There is a small hill on the way to school on the road.. It's like a bridge, but its a little bump, quite steep actually, but small.
However, I was thinking at that time, whether it is possible for a long vehicle, such as a lorry or bus to go over that hill?

Where I am from this is called getting high-centered. I.E., the center of the vehicle gets stuck on the higher ground.
The way getting high-centered occurs is this: the clearance of the vehicle is less than the height of the obstacle. When the momentum of the car (bus) carries it onto the hill but isn't enough to keep it going over this obstruction, you are stuck.
I have been in this situation several times when I am out in the countryside on some of the bad roads. It also occurs on sandy roads when the sand builds up in the middle of the road.
If your lucky, the obstruction is made of dirt or sand. Then you need to get out, get a shovel and dig your way out. I still have my shovel here in the flat I occupy.
If this sad event happens and you are on solid rock, expect a large repair bill. You tear up the underside of your car, truck, bus or wheelchair....

So it is possible for a bus to get stuck on a little hill such as that?

Why do you want to stop a bus? There is somone inside you want to meet? [;)]
-
I don't want to stop a bus.. I was worried that it'd crash or get stuck if a bus goes over the same hill I go over on my way to school!
-
I've seen it happen to cars...
-
Nasty!! Wasn't a nice sight, eh?
-
So it is possible for a bus to get stuck on a little hill such as that?
Yes, it is possible and this is what I was trying to explain but had to leave for a concert - no, not punk rock or anyting in that vein - went to hear Bach's Magnificat and Schubert's A Minor Mass
But that does not answer your questin
YES, IT IS POSSIBLE !

Hey this is the Rig My husband drove for years notice the placement of all the wheels, this prevents High centering in some cases, but he always said if the space between the wheels was too far and the raised area was taller the the trailer floor bottom it would be a problem!

OK, I might as well add
"It was a foggy day
On the sixth of May
In a Scammell hauling bricks;
It was just crackin' dawn
And I started to yawn
'Cause I couldn't find any nice chicks.
I tried Newport Pagnell, Toddington,
And even Watford Gap.
But after so many eggs, chips, sausage and beans
What I really needed was a nap.
It's a lonely life truck-driving:
But it's better than a bike.
'Cause when you're up in the cab
You're the king of the road
And it's dead romantic, like?
Then I remembered me two-way radio,
So I started feelin' better:
And I thought "I'll start a convoy:
You know, just like that American feller!"
[Choir]
Thus began the saga
Of the M1 motorway
The biggest blooming convoy
Outside the USA
Why not join our line-up?
It's completely free.
All you need is transport
And a current MOT…
Convoy…
[SS] "Hello this is Super Scouse calling: anyone out there come on."
[PC] "Er, hello, hello, this is Plastic Chicken, go on."
[SS] "That's come on. What's your load, Plastic Chicken?"
[PC] "Well, it would have been quick-drying cement, but the rain got in… do you know anybody that wants to buy a three-ton brick?"
[SS] "Aargh!"
[SS]
So there we were, the two of us,
At the start of something big
There was Plastic Chicken with his brick on wheels
And me in my big rig.
With every junction that we passed
Others would tag on
There was even a London Transport bus
[WIA] "Hey, that's a nice wagon!"
[SS]
It certainly was an impressive site
To see us on the road
There was vehicles of every shape and size
We certainly had grown!
Suddenly there was this commotion
There was a circus, and a fair
There was an animal acrobatic act:
[PC] "Oh look, a bear in the air!"
[Choir]
You're listening to the saga
Of the M1 motorway
The biggest blooming convoy
Outside the USA.
We're halfway through our story
But please don't go away
Here comes Spaghetti Junction
[PC] "We could be here all day!"
[Choir] Convoy…
[PC] "Hello, Plastic Chicken to Super Scouse, get off, er I mean come in, er, do I have to say this every time?"
[SS] "Yeah! Have you seen any fuzz-boxes? That's slang for police cars."
[PC] "Jackanory, Super Scouse: that's slang for 'no'."
[SS] "That's negatory, you berk."
[PC] "Oh…"
[PCV] "Say, is this a private convoy, or can anyone join in?"
[AT] "Watch your wheels, our kid."
[PCV] "Would you believe it, a camper? <giggle>"
[SS]
Spaghetti Junction was comin' up
So we were bound to lose a few
And sure enough, the fork lift truck
Disappeared heading off towards Crewe.
The combine harvester shred a wheel
And the driver lost control
And a mobile DJ crashed his van
[Blues] "So he ain't gonna play no soul, 10-4"
[Choir]
And so we end our story
Of the M1 motorway
Of the biggest blooming convoy
Outside the USA
This record is good value
As you can plainly see
It's labelled as a tax disc
So it's a felony…
Convoy…
[Choir repeats "Convoy…" behind the remaining dialogue.]
[PC] "Plastic Chicken to Super Scouse: there's a big black limo coming up behind me..."
[SS] "Well, what about it?"
[PC] "Well it's got a flag on the front and a funny number plate - HRH1."
[SS] "Oh, mercy sakes, good buddy, better give her the front door and wave her on, like."
[PC] "Will do, Super Scouse, I've waved her on: ooh look, she's waving back."
[SS] "Plastic chicken, er, do you want to stick it in behind that suicide jockey?"
[PC] "What's a suicide jockey?"
[SS, as JS] "As it happens owzabout ooohiiieeoooh" [Explosion]
[SS] "Er, Plastic Chicken, don't you think you better change gear for this hill?"
[PC] "Er, What's wrong with the gear I've got on, I mean doesn't it look right?"
[PC] "Change gear, ram the floor, change the gear, what are you talking about? You don't want to drive a truck, do yer?"

Yup, even that could still get stuck.. There are tiny gaps in between the wheels still.. *Sigh*
-
What are the measurements or dimensions of this hill?
-
Well.................... I'd say about 2.5m wide and 0.8m tall.. ish..
-
Well.................... I'd say about 2.5m wide and 0.8m tall.. ish..
Sounds like it is scarcely more than a speed bump.
-
Well.. about 1m tall and 2 metres wide.. its quite a radical jump..
-
Sounds like it is scarcely more than a speed bump.
well i thought you had it, George. But, Seany has gone and changed the measurements of the "hill". With the new measurements, i would say that the bus will not make it and therefore get stuck.
1m tall, 2m wide. That is a semi-circle, and i don't think the bus will get over it. It would make a good jump on a bicycle though.
-
LOL what is the conversion to those measurements It sounds like a heck of a hill!
-
well... if i'm not mistaken, there are a hundred centimeters in a meter...
-
that's just guessing. the metric system confuses me, but centi means a hundred... so...
-
LOL how much is a meter.. LO I hate math and numbers LOL I want feet and inches!! LOL
-
i don't know. lol. it's a hundred centimeters. do you have a ruler? we have centimeters on our rulers!
-
I never paid any attention and don't have a ruler how about a eyeball guess!
-
well... i think my pinky finger is a centimeter or so across. however, i have the hands of an eight year old
-
tiny tiny girl you is!
Eh forget it LOL LOL I will never get it figured my brain has malfunctioned somewhere between the brussel sprouts the conversion of the metric system and the pms.. LOL I love it makes me smile! LOL
-
this is getting to be a strange night. if anyone can give us a better conversion it would be appreciated!
-
Where is everyone anyway!
-
cuz i tried... but nobody can see my little finger
-
Your little finger must be tiny if your ring finger is a 4 LOL!
-
LOL!!
1m = 3 ft 4 inches
2m = 6 ft 8 inches
-
YAYYYYYYYYYYY!!!!!!! SEANY... LOL you are so funny! LOL hee hee hee! LOL
Now I have an idea!
-
lol. i just figured it out with a ruler. now that i understand it, that is a substantial hill. i don't think a bus would fit
-
Sounds like my front garden wall. Most buses are only about 12 inches off the ground so i think they would need to find another route.
-
Yep.. I thought that the hill was quite a...... large jump
-
Sounds like a rough spot in the road for sure!
