They are so perfect they reveal not only how the physical world works but how our minds work as well!

Isn't a screw just a modified inclined plane? I think I remember that from school.

If you're going to go that vein, out of
ARTelevision's list, there are only three machines. The
lever, the
inclined plane, and the
pulley.
The
wheel and axle is just a lever that rotates 360°.
The
screw is just an
inclined plane wraped around a cylinder.
The
wedge is just an mobile
inclined plane.
The three simple machines that I listed are, however, very different from each other. So much so, I believe, that the only thing they have in common is that they all trade
distance for
force to perform the same amount of
work (likely, the definition of a machine).
