Pulleys Memes

The eternal quest to find real-world examples of those perfectly frictionless pulleys from physics textbooks has finally ended! Every physics student has solved countless problems with ideal pulleys that have zero friction, zero mass, and inextensible strings—objects that supposedly don't exist in nature. Yet here they are, hanging on power lines like mythical creatures spotted in the wild! Next thing you know, someone will find a cow that's actually a perfect sphere...

Every physics student has that moment of recognition when textbook diagrams suddenly manifest in real life! Those pulleys and tension systems that seemed like abstract torture devices in homework problems are actually EVERYWHERE once you start looking. The electrical line system is basically a living physics problem – complete with multiple pulleys, tension forces, and enough variables to make your TI-84 calculator cry. Next time your professor asks "when will you use this in real life?" just point at the nearest power line and say "it's been haunting me since chapter 3!"
