While NASCAR keeps crash details confidential to protect drivers’ privacy, some drivers share the numbers from their crashes. But a single number doesn’t tell you everything about crash in the same way that finishing position doesn’t tell you the story of a driver’s entire race. […]
I looked through the blog and realized that IÂ haven’t really blogged about drafting. I’ve blogged about all the rules NASCAR’s enacted in the last couple of years to try to control drafting, but not drafting […]
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 […]
Track barriers originally were erected to keep cars separated from spectators. In addition to concrete walls to prevent the cars from driving off track, debris-spewing accidents necessitated fencing to contain airborne objects.
Catchfences should have the same properties as walls, but they can’t block the view. Chain link fence is a good compromise: It’s cheap, plentiful, easy to put up and surprisingly strong given its high visibility.
Chain-link fabric is an elastic metal mesh. It can give in two ways: gentle forces cause the mesh to deform. The diamonds stretch out of shape, but when the force is removed, the fabric springs back to its original shape. The fence can also deform by stretching the wires that make up the mesh. A large-enough force will break the wire entirely. […]
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 […]
Last time, I explained what the center of gravity (CG) is. This time, let’s look at why we care. […]
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 […]
