly "there is NO fucking way" and then I sat there mouth wide open
I knew about the seismic isolation method but I had no idea about counterweights, even though it makes a lot of sense.
Ok that last design was actually amazing O.o Like.. you are actually real engineer...
I knew you were gonna build a tuned mass dampener as soon as I saw that there were blocks and ropes. Though I expected it to require a lot more tuning.
This may be your most legitimately educational video yet.
