Update: The Faming of the Screw
In the past month or so, this image has gotten popular. It first appeared in an entry where I discussed
the disadvantages of using a screw as a form of locomotion, as part of a series on why the lever is the best choice of simple
machines for organisms to use for movement. I quickly sketched this image in Illustrator to show the basic principle of how
a screw works.
As of this writing, if you go to Google Image Search
and look up "Simple
Machine: Screw" or some variation thereof, this image is the first one to come up. I suppose that it's becoming known
to physics students or teachers, as the page that carries it accounts for the majority of hits to PaaT.
If you've come to this site to find this image, you're welcome to make use of it for any non-commercial purpose. All I ask
is that you drop me a line at
email@example.com and let me know what you plan to use it for.
