At the point of toppling the CoM is vertically above the downside wheel. If you estimate the relative mass of the engine and superstructure you can make a guess at how far above.AVGresponding wrote: ↑Sat Jan 03, 2026 1:13 amYeah it's quite visually disturbing to see, and somewhat counter-intuitive. It would be instructive to see where the actual centre of mass is.Zenith wrote: ↑Fri Jan 02, 2026 11:48 amThen maybe the slope was tilted at 28 degrees necessary for the test, but the bus was just on the verge of toppling and was at 35 degrees because the suspension was compressed as you suggested. Very impressive anyway.AVGresponding wrote: ↑Fri Jan 02, 2026 9:50 am You'd expect the angle on the bus to be larger in any case, due to compression of the suspension on the loaded side

The bus will be roughly symmetrical viewed end on. If you imagine the bus tilted in the other direction the CoM will be directly above the driver side wheel at the point of toppling. The point where the perpendiculars from the two wheels cross, I estimate to be slightly above the radiator cap. The CoM of the bus would be on that axis. That seems reasonable as a lot of the mass of the bus would be engine, chassis, transmission, wheels and seats below that point.

Re: Interesting findings on the internet
More modern buses will have an even lower centre of mass. The engine and gearbox package in particular is normally mounted very low down in the rear nowadays.

I had to share the hotel lift with the little guy on the left when in Shenzhen in August '24.
He/she/it could open the lift doors, select the floor to travel to and progress to the room # to deliver the online dinner order and signal the occupants their tucker was outside.
Darn smart are the Chinese.

But they appear to be tethered to the lift by their power leads? Or did they unplug themselves before delivery?

I'm surprised it doesn't have a "tip" jar. Seems everyone today feels they are entitled to a tip for just doing their basic job.

That would be asking for trouble. All sorts of unpleasant things could be put in it.
The thing strikes me as a gee whizz attraction. I doubt it adds significantly to the efficiency of the hotel.
