Bonkers isn't it? Like a Gerard Butler film. Imagine what it must have been like to be on that bridge. Terrifying. Hope all are OK.Holding the wrong end of the stick since 2009. -
Was Mothman involved? -
The physical forces involved there are incredible - that steelwork folded like it was made of tin foil. Shows how much of an engineering achievement bridges are.Holding the wrong end of the stick since 2009.

I don't imagine they have much tolerance for lateral forces.

It collapses so quickly, terrifying.
Not like the movies, no time for Spiderman to have an identity crisis. -

Yeah exactly. So much relies on the tension from the main supports and when that's breached sideways the whole thing just collapses. Seems counter intuitive that you need extra weight across the bridge to make the whole thing stronger but the load bearing comes from the top parts of the bridge and not from underneath."Plus he wore shorts like a total cunt" - Bob -
My personal preference for supporting bridges is not to drive boats into them.

Bridges are cool. -

I presume there was a failure on the boat?"Plus he wore shorts like a total cunt" - Bob -
Theres a question on design though right?
A boat crashing into a support isnt a completely outlandish situation to consider. -

I'm sure they're safer in Europe. It works pretty well I guess until it doesn't."Plus he wore shorts like a total cunt" - Bob -
Does boat fuel melt steel?

From the Grun feed, partially answers my question.
Andrew Barr, an expert in civil and structural engineering at the University of Sheffield, said that “the video doesn’t show any obvious structural deficiencies with the bridge, but it will not have been designed to survive a head-on collision with such a large vessel”.
He added:
Bridges in shipping lanes are sometimes designed with strong, stout piers, or additional protective structures around the piers to prevent ships from coming into contact with the bridge structure.
It doesn’t appear that the Key Bridge had either of these features, although it is also very likely that the size and design of the vessels passing under the bridge has changed considerably since it was completed in 1977. -
I suspect the problem is that the republicans just don't spend enough on maintaining infrastructure. It's like the Tories with public services. You can't just have tax cuts and expect things to magically maintain.
Short term thinking is the curse of all modern elected governments though. We used to build stuff thinking about the future. Climate change is coming and we're massively ill prepared. In fairness Biden seems to be gripping the bull by the horns somewhat."Plus he wore shorts like a total cunt" - Bob -
I think this is it, it's not the first American transport infrastructure to collapse and it won't be the last.
Actually mindboggled imagining the force a 300m godknowshowmuch tonne ship has. I don't think the bridge stood much of a chance.
Terrifying. -
The use of aerated concrete in schools was another stroke of short term genius. "From the people who brought you flammable cladding".
I wasn't criticising the bridge engineering earlier btw - just commenting on the forces in play that a bridge is built to deal with in order to just stand there.Holding the wrong end of the stick since 2009. -
From that quote I posted it would seem the answer would be to build protection at the point they started allowing bigger ships.
-
Having bridges anywhere near something of that heft is the original problem.
That ship had to go to/from a dock which had bridges between it and the sea.
It's something of very low liklihood but of huge impact. It's a red on any risk assessment. Building a bridge to withstand a knock like that doesn't seem feasible to me.Holding the wrong end of the stick since 2009. -
Vape prevention in schools. My lad says the boys toilets are full of kids huffing vapes and his school is in the posh part of town.

Sad that they are needed but it seems to be a big issue from what I can gather, far bigger than smoking generally was when I was at school.
Can't say I can get behind suspension or expulsion for it though. By this point these kids are obviously addicted, being in school would be far better than out of it for tackling that addiction. I'm sure it's not quite that simple in reality. -
I've been in scotland too long to know how things work down south anymore but schools here are very against expelling and rightly so. Suspension usually involves a couple of days at home and the rest spent at school away from the rest of the kids.
Never did get the expelling thing. It's just kicking the can down the road."Plus he wore shorts like a total cunt" - Bob -
Going back 20 odd years but I don't remember either being common.
Only remember one kid being expelled and he hardly turned up anyway. If he did it would be 10 minutes of mayhem before he got sent out of class.
Suspension was for very serious stuff. Normally someone who already had regular after school detentions and then did something big like having a fight or bringing drugs into school. -

Send messageIt’s 770 vape confiscations compared to 16 suspension and expulsions, so it doesn’t seem like a big proportion of vape interactions are leading to expulsions. I’d hope that suspension and expulsion wouldn’t be used disproportionately but I’d understand that indoor smoking can’t be allowed ad infinitum for the sake of the other kids."ERE's like Mr. Muscle, he loves the things he hates" -
The problem really are the vapes. Kids are way more addicted to nicotine then back in the day because they're so strong and they can have sneaky puffs anywhere. The days of a crafty Silk Cut at lunchtime are gone."Plus he wore shorts like a total cunt" - Bob

Has certainly been funny as a habitual smoker of maybe four or five cigs a day watch the chat around vaping go from this is better!!! why aren't you doing this too??? to oh wait maybe not to BAN THEM
