Bose/Berklee Field Trip

We went on a field trip to Berklee College of Music to learn about the physics of music. Pictures here. Videos, too!

Crash test with air bags

In this video, you can see that the airbag has good energy management. The airbag does work on the dummy, but it does it over a much greater distance than a steering wheel! That's why it exerts less force on the passenger.

The Smart Car is small, but it has good energy management!

Crash Test Dummies


KEYWORDS: General Motors Safety Technology Automobiles


To improve their smarts about auto safety improvements, engineers are turning towards dummies. Over the years, crash test dummies have become hi-tech safety test equipment that is helping safety engineers make vehicles safer.

Early crash test dummies were nothing more than sandbags in the shape of a human. The newest generation of crash test dummy costs about $200,000 and resembles a real person as closely as possible. The dummies are upholstered with soft vinyl to simulate skin and their steel framework behaves like a human in a crash.

State of the art electronics provide computer information that help engineers examine the dummy’s injuries and how to prevent them. Engineers then use the information to improve safety equipment for future cars. These safety devices are just one of the tools the automotive industry uses to keep vehicles as safe as possible.
