Transcript -- Improving the chassis

Formula 1 is the ultimate motor sport. It demands the highest level of skill from both drivers and the engineers behind the cars. So what are the secrets of good car design? How are Formula One cars engineered for maximum performance? This album takes a behind the scenes look at Red Bull Racing, a front-runner on the F1 grid. Using thrilling archive and expert testimony, the tracks explore how the techniques of Finite Element Analysis are used to optimize the performance of different elements of a Formula One racing car. The album is presented by Lara Mynors and features extensive contributions from Lewis Butler, Red Bull's senior structural analyst and Dr Ray Martin of the OU. The material is forms part of The Open University course T884 An introduction to Finite Element Analysis.
