ELI5: Why do we hit things when they don't work?
gpt
In a lot of older equipment frayed wiring and jammed components actually can be "fixed" by banging the frame hard enough.

It doesn't fix the main cause of the problem, but it's often enough to get stuck gears and corroded contacts working again for a while.

It's less useful for modern electronics, but we still do it out of habit.
