I have never worked with those units before.

What is viscosity measured in? http://www.hydramotion.com/pdf/Website_Viscosity_Units_V2.pdf

I'm not saying the reasons are wrong in themselves for they are not but the reason you get this lowered gravity at the equator, instead of what should happen. Could this be due to the lower density material that is separating you from the main source of the Earth's gravity? That is what I'm thinking at least, but I haven't worked it out as yet.

What I was suggesting is that if the Earth was even density the equatorial regions would have the higher gravity. The Equatorial Regions are like the edge of the disc described by Janus. Those graphs would be different if the disc had a varying radial density as does the Earth.

The Earth flexes under the influence of the tidal forces of the Sun and the Moon. If it does this twice a day and don't see why the oblateness should be much of a problem to get rid of. As the Earth's slows its rotation the oblateness would disappear.

That was the point I was trying to lead to. If in your situation the center is where the gravity is the least, why is it currently stronger at the Poles? At what degree of oblateness would the effect be zero again? Logically there is no place or shape that will achieve this. So why the difference between extreme oblateness and mild oblateness? IMO it is because the core of the Earth is so much more dense it contributes to a greater proportion of the gravity. When we think of a flattened Earth we have also evened out the density of the material as well.

I was attempting to show why I think you are both wrong but the idea got split off from the thread. I am tempted to think if the Earth is an oblate spheroid you would be wise to consider where and what the additional dimension is composed of.

It was so potent I found you didn't need to drink it, I'd just breath the fumes when it was in my mouth. It definitely wasn't pleasant but it was loaded with something. I had a hangover for the whole of the following week. PS He might have added heaps of sugar to sweeten the gooseberries!

That guy had the weirdest sense of humour ever. Here's a bender :

The words rotational deformation and vodka reminded me of the worst inebriation I inflicted on myself. That day the Earth started rotating upwards and I found it impossible to stand for I could no long tell which way was up. This was on gooseberry wine my father had brewed.

There doesn't seem to be an easy answer to this problem for any search for the answer seems to be directed to a Flat Earther situation. One thing I did learn is that if the sheet was wide enough there would be no drop off the gravitational strength with height. But I wasn't intending it to be an infinite sheet Earth either but just on that got more and more oblate? There was one YT which covered the topic in a humorous way. Is Earth Actually Flat? For a sphere we'd say at the poles but on a disced shaped Earth we might just say center as in center of the circular disc. Not the Earth's center.

Do you think that can be taken to the limit with the whole Earth as a spread out circular sheet will the gravity always be stronger at the center?

I'll try that next time.

We must be talking relative motion here. Of course the L3 stays in the same alignment as ever but the unstable planet there moves off with some speed. What speed did Janus give it?

The line we'd take as we slid off the merry go round is not a straight line but a curved line across the surface of the spinning disc. It is a line described by the Coriolis Effect.

That works too but usually I get the problem when I'm the center of attention and I need the word straight away. It can be really embarrassing.

My first question to Janus (regarding this) used the L3 point as my reference point "Janus - in your simulation did you start Theia off at the L3 point from stationary?" http://www.scienceforums.net/topic/88515-how-to-calculate-the-force-of-gravitational-attraction-in-co-orbiting-planets/page-2#entry862799 The speed through or away/toward the L3 would make a big difference to the simulation. How did Janus assign an initial value to that?

Good answer, but not that much different as the L3 point is on the same line anyway.

Deja vu?

I think it was meant to be brutish not British!

If you don't like centrifugal force you could always say it has "more inertia" at the equator therefore weighs less. If inertial mass equals the inertial mass can I rightly say something has "more inertia"? More momentum or even more angular momentum (wrt the center of the Earth) rather than more inertia might be more correct scientifically.

First thing to learn is to spell enzymology and also difference and abbreviation. I'll let you get away with iam and plz. http://en.wikiversity.org/wiki/Enzymology Enzymology is the study of enzymes, their kinetics, structure, and function, as well as their relation to each other. Is that the Km you were looking for.

I'd like you to tell me what it should be called then.

Interesting and that lead to the link on presque vu or TOT. "http://en.wikipedia.org/wiki/Tip_of_the_tongue I get a often especially when I'm anxious. That is worse than jamais vu, I'd say.
