Designing a Wheel for the World’s Fastest Car
The Bloodhound SSC – supersonic car – built in the UK by a team of Formula 1 and aerospace experts, aims to inspire kids about Science, Technology, Engineering and Maths by reaching 1,000 mph. It is a battle with physics; a journey into the unknown. In this video Bloodhound SSC driver Andy Green talks about how Lockheed Martin UK designed the car’s wheels to withstand 10,000 RPM, pulling 50,000x the force of gravity.
