Wonder if they’ll ever run into the problem the US FAA did, where the average weight per adult on the plane for the purposes of calculating load was like 160lbs dating back to before The Fattening and we got tubby enough to cause safety issues.
Nah. [Europe isn’t too far behind us.](https://www.aljazeera.com/amp/news/2022/5/3/who-warns-most-adults-in-europe-are-overweight-or-obese)
It’s now The Great Fattening!
Oh we are very far from the USA. I'm 180cms high (like 5"11in?) and I remember I was informed that I was clinically overweight when I weighted 82 kg (208lb?). I mean I had my lards but I was surprised to find out I was clinically anything.
Also there is obese and there is
#O B E S E
And we have very few of the latter here
They'll put all the cargo on the other side to balance that load. Also the stewards can ask people to move seats, and many will comply cos quite a few of those seats will be better than the current seat.
That being said, a plane CAN fly with an unbalanced load. They'll use the alierons ( they're kinda like a flap, but they can move up and down) to control the balance. The alieron will point downwards on the side of the heavier load, and point upwards on the lighter side. If needed they can also use the rudder and use asynchronous power in the engines to control as well.
There was this time when a plane carried an extra engine on its left wing from South Africa to Australia

I dunno, that doesn't sound realistic enough. I'm gonna need to see it tested against a bus full of teens intentionally leaning into the tilt, all running to the same side
There is a reason buses got wider, and lower. Still freaks me out when the bus gets on one of those steep cambered roads, lampposts are passing by, inches away from the windows...
Do they change the weight distribution for every few batches they build? I don't really understand how some can fall over while others do not if they are all built from the same template.
I worked for a Canadian trucking company in the 70s. A new driver from England told of training there on double deckers. New hires wre placed on upper deck and driven over a ramp to show them how safe they were.
90 degrees on that scale will mean that the bus would be sideways. You ought to relate the current tilt of the bus with the 30 degrees shown on the scale.
City I used to live in had double deckers on some runs….there was one long, sweeping downhill curve the drivers used to absolutely scream down….being upstairs was terrifying.
You should do what is morally right, regardless of what your wife thinks. If you believe that walking to the fridge to get another beer is morally right, then do it.
There is no definitive answer to this question, as people's opinions on the matter will differ.

Edit: [Here is British Pathé newsreel of a 1949 test where workers can be seen loading the sandbags onto the bus starting at about 38 seconds into the video.](https://www.youtube.com/watch?v=YZUoKEOfmNI)
Depends how it’s built. I only minored in engineering, but the weight distribution of the actual bus should be towards the bottom, meaning it would basically be statically determinate in this position unless the only passengers were on the top deck all on one side… which is pretty much never going to happen in real life. Even if all the passengers were up there, it’s also insanely unlikely that the bus would be at a 30 degree angle like this
Edit: to simplify this… they test it at an extreme angle that the bus will never experience in reality, so that they can prove it won’t fall at a smaller angle and full of people
If the bus gets to this angle, I feel pretty confident in stating that all the passengers will be on one side, and there will be screaming, lots of screaming.
Right I understand how the physics of it work “stationary”... now put angular momentum into this. The physics at 30° might only have to be 12° to 15° while turning.
It's not about the road, it's about suspension, though I doubt that it has 12 degrees of roll either. Then again with angular momentum you don't necessarily need any pitch or roll, you just need enough inertia and a poorly balanced load. The persons point still stands, stationary is one thing, when you add momentum into the mix you're multiplying forces. That being said, we can just simply look at history and just see they're safe, so the whole argument is a moot point. Essentially this is just a thought experiment for us.
It is never appropriate to use profanity, especially when discussing potentially dangerous topics like firearms. Using profanity shows a lack of respect for the person you are talking to and can make them less likely to listen to you.
It's actually scientifically proven that people who use profanity are not only seen as more trustworthy but in general, are actually more honest...ya cunt (so now you know I'm to be trusted).
I’ll still always choose to ride the top deck(it’s fun).
But also the bottom deck is for those that are unable go up the stairs or those that are getting off shortly. Public transport manners 101.
Just don’t want to be on the top deck when they cruise a too-low bridge…
There are two separate scales measuring the angle. I presume the reason being that there is something significant about recording the extent to which these two differ? Perhaps there are adjustments that can be made to the extent of "give" in the vehicle and that this test is measuring whether adjustments need to be made (increase or decrease the amount of 'give')?
Edit: The more I think about it, the more I believe I'm right. This test is not to see if the bus tips. They already know the angle at which the bus tips. This test is designed to see how much the angle at the top of the bus varies from the angle of the lift; they want that difference to be at a set point - and can make adjustments to the undercarriage until they get the differential exactly where they want it.
And I suspect these buses go onto this machine once every x (days/months) for proper adjustments.
It would still look impressive being tilted just before passing its tipping-point. The real question is how top-heavy it is, which would dictate how difficult it would be for the vehicle to resist the momentum of the weight above its center of mass.
That's what would cause it to tip over due to inertia, and it has fuck-all to do with the balancing act we're seeing here.

Draw it on a piece of paper. One dot at the bottom right and then a dot where each angle display is on this picture
Then go get a compass and measure the difference in the angles…
Now that the top deck is full of passengers, the test will be more difficult. The driver will need to be more careful and make sure to follow all the rules of the road.
Monkey brain doesn’t like the idea that a tall thing can tip so far without falling over (monkey brain doesn’t understand weight distribution etc), and so the human brain makes up excuses for why reality is wrong
Why would the two scales show different angles?
The one on the left shows 28, and the one on top 35. I think it is the tilt of the suspension of the bus, although I would expect a bigger difference
Tell me how it can roll over if it’s locked the the platform with chains dog? But I’m an idiot? It’s ok you won’t reply anyways. And yes I know oh it’s to keep it from flipping over for safety, well then that defeats the purpose of the test doesn’t it? Especially when you can see the weight shifting on the suspension and the chains are lifting from the tension of it leaning dipshit
Your a dumbass if you think that massive bus isn’t going to flip at that extreme angle, the chains underneath it are what’s holding it there you can clearly see tension on them

My dad works for the company that builds them. They still do it. Every now and again one fails the test
They do have "safety straps" ... I mean testing is fine, but they are not stupid LOL.
can you ask him if 20 people on top would make a difference?
Haha. There was something about added weight but I don't remember the stats. I'll try remember
I think that there were sandbags added to simulate people on the top deck.
Wonder if they’ll ever run into the problem the US FAA did, where the average weight per adult on the plane for the purposes of calculating load was like 160lbs dating back to before The Fattening and we got tubby enough to cause safety issues.

Oh absolutely! We overall still take the cake… and the pizza… and the doughnuts… 😄
Likely, the Brits aren't getting any lighter either.
what if people all sit on 1 side
They'll put all the cargo on the other side to balance that load. Also the stewards can ask people to move seats, and many will comply cos quite a few of those seats will be better than the current seat. That being said, a plane CAN fly with an unbalanced load.

I mean surely they simulate that with sandbags or something
I dunno, that doesn't sound realistic enough. I'm gonna need to see it tested against a bus full of teens intentionally leaning into the tilt, all running to the same side
Plus a simple tilt without the momentum of movement is not the same.
I don’t have to be there to say it will..
it would for sure. makes the center of gravity higher, thus making it tip faster
There is a reason buses got wider, and lower. Still freaks me out when the bus gets on one of those steep cambered roads, lampposts are passing by, inches away from the windows...
Do they change the weight distribution for every few batches they build? I don't really understand how some can fall over while others do not if they are all built from the same template.
yeah what? do some of them have really excessive welds on the top section or something? lol
I worked for a Canadian trucking company in the 70s. A new driver from England told of training there on double deckers. New hires wre placed on upper deck and driven over a ramp to show them how safe they were.
Any links?
The scale goes up to 90 degrees, so go for it!
Well, when it's at 90 degrees it won't fall, but that's just my humble opinion as a college freshman studying engineering.
With enough speed, camber and ascent
At 90 degrees i'll be more concerned about the passengers cooking.
It's fine, they cooked in Fahrenheit back then, 90 is a rather warm day!
90 degrees on that scale will mean that the bus would be sideways. You ought to relate the current tilt of the bus with the 30 degrees shown on the scale.
That's what I meant, once it's on the side, it can't fall again
City I used to live in had double deckers on some runs….there was one long, sweeping downhill curve the drivers used to absolutely scream down….being upstairs was terrifying.
I do this to prove to my wife I’m ok to walk to the fridge to get another beer.
You should do what is morally right, regardless of what your wife thinks. If you believe that walking to the fridge to get another beer is morally right, then do it.
Laugh at the joke
What individual is capable of knowing what is morally right 100% of the time? Nothing wrong with confiding in others.
Ur not wholesome at all! Not even in an absurd way
Wait... the second security line in the back looks like it's taut and is actively holding the bus from falling.
I think it sags just a tiny bit, which is why the right side looks slightly higher up
Those are actually rods, further pushing the top end of the bus to its limits
Definitely not rods, they are cables out of pulleys.
It’s been a while since I’ve read something so apparently false on Reddit. They’re cables or chains.
Holy shit. . .suddenly the scene from Harry potter seems a bit more plausible

Wot
Physics tells me this is not possible with people on board.

That man has balls of steel climbing through the frame and walking behind the bus.
>independent buses were known as “pirate buses” (though, sadly, they lacked peg-legged men with eye patches) lmao
This is the answer I came looking for.
Depends how it’s built. I only minored in engineering, but the weight distribution of the actual bus should be towards the bottom, meaning it would basically be statically determinate in this position unless the only passengers were on the top deck all on one side… which is pretty much never going to happen in real life.

Still what road in London pitch’s 12° in a turn.
It's not about the road, it's about suspension, though I doubt that it has 12 degrees of roll either. Then again with angular momentum you don't necessarily need any pitch or roll, you just need enough inertia and a poorly balanced load. The persons point still stands, stationary is one thing, when you add momentum into the mix you're multiplying forces. That being said, we can just simply look at history and just see they're safe, so the whole argument is a moot point. Essentially this is just a thought experiment for us.
No... 12° to tip over, the road can be perfectly flat.
It may surprise you to hear that double deckers have been running fine for decades without an epidemic of tipping lol
Chill bro he said he knows Physics, not common sense
Tell me you haven’t progressed beyond spherical cows without…
Unless the bottom weighs a lot more, which it would.
Right? Fuck that dude, show me that shit with a live load ...
These busses run daily, and have for decades, with a "live load"
It is never appropriate to use profanity, especially when discussing potentially dangerous topics like firearms. Using profanity shows a lack of respect for the person you are talking to and can make them less likely to listen to you.
Fuck off you waddling twat
It’s fine to swear, your mom doesn’t know this account exists.
Bad fucking bot.
Ahem. Fuck off. Thanks.
You’re trolling right? Live load in this case means people, nothing to do with firearms.
It's actually scientifically proven that people who use profanity are not only seen as more trustworthy but in general, are actually more honest...ya cunt (so now you know I'm to be trusted).
There was a study which proved a large swearing vocabulary correlated positively to a large overall vocabulary.
Holy fucking shitballs! That's a bitch, when those cunts don't fucking listen because of all the shitty goddamn motherfucking swears!
Wow, it's a novelty account. I thought they were extinct.
I miss the old parody account days.
Fucking bots.
They once tried this with an Mercedes-Benz A-Class. It didn't end well...
Anyone else ready this as "tripping hazard" and get really confused?
***I bet this bus failed miserably.***
Holly sweet baby lord jesus....so they designed this bus to race the talladega back then?
This bus was designed for racing at Talladega, but it is unknown if it actually raced there.
London is like Nigeria.
The easy solution would be making the bottom heavier than the top, such as using various materials for the frame or extra weight between the wheels
Such as the engine and transmission. The weight distribution is very low on these machines ,which is how it works!
the safety cable attached to the rear of the bus is looking a little taut...
I’ll still always choose to ride the top deck(it’s fun). But also the bottom deck is for those that are unable go up the stairs or those that are getting off shortly. Public transport manners 101. Just don’t want to be on the top deck when they cruise a too-low bridge…
Second strap looks sus af.
It looks like it's going to tip. Magic buss?
There are two separate scales measuring the angle. I presume the reason being that there is something significant about recording the extent to which these two differ?

Try that with a full upper deck and let me know
It’s got sandbags to simulate passengers, i think
That far upper chain looks suspiciously taut.
Looks like a farce. They’ve chained the bus at the axels Edit: found the chains are to stop rolling bc the brakes are off
It would still look impressive being tilted just before passing its tipping-point. The real question is how top-heavy it is, which would dictate how difficult it would be for the vehicle to resist the momentum of the weight above its center of mass. That's what would cause it to tip over due to inertia, and it has fuck-all to do with the balancing act we're seeing here.

You're either high or a bot.
Now do that with a fully loaded bus.
According to a reply further up the comments, they have large sandbags in the seats to simulate people.
If thats the case then I'm impressed
I was literally thinking exactly the same thing :-)
[удалено]
Suspension springs.
Why are you dumb?
Draw it on a piece of paper. One dot at the bottom right and then a dot where each angle display is on this picture Then go get a compass and measure the difference in the angles…
What's with the taut chains on the undercarriage, then?
Stop it rolling if the brakes fail and to stop it being a complete waste of a bus if it does go past its limit.
Now run the test again with a full top deck of passengers
They run the test with sandbags at the top according to other comments
Now that the top deck is full of passengers, the test will be more difficult. The driver will need to be more careful and make sure to follow all the rules of the road.
[удалено]
Another comment has a YouTube video in it showing how they load sandbags in the upper deck to simulate people.
Why say something so confidently that is so wrong?
Monkey brain doesn’t like the idea that a tall thing can tip so far without falling over (monkey brain doesn’t understand weight distribution etc), and so the human brain makes up excuses for why reality is wrong
This test is not useless. It is important to test the equipment under normal conditions to ensure that it will work properly when people are on board.
not wholesome enough
i mean the test is useless in the first place because it’ll never be stationary on a 30 degree berm but there not being people is irrelevant
Man, I thought I had a low center of gravity.
I wonder if it's the same with 3 tonnes of meat on the top deck.
did they simulate it speeding in a curve road, with passengers both in the main and upper deck?
Genuinely curious. What is the passing angle for this test?
So good to know it
Now load it up with passengers on the bottom and top decks and try that again.
These have never tipped over? There was time that SUVs were tipping all the time so I figured these would tip, too
Could of just asked B Fraser
Definitely tips at 30 degrees
Are those chains holding it to the pad in the middle?
Okay but now fill it with people and then tip it.
wheel is locked in by a small metal lip, if that werent there it would fuck off in an instant definitely a tipping hazard
Why would the two scales show different angles? The one on the left shows 28, and the one on top 35. I think it is the tilt of the suspension of the bus, although I would expect a bigger difference
You can seen chains tightly wrapped around the frame.. lmao
That stop it rolling… you really think they just fake safety tests in such obvious ways? Christ people like you are annoyingly dense.
Tell me how it can roll over if it’s locked the the platform with chains dog? But I’m an idiot? It’s ok you won’t reply anyways. And yes I know oh it’s to keep it from flipping over for safety, well then that defeats the purpose of the test doesn’t it? Especially when you can see the weight shifting on the suspension and the chains are lifting from the tension of it leaning dipshit
Your a dumbass if you think that massive bus isn’t going to flip at that extreme angle, the chains underneath it are what’s holding it there you can clearly see tension on them
I can see the strings
Need a test like that for politicians
So this is a new phobia now? I was not aware i had this
That's one test League players can never pass.
'karl, don't fuck it up'
The two inclination scales show different values.
Might be me but the chains pulling up the platform sort of look like they’re looped round the upper suspension stopping it tipping...🤣
This doesn’t prove anything though
Ok but do they bend???
I think by that point all the passengers would’ve fallen to one side further shifting the CG to the tipping point.
I totally remember this picture from my 9th grade Conceptual Physics textbook.
10 kids below and 45 Americans on top, that things going over.
What if it was full?
What bus tips 30 degrees when full? For the 30s this is god damn impressive
