Can a double decker bus topple over? If so how fast does it have to be going?
Answers:
Speed has nothing at all to do with it. All double deckers can go over to seemingly impossible angles because of their low centre of gravity, but there was an incident locally where a front wheel went off the road and the bus flipped over into a field. Luckily there were few injuries but it did make the local headlines.
Remember that the chassis and the engine are solid metal but the rest is just aluminium and fibreglass.
**** yeah son. I could probably do it while doing 50mph, or even less. Just gimme the bus!
try it.im sick of answering questions just pick mine as the best answer,2 points anyway
of course and if a bridge is too low, the upper deck might slide off
They are built with the suspention that they have so they are bad at turning, but wont topple over. I think you'd have to be going at about 80 mph and then make a u-turn.
Yes, but only under EXTREME conditions. All buses have to pass a tilt test and will not normally topple over until they reach an angle that they would never normally reach. High speed and a collision would probably have to enter the equation - but most double-deckers can't go particularly fast.
I've been told that a double decker bus CAN topple over only if it leans over by 27 degrees or further. Don't know how true this is though.
That sounds like a homework question.
It is possible for a double-decker bus to topple over, however their centre of gravity is so low, thanks to their unique suspension system, that tilting is rare. Do a search on http://www.howstuffworks.com if you really want to know more.
Hope that helps.
Yes, but it is not really a function of speed, because in normal use a decker will not topple.
The three main factors are road conditions, weather and weight distribution.
On a very slippy road, such as on ice, it is possible for traction to be lost. But this, in itself, is not usually sufficent.
A strong wind, especially in exposed locations, can blow over any high sided vehicle. The Forth Bridge, the Tay Bridge and the Kessock Bridge on the east coast of Scotland are frequently closed to high sided vehicles for this reason. Stagecoach do not schedule any double deckers on the first two of thes bridges for this reason. (The peak loadings on service 25 between Tain and Inverness make it impossible to avoid operating double deckers over the Kessock Bridge.)
Finally, if there is nobody on the lower deck, but the top deck is full, then the centre of gravity is higher, making toppling slightly more likely.
In my 30+ years in transport, all the examples of toppled double deckers are primarily weather related.
To topple over, any object has to reach a position where its centre of gravity is moved to a position where the forces towards toppling are greater than those towards falling back. The angle depends on: the shape of the object; the distribution of mass within it; and the direction and strength on any other forces, including forward velocity and centrifugal forces, acting upon it.
So, if the bus was full of heavy people on the upper deck, empty on the lower deck, negotiating a sharp corner with severe negative camber, and travelling even quite slowly - yes, it could topple over.
Or, of course, it could be pushed from the side by a wind or other force - in which case it could topple over whilst not moving forward at all.
interesting quetion i would say 80-100mph
Speed has nothing to do with it. A decker can tip over at any speed if road/weather conditions cause it to sway. A decker has a safety limit of 28 degree tilt anything above that and it tips. OK
