Why is it that when you pull out a cheap plastic drawer, there is sometimes a squeak that makes your ears bleed? (exaggerated.)
I know it has to do with friction but why does it squeak? Or rather, what causes the squeak?
If I run my finger down a surface, there is no squeak. Even if there is it's not nearly as high-pitched...
What's the difference between the two situations?
