How rollovers happen and what you can do to avoid one
http://consumerreports.org/cro/2012/02/rollover-101/index.htm
How rollovers happen. Given the right circumstances, any vehicle can roll
over. However, taller, narrower vehicles such as SUVs, pickups, and vans are
more susceptible than traditional cars are because they have a higher
center of gravity and thus are more top-heavy. Sideways forces that develop
when a vehicle rounds a curve shifts the center of gravity to one side,
which can have a dramatic effect on the vehicle's balance. The lateral
forces increase with speed and also with rapid changes of direction--for
example, when a driver makes too sharp a turn one way and then overcorrects
the other way. Those transitions can set up a pendulum effect, with larger
and larger swings and an eventual loss of control.
A single-vehicle rollover is usually not caused by a steering maneuver.
Instead, the vehicle usually has to "trip" on something, such as when it
swerves into a curb, pothole, or a soft roadside shoulder. The government
has estimated that 95 percent of rollovers result from trips. Some observers
say that number is too high. If a vehicle leans in such a way that a tire's
sidewall deforms and the wheel rim strikes the pavement and provokes a tip-
up, then the government counts that as a tripped rollover.
But Consumer Reports encountered that very phenomenon a few times during its
emergency-handling tests of SUVs in the 1980s and 1990s. We consider those
tip-ups to be untripped, because the vehicle essentially fell over itself on
a flat surface without encountering some obstruction. The distinction is
important because the supposed rarity of untripped rollovers has served as
an excuse for the government and the auto industry to play down rollover
risk and put the blame on the driver and road conditions rather than on the
vehicle. |

能在off road跑的车
在大马路上磕块石头 压个坑能干翻？
