Hey LJ’s,

I found these pictures of a project I made last semester for my Astronomy class. I chose to make a model that would demonstrate a concept we learned in the class, I selected Centrifugal Force.

This model demonstrated the tendency of rotating mass to push outward perpendicular to the axis of rotation. Demonstrated by the arms that lift up and the little wooden weights that move to the end of the arm.

Anyways, it worked!

Its made from various plywood, some mahogany, some unknown hardwood dowels, and an ordinary fan belt.

It was fun to make and a neat little toy to take up space, but I wanna mess around and make some more simple machines from wood, any ideas?

Looks like a fun little project. Being a physicist, the title caught my interest and I smiled, but that is just because it brings back some memories from college.

Oh, there’s a word “centrifugal”.

There’s just no such FORCE. ;-)

My suggestion would be to build a “Perpetual Motion” machine. Lots of money to be made there! Lol.

If you have a lathe, you can always illustrate a black hole by an eliptical cone that swallows up small balls spun around the lip.
