If I can add a bit to the simple machine discussion. While the person who commented pointed out that a simple machine (like the incline plain) doesn’t have moving parts, the machine itself doesn’t have move, it has to cause motion to be a machine. Thats where the “applying a force to do work on a load” part of the definition comes in. You must cause motion to do work. If you try to lift something and it doesn’t move, you applied forced but did no work. So while the incline plain doesn’t move, it reduces the force required to “lift” an object, so if your slide or roll something up the incline plain it is allowing you to do work, and making that work easier makes it a machine.

I would also contend that a screw is just a more complex version of an incline plain, since it is essentially just an incline plain wrapped around an axis. Are you aware I was a math and science guy on school? 😁

I hope I got this all correct, despite my education, I basically got hit in the head for a living much of my adult life. 🤷‍♂️

I kept all of my vinyl from the 70s and 80s (or my parents did - and yes, I should get the rest of them since I'm 58). But there's a new little record store near my house now and it is quite fun to browse!
