There is a saying in engineering.
Anyone can build a bridge.
It takes an engineer who can build a bridge just strong enough to let cars cross it.
Oh man, as a (non structural) engineer I love the saying
“Any asshole can build a bridge, but only an engineer can barely build a bridge”
I’ve heard it as “Anyone can build a bridge that stands, it takes an engineer to build a bridge that barely stands.”
Never heard that one. Sharp.
Razor sharp, just like the safety factor of that bridge
Wait till you see what the airplane and rocket guys have to do.
“I just don’t see how the whole bridge falls over that fast”
Bruh it is a ten million ton cargo ship bumping into it, do u think it’s just gonna bounce off?
That ship was about 100,000t.
There’s a fairly crude equation in the American bridge engineering standard that relates impact load to the mass of a ship, which is:
P =√(DWT) ±50%
Where DWT is the deadweight tonnage, and P is the impact load in meganewtons.
So in this case P=315MN ±50% which is 315000kN or 31500 tonnes of force…
For comparison, I’m working on a project where we’re going to build a new concrete bridge on the ground next to where it needs to go (under a railway) then wait until we have a planned week with no trains running and push it into position using jacks. That bridge is a 60m long 20m wide 8m high concrete box with 1m thick walls and top and bottom slabs, and we think we will need about 30MN to install it (one tenth of the impact load from that ship).
So yeah… that’s quite a hit.
Yeah but long tons or short tons. If they used shorter tons maybe the boat would have slipped right between the leg things. The tons were too long. 🪿
Yeah but it literally floats so how heavy can it be?
it floats way better than i do, so it can’t be that much heavier than i am. and let me tell you, there’s no way i could topple a bridge by running into it
I get all my bridge information from Andrew Tate and Alex Jones.
They’re both certainly people who know how to burn bridges when they see them.
They’re also both people I’d like to see jump off one.
So all in all, they should have a lot of experience.
All I know about bridges is how to sell them, and I have one right now I can guarantee was built by an entirely white construction team. I examined their skull shapes myself. I’ll just need about $80 million, and it’s all yours, Elon.
Dude this thread has some of the funniest comments I’ve seen in a while and this one.
I mean, all it takes is a look at the cost of shit like tuition and text books to conclude college is a scam, but that doesn’t equal a disrespect for the knowledge of people who’ve gone through it.
I have had more PhDs recommend against college than for it. I’m not joking. It’s scary.
They’ll tell you that if you can get by without a degree, by all means do or at least heavily consider it.
Education is undoubtedly important, as often evidenced by people’s lack of it. But even those who ran the gauntlet decades ago have lost faith in the system.
And now we have a whole new litany of problems on their way because of the rising prominence of GenAI and I can confidently say that academia is wholly unprepared for the shit storm coming it’s way.
We always seem to equate common sense and education.
I’ve met some dense people with PhDs. And some smart people that never got formal education.
Obviously best case is smart and educated. But you can’t teach someone common sense.
Wish Lemmy had some sort of awards, because also this exactly.
Just out of curiosity - which country was your sample from, if I may ask?
US. So perhaps not representative of international trends. Altogether worrying with implications for US education standards though. The whole college/trade/career decision logic among the US public is seriously out of whack because parents kept preaching it was either college or burger flipping, unless you had a talent or parents with money of course.
The US education system, academia, and workforce are all incredibly and seemingly unappealably fucked. The bigger picture is just some madman’s abstract expressionism. I’m convinced the Russians are behind it all, somehow because just wtf it is actually looney levels of destabilizing and I fear it all comes crashing soon enough. But whatever, stop worrying and love the bomb I guess.
Basically, America’s poorer majority have the free choice which rich conglomerates they want to be exploited and/or drained dry by? Legalised wage theft, student loan debt, ludicrous cost of privatised healthcare - spoiled for choice which monopoly to hand their entire fortune over to, really…
Pretty much. I had to explain to my mother on the phone last night why I absolutely refuse to order anything from Amazon if I can get it brick&mortar without any issue and she couldn’t understand it. “You’d rather pay more? Why not just wait the couple days for shipping?” That’s not it mom, yes I like being able to immediately receive what I paid for in a transaction, as well as the opportunity to inspect it’s package before I pay for it, but that’s only the tip of the shitberg. I will gladly go pay more elsewhere because that money is often times going back into my community in at least some fashion and I can trust that my experience as a consumer will be better when I shop with the little guy who says my patronage matters and that they appreciate it rather than the unaccountable tech conglomerate that got its start by exploiting a flaw in a book vendor’s billing system for their own profit.
“I’m voting with my wallet” “…by paying more elsewhere” “sigh yes mother that’s how this often works, welcome to late stage capitalism”
What the hell are people debating here? A 150.000 tonne object crashed into a structure made of thin sticks (comparatively speaking). There is no doubt that the bridge would collapse. Especially since an arch is only stable if it is undamaged.
Unrelated to the content, only to the format, but what odd iteration of Facebook(?) or its like is this from? Is this the mobile interface of FB these days?
That’s definitely the official Facebook app, using dark mode. Looks just like mine, right now.
