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?
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
But that could mean the ship is actually a witch! And witches do have a history of bringing down bridges.
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. 🪿
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.
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.
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.
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.
Ok so the bridge collision seems like an obvious accident to me, no questions there from me.
But that photo of the truck I can't figure out how this happened and I suspect aliens and/or bigfoot might be involved somehow.
Im not sure im going to explain the well, but...
I think they backed into the pole and it bent the bar (or whatever that guard thingy is called) up and under so much so that the pole ended up behind the bottom rail of the bar. The metal bar, then, spang back into place somewhat. And the pole "bent" / angled backward (from the ground). When the trucker tried to moved forward to get off the pole, the pole got snagged in the hole due to the spring action and got ended up getting dragged back to its more upright position, and it ended up as you see it in the picture.
I dont think the hole in the ground from the pole is from it being dragged forward, so much as from it being pushed backwards.
Edit: someone I know that has family that drives trucks says that it also could have occurred if the other trucks on the side weren't there to begin with and the person was trying to turn and the trailer swung out and the pole got dragged past the first hole and into the second hole. I'm kinda skeptical it could happen that way considering the direction the pole was dragged in the ground but who knows. it's just another perspective. But he also thinks the picture is photoshopped so...
It makes sense that the trailer backed over the pole so far it got under the bar. But the trail behind the pole indicates that it was dragged forward. It seems like he backed over the pole causing it to bend and go under. Then moved forward causing it to poke out above the rail and then it dragged forward causing the asphalt to be ripped up the way it did.
But why didn't the bar break? It must be made of alien materials!
And who put the pole in the middle of the parking lot? Probably bigfoot.
Bigfoot is working with the aliens confirmed!
I don't think Knowledge is a scam, but I firmly believe that the current College system(at least in the US) is a scam or at the very least super predatory, it's one of the only types of debt that you can't bankrupt on, and if you try to go for anything more than a bachelor's you're likely not going to be able to pay off the loan due to interest accumulation.
I would say predatory is the right word, unless you have money.
Although I would not put most community colleges in that boat.
Shame that a lot of universities are starting to ban credits earned at community colleges. Can't get any more predatory than that.
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.
Engineering is one of the few non-scam college degrees
And what are the apparently majority scam degrees?
You’ll get a lot of people arguing arts degrees where there aren’t jobs are scams.
Frankly, I think there’s a divide between what we expect of education and what education should be.
There’s kind of a spectrum from required credentials like medical, law, or engineering degrees, to things like stem programs which are not required but open job doors, to arts degrees where there’s not really many direct careers being opened.
Charging an arm and a leg for arts programs is a scam because it’s not opening the same economic opportunities as career based degrees. Having or providing arts degrees is totally fine, they just need to be cheaper.
I think the main benefit of an art degree (for the average person) is learning to research, communicate ideas, and think critically. I have a degree in political science and work in an IT/business role but I absolutely don't regret my choice of degree.
My Bach degree was in history, and I often wrote off the importance of the “critical thinking” skills we learned in that program.
Boy was I wrong, I know too many people who need nothing more than an unsourced headline to fully convince them of something ludacris.
So the correct spelling is ludicrous, but I prefer to believe that you really did mean to refer to American rapper and actor Ludacris. So carry on.
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.
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"
