It’s amazing how flimsy the best builder’s work can become under the right circumstances. The video above contains some examples of components you’d think of as extremely rigid, like the carbon fiber bodywork of a MotoGP race bike, turning into a floppy mess at speed. Components are designed to be just as strong as necessary with very low safety margins, and some of the flexion you can see in these clips is enough to make one nervous about the engineer’s grasp of mathematics.
Weirdly, the bending and oscillating throughout the video, along with the worrisome deflection in some of the tires and, my favorite, gouts of flame from a Bathurst racer’s exhaust at the video’s end, are all normal operating conditions. It’s remarkable that what you see here is not failures, breakages, or crashes, but just days in the lives of highly-stressed machinery.
