How Good Is Your Geographic? [5]

[Tazio]

Here is an easy one:



This equation is a mathematical expression of what geographical characteristic?

[gadjo_dilo]

It's easy for those who speak old chinese.......

not chinese... I see angular velocities, orbital periods, densities, gravitational constants, massive masses, ... the music of the spheres

[schmenke]

Sounds like donkey is on the right track.
Looks to be a measure of force, based on variances of accelerations. So, I'll guess it's the measure of gravitational pull between planets?

[Tazio]

You guys are on the right track, but it has to do specifically with the mass of the earth!!

[donKey jote]

I see an e for equator, a p for pole, a w for rotation, an M for massive mass of the Earth... the faster you spin the thicker you get

[schmenke]

A measure of the centrifugal force caused by the earth's rotation?

[donKey jote]

those aren't a for acceleration, think r for radius... a measure of Billy's missus' bulge around the belly when she spins ?

That's it, an equation for equatorial bulge!
Although I think schemke got it first!!

[donKey jote]

it's actually an approximation for the flattening factor due to self gravity of a rotating fluid spheroid of constant density...
the faster you spin the thicker you get... over to schmonkey
