How is a NASCAR Driver at Bristol like an Astronaut?
The Unique Challenges of Bristol Many drivers will tell you that, despite not having the highest speeds or a unique shape, or a long race time, Bristol is one of the most exhausting stops on the schedule. Laps take about 15 seconds, with about 60% of each lap being turns. […]
Turning at Bristol: A Weighty Matter
A lot of drivers cite Bristol as one of their favorite tracks. It’s a great exhibit for the argument that racing is more than just pure speed. High banks (which we know mean speed!) and a short track, which means tight racing. But a lot of drivers will tell you that Bristol is one of the most exhausting, physically demanding tracks on the circuit. Add to that the inherent stress of short-track racing, where 43 cars are operating in a limited (half-mile) track.
Racing without Friction
Daytona is an enormous, sweeping track. Two-and-a-half miles, 31-degree banking and corner radii of a thousand feet. The infield by itself is 180 acres. If you’ve ever been there (or Talladega), it really does take your breath away when you first enter. Now, bigger tracks (or rather, tracks with bigger turns) automatically […]
Sounds like an energy drink, right? Listening to Kyle Busch’s press conference Wednesday was alternately fascinating and cringe-worthy. The fact that he remembers so much about the crash is amazing – it will be a great boon to the safety people who probably will use this as a case study […]
Center of Gravity, Part II
Last time, I explained what the center of gravity (CG) is. This time, let’s look at why we care.
Turning, G-Forces and Banked Tracks.
Dover is a fascinating track – twenty-four degrees of banking, but only a mile in length. A student approached me with a question: Higher-banked tracks generate higher centripetal forces – so why doesn’t the track banking appear in the equation for centripetal force? I’ve talked about centripetal forces in detail […]
