g-force

Hi,

I have been talking with a guy here at work about the amount of G-Force's that a car can take.

Here's the question:

A production car (any production car), with a good driver, with a perfect road(banked). How many G's will the car take. This question did not take into effect acceleration of bracking.

Please how many G's do you think that a production car can handle(max)

Downforce or lateral roadholding?

Max lateral G's depends on the car, and mostly has to do with the suspension and tires. Some of the better production cars pull around 0.90 - 1.0 lateral G's on the skid pad. A properly modified street-legal production car would get around 1.1 - 1.2 lateral G's.

Downforce has nothing to do with g-force.
Acceleration, decceleration (braking) or lateral (cornering)?

if you drove into a cement wall at 120mp/h you'd get about 100 G's but you'd be dead

a good street car will pull 1 g cornering. F1/indy cars are over 3g's. same with racing go carts

Downforce (vertical force) is in fact related to G-force. However, it is not usually as much of a consideration for road cars as the lateral and longitudinal forces.

Since we live in a 3-dimensional world, there are 3 G-force vectors. I'll try to relate them to a car...

Gx: Acceleration and braking
Gy: Flat Cornering
Gz: Bouncing over bumps

BTW, the reason that a car can corner better on a banked road is because some of the Gy force actually becomes a Gz force, which transfers some of the load from the tire tread to the springs and shocks. This is why your HotWheels can pull a loop even though they have crummy Mattel tires.

If you lower the above mentioned speed to 90 mph and then hit a bridge abuttment (head on), you would experience serious G- Force. The type that causes your seatbelts to cut you open. they also deliver neck snapping jolts. I can't believe i walked away.

He did sustain a minor head injury resulting in mild retardation.

hey i hit a BIG tree with an impact speed of 100mph, i was doing 130mph and the skidding slowed my impact speed to 100mph, talk about some G's, and a vin plate going through my eyelid, and some really nice seat belts marks

there's no definite answer to ur question
it really depends on ur tire condition also

but Lateral acceleration is the ratio of centrifugal force to the car's weight
