WHAT WE SEE
This is a picture taken from a video. The video is of Ryan Hunter-Reay driving the Barber Motorsport Track in his Indy Car. When Joe Autera, CEO of Vehicle Dynamics Institute, and I (Tony Scotti) looked at the posted video, this is what we see.
The video shows the driver maneuvering through a corner at 148 MPH and applying 3.2 G’s to the CG of the race car. At that moment; if the driver weights 160 pounds, there are 512 pounds pushing on his body. From the Verizon Indy car website, a Dallara Indy car weights approximately 1580 lbs. Also at that moment, there are 5056 lbs pushing on the Dallara’s Center of Gravity. Also, in case you are interested, the vehicle is moving at the rate of 217.56 Feet in a Second, and at 3.2 G’s and 148 MPH, the driver is moving through a 456 Ft radius. Another note of interest – if, at that moment, Ryan turned the steering wheel one second later there is a strong chance that he would apply approximately 6 G’s to the center of gravity of the vehicle which would create a large amount of excitement.
