Who is Rube Goldberg?

Rube Goldberg was an American cartoonist whose work mocked America’s fixation on technology. After receiving a degree from the University of California in 1904 he took a job designing sewer pipes for the San Francisco Sewer Department. A few months later he became a sportswriter and cartoonist for the San Francisco Chronicle and the San Francisco Bulletin. He also briefly worked for the New York Evening Mail, creating three long-running comic strips. His most popular drawings depicted complex gadgets that performed even the simplest tasks in convoluted, elaborate ways, known as Rube Goldberg machines. In 1948 he was awarded the Pulitzer Prize for his editorial cartoon, “Peace Today,” which conveyed a warning against atomic weapons.

2017 National High School Rube Goldberg Champion

The video below shows the winning Rube Goldberg machine from the National High School Rube Goldberg Championship in 2017. In this video you will see an elaborate machine performing the simple task of applying a Band-aid to a leaky faucet. This Rube Goldberg machine uses 70 steps/transfers of energy and 5 simple machines: wheel and axle, lever, pulley, inclined plane, and screw. Your Rube Goldberg machine must use at least 3 different simple machines and have a minimum of 10 transfers of energy or steps. Try your best to minimize your use of dominos.

What are Simple Machines?

A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. Usually the term refers to the six classical simple machines which were defined by Renaissance scientists: wheel and axle, screw, lever, incline plane, wedge, and pulley.
