Simple machines

I was really having trouble thinking of a good response to this prompt, but then I remembered something I learnt when I studied history. I couldn't remember the details, so I googled, and then I went out to the workshop.

There are, apparently, six "classical simple machines" (I only remembered five).

Archimedes named the first three. To save spamming you with too many pictures, I have joined them together.
I give you the lever, the screw and the pulley:

Later Greek philosophers defined another two: the wedge and the windlass. The windlass is a bit difficult to make out, because it has the cables and fishing nets wrapped around it.

And finally, during the Renaissance, scientists added the sixth: the inclined plane. It's a bit blurred, because it was dark and I didn't want to use a flash, so the exposure was long and the guy was moving.


What a great response! I'd never heard of these, so now I've learned something.

ETA: Just wanted to clarify that I'd heard of them individually but not as a 6-machine collective, or even as machines.

Thank you.

*g* No worries; I would not have assumed that you didn't recognise a chisel.
That's an awesome and very educational response to the prompt!
Thank you. It is reassuring to me to know that some small parts of my education stuck in my brain.
How fascinating - I didn't know this bit of history so I have learnt something new today.
Thank you. And thank you for the prompt - it was interesting collecting the pictures.
That was a very interesting read, and nicely accompanied by your pics.
Thank you. I'm glad you found it interesting.
Oh, this is a great response!
Thank you.
