Others pass out at 3 g , he says. Pilots can boost their natural g tolerance by training inside centrifuges, like the one Qinetiq has in Farnborough in Hampshire.
They learn to tense their leg and abdominal muscles to push blood to the upper body, and to breathe in a special way, straining hard as if defecating when constipated, to raise blood pressure. The greatest vertical force anyone has withstood is Flanagan Gray …. Existing subscribers, please log in with your email address to link your account access.
Paid quarterly. On an airplane, the wings provide lift. A Champ Car has spoilers that are like upside-down wings, providing the opposite of lift: downforce. The downforce keeps the car glued to the track with a downward pressure provided by the front and rear wings, as well as by the body itself. The amount of downforce is amazing -- once the car is traveling at mph kph , there is enough downforce on the car that it could actually adhere itself to the ceiling of a tunnel and drive upside down!
In a street-course race, the aerodynamics have enough suction to actually lift manhole covers -- before the race, all of the manhole covers are welded down to prevent this from happening!
Between the downforce and the G-forces, well over four times the weight of the car holds the tires to the track when it goes around one of those degree banked turns at mph. Drivers take an enormous amount of punishment on a track like this. This level of acceleration is higher than most people ever experience. Even the space shuttle only develops 3 Gs when it takes off.
What's even more amazing is how long these drivers tolerate this kind of force. The Texas Motor Speedway is 1. It only takes about 4 seconds to make it down the back stretch before the next turn and another 6. If the planned mile km race had taken place, the drivers would have gone back and forth between 5 and nearly zero Gs a total of times. Sign up for our Newsletter! Mobile Newsletter banner close.

On the other hand, for a box truck carrying paper towels, a lower sensitivity might be sufficient. If we look at the three harsh driving rules, we can do some simple calculations to find out how fast a driver would need to take a corner or accelerate from a stop sign to break these rules.
The harsh acceleration and harsh braking rules are really the same thing and measure how quickly you are speeding up or slowing down. The least sensitive setting in the default rule for acceleration is 0. To get a better understanding of linear acceleration and g-forces, check out this handy Acceleration Calculator.
Harsh cornering is a little trickier to both calculate and grasp intuitively. Any time you change velocity you are undergoing an acceleration. When you are turning a corner, this acceleration is 90 degrees from the direction you are traveling, regardless of how tight a turn you are making. Think about spinning a weight on the end of a string. You are always pulling the weight towards your hand but it never gets any closer.
So how do we measure this? To determine the acceleration you experience in a corner, all we need is the radius of the corner and your speed. I measured the radius of a normal right turn at an intersection of two four-lane roads and found it to be about 17 metres. If you want to play with the number yourself, you can find a centrifugal force calculator here for accelerations in a corner. Distracted driving facts: Common causes and solutions.
