Did someone turn off the gravity? I make this the 3rd this week.

Must be the supermoon….lol

Nope, gravity played a big part ….. mainly when the centre of gravity of the vehicle changed in relation to the base supports (wheels).

When the horizontal area of the wheelbase is reduced as it hits the slope of the ditch, the CoG will eventually be outside of the stability rectangle and will therefore roll over.

;-)

Hope they were/are all OK.

Gus is that something like …if the ID exceeds the OD the hole will be on the outside?

Actually it is gravity which keeps the vehicle *glued* to the road – the tires are in contact with it! Turn off gravity and things will keep going in a straight line as if they are floating – we all have seen video from the ISS. So billyinpg is not all that incorrect! ;-)

Keep up the research though, gus!

What’s a “mile”? :)

Texting? Drunk? The freaking road looks pretty straight in the photo.

1600 metres or so axman! ;)

Okay, a simple little search on CoG got me this web page. I then copied the address and pasted it here … beats trying to tyope it out long hand anyday……. ;-)

I understand that physics is not an average Canadian’s strong point. That may be a reason why the first page that showed up is one from the UK. ;-)

Just be glad that I decided I had better not introduce the role angular acceleration plays in the shifting of the CoG towards the outside of the vehicle …. that would blow everyone’s mind …. LOL

Blew a tire, lost control, went into the ditch.

Bearing shot on a wheel; wheel came off, lost control, went into the ditch ….

Come on, help me out with the scenarios that might be appropriate for a vehicle that is an older model truck.

PG … it is not research I did. It is part of an industrial road defensive driving course I am involved with.

I know, CoG is not a topic in standard driving courses accredited by ICBC. Yet virtually all vehicles using industrial roads have high centres of gravity, and when some of the crew cabs have ATV’s loaded in the back they are even more vulnerable to roll over when angular acceleration is added going into a curve, especially if it is not superelevated.

To put in redneck parlance….Dolly Parton will tip over a lot easier than Emmylou Harris ;)

You’re a real class act dodo!

“It is part of an industrial road defensive driving course I am involved with.”

A lot of industrial road truck drivers should sign up for that one, especially since they also use the common everyday variety roads that we normally drive on!

Come to think of it, everybody should practice defensive driving because it is a lot safer than the offensive driving one is confronted with daily!

A mile is 1760 yards, or 63,360 inches.

Interesting that the Americans (Our biggest trading partner) never went to the metric system. How do they manage to survive under the old system??

We were given to understand that metric is the way of the future. Some 20 years later the docile Canadians are doing what they are told and using the metric system on a daily basis, while the Americans basically told the rest of the world to go to hell. Hmmmmm.

Ever notice that all rail cars are not in metric, or at the very minimum both.

Is to-day a slow news day???? Has it been a slow news week?? Just askin,.
