"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.
Physics does not work that way goodnight!
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. 🪿
#longTonConspiracy #longTonCon
Reminds me of the Canadian Conspiracy Convention, CanConCon.
But can Ken can the long Ton Con on the CanConCon?
Sure you can build a bridge they can withstand a crazy like that. It'll cost more than the cities it connects and nobody has a budget for that.
Pfft, just put big magnets on either side of the bridge to make sure it goes in the middle!
Magnets stop working if they get wet, like under a bridge
Fire.
You see, gravity is just a theory see.
Bro, it's a trillion ton bridge. You're comparing a bug flying into a windshield and telling me the windshield should break. R u serious 4 real?
Huyuck. Sorry for that. But this is the kind of shit you're going to have to deal with. So you better have an answer for it.
"If I hit your kneecap with a hammer, I'm only taking out one support, but your hole ass is hitting the ground" seems like a good response
