berkeman said:Can you give an example of what a Rube Goldberg machine is? I've heard the term before, but don't have a good definition in my head. Something like a complicated mechanism that doesn't really accomplish what it claims, or something like that?
A Rube Goldberg Machine is a complex contraption that performs a simple task in a convoluted and indirect way. It is named after American cartoonist Rube Goldberg who drew illustrations of such machines in the early 20th century.
People make Rube Goldberg Machines for a variety of reasons, including for fun, as a creative challenge, or as a way to learn about physics and engineering principles. Some also use them to demonstrate cause-and-effect relationships in a visually interesting way.
The key elements of a Rube Goldberg Machine are a series of simple machines, such as levers, pulleys, and inclined planes, connected together in a chain reaction. Other common elements include everyday objects like dominoes, balls, and ramps, as well as creative and humorous elements like toy trains, marbles, and even cats!
Building a Rube Goldberg Machine requires a combination of creativity, planning, and trial-and-error. It is important to start with a clear goal in mind and work backwards to figure out the sequence of events. It also helps to have a variety of materials and tools on hand to create the different elements of the machine.
Some tips for creating a successful Rube Goldberg Machine include making sure all the components are securely attached, using materials that are easily triggered and can withstand multiple uses, and incorporating elements that are visually interesting and entertaining. It is also important to test and troubleshoot the machine as you build it to ensure it works smoothly and achieves the desired result.
