Just finished reading through MakerMechanics' deep dive on the meaning of friction in mechanical engineering, and it's got me thinking about how often we treat friction as just a problem to be solved, rather than something that can be actively utilized. The article does a great job of showcasing how understanding and controlling friction is actually key to a whole host of applications,from designing efficient braking systems to creating effective robotic grippers.
It's easy to get caught up in minimizing friction to improve efficiency in things like engines and gearboxes, but there's so much more to it. Think about how something like climbing rope would be useless without the friction generated between the rope and a belay device. Or even simpler, how we wouldn't be able to walk without the friction between our shoes and the ground.anyone else have examples of situations where a deep understanding of friction, its control and manipulation, has led to an ingenious design solution? I'm especially interested in hearing about examples from the maker community and their projects. What seemingly simple projects required a really in-depth consideration of friction to succeed?
