Physics was a long time ago. Need the equation for the force in gees on a rotating object. As in say the classic wheel shaped space station.

This one is about as simple as it gets:

That was the very first mainframe program I wrote in '67.
Relative Centrifugal Force= 0.00001118*radius in cm*rpm^2
or
RCF=0.0000283972*radius in inches*rpm^2Free software for calculating bolt circles and similar: Click Here

OK. University Physics, Mechanics Heat and Sound by Sears and Zemansky. Chapter 6 , section 2 circular motion, and section 3, Centripetal force:
It boils down to the velocity around the circle is: v = 2 pi R / T
After a bunch of derivitives.
the radial acceleration is: a = v squared / R
Now everyone know force is mass time acceleration so :
The radial force is the mass times the "speed" of the object going around the circle squared divided by the radius of rotation.
The units of Force will be dependant on the units of mass and linear measure.
Mass in grams and dimensions in cm = force in dynes.
Remember that G's are not a unit of Force
How much deeper do you want to go?
...lew...
on edit I see it was a waste of time

Weird, I never would of guessed its exponential with speed. I would of thought it would be linear.Play Brutal Nature, Black Moons free to play highly realistic voxel sandbox game.

Yup

If you ever get stuck on a basic, or even notsobasic, concept in Physics go to the HyperPhysics website at Georgia State University. It has a very easy to navigate visual tree of concepts or you can just use the index. It even has built in calculators and graphers for most of the formulas.
Bookmark it.

That is one of the better ones that I use regularly. Another is Eric Weisstein's Wolfram Mathworld. If you need the formula for anything mathematical it is there.Free software for calculating bolt circles and similar: Click Here
