BLOODHOUND SSC - The speed of sound

Thrust SSC is the only car in the world to have broken the sound barrier and reached Mach 1.02, that is 1.02 times the speed of sound at that location.

BLOODHOUND SSC has been designed to reach Mach 1.4,  a considerable step up from Thrust SSC. To calculate the Mach number the speed of sound must be measured, and you can visit the BLOODHOUND site to find out how to do this very easily using your computer.  You could then turn your skill at measuring the speed of sound into a project to achiieve a CREST award.

You might like to …

• Devise some ways of measuring the speed of sound, and carry them out
• Use the method on the BLOODHOUND site to investigate the speed of sound at different temperatures
• Use the method on the BLOODHOUND site to investigate the speed of sound in different materials
• Use the method on the BLOODHOUND site to measure wind speed by measuring the speed of sound in different directions.

Have you ever wondered how a speedometer works?

You might like to …

• devise a way of testing speedometers
• devise a way of measuring traffic speed without using radar
• design a speedometer for pedestrians or cyclists to use
• compare the accuracy of different pedometers
• Calibrate a bicycle speedometer.
