BASIC NEWTONIAN PHYSICS: we have a center of gravity which is located ABOVE THE EQUATOR, given the fact that the northern hemisphere has more mass than the southern hemisphere. Then, the accepted law of universal gravitation tells us that the Earth should revolve facing the Sun with its North Pole.
According to this formula, the position of the centre of gravity varies according to the shape of the object.
"The area of land in the northern hemisphere of the earth is to the area of land in the southern hemisphere as three is to one.
The mean weight of the land is two and three-quarter times heavier than that of water; assuming the depth of the seas in both hemispheres to be equal, the northern hemisphere up to sea level is heavier than the southern hemisphere, if judged by sea and land distribution; the earth masses above sea level are additional heavy loads - we include here all the mountains/hills.
But this unequal distribution of masses does not affect the position of the earth, as it does not place the northern hemisphere with its face to the sun. A “dead force” like gravitation could not keep the unequally loaded earth in equilibrium. Also, the seasonal distribution of ice and snow, shifting in a distillation process from one hemisphere to the other, should interfere with the equilibrium of the earth, but fails to do so."
The northern hemisphere has a greater mass than its southern counterpart.
The unequally loaded perfect oblate spheroid (first four layers) DEFIES the law of attractive gravity.
Remember, if you want torque calculations, you must explain the seismic waves anomalies. If you cannot explain the seismic wave anomalies, that means that there is no molten outer core.
Very simple: the northern hemisphere is heavier than the southern hemisphere. Thus, according to the formula put forth by Newton, the force of gravity should place the North Pole facing the Sun.
Here are more gravitational anomalies which defy your request for torque calculations as well as Newton's supposed law of universal gravitation.
Mountainous masses do not exert the gravitational pull expected by the theory of gravitation. The influence of the largest mass on the earth, the Himalaya, was carefully investigated with plumb line on the Indian side. The plumb line is not deflected as calculated in advance. The attraction of the mountain-ground thus computed on the theory of gravitation, is considerably greater than is necessary to explain the anomalies observed. This singular conclusion, I confess, at first surprised me very much. (G. B. Airy.) Out of this embarrassment grew the idea of isostasy. This hypothesis explains the lack of gravitational pull by the mountains in the following way. The interior of the globe is supposed to be fluid, and the crust is supposed to float on it. The inner fluid or magma is heavier or denser, the crust is lighter. Where there is a mountainous elevation, there must also be a protuberance beneath the mountains, this immersed protuberance being of lesser mass than the magma of equal volume. The way seismic waves travel, and computations of the elasticity of the interior of the earth, force the conclusion that the earth must be as rigid as steel; but if the earth is solid for only 2000 miles from the surface, the crust must be more rigid than steel. These conclusions are not reconcilable with the principle of isostasy, which presupposes a fluid magma less than 60 miles below the surface of the earth. There remains a contradiction between isostasy and geophysical data.
Over the oceans, the gravitational pull is greater than over the continents, though according to the theory of gravitation the reverse should be true; the hypothesis of isostasy also is unable to explain this phenomenon. The gravitational pull drops at the coast line of the continents. Furthermore, the distribution of gravitation in the sea often has the peculiarity of being stronger where the water is deeper. In the whole Gulf and Caribbean region the generalization seems to hold that the deeper the water, the more strongly positive the anomalies.
As far as observations could establish, the sea tides do not influence the plumb line, which is contrary to what is expected. Observations on reservoirs of water, where the mass of water could be increased and decreased, gave none of the results anticipated on the basis of the theory of gravitation.
In 1981 a paper was published showing that measurements of G in deep mines, boreholes, and under the sea gave values about 1% higher than that currently accepted. Furthermore, the deeper the experiment, the greater the discrepancy. However, no one took much notice of these results until 1986, when E. Fischbach and his colleagues reanalyzed the data from a series of experiments by Eotvos in the 1920s, which were supposed to have shown that gravitational acceleration is independent of the mass or composition of the attracted body. Fischbach et al. found that there was a consistent anomaly hidden in the data that had been dismissed as random error. On the basis of these laboratory results and the observations from mines, they announced that they had found evidence of a short-range, composition-dependent fifth force. Their paper caused a great deal of controversy and generated a flurry of experimental activity in physics laboratories around the world.
The majority of the experiments failed to find any evidence of a composition-dependent force; one or two did, but this is generally attributed to experimental error. Several earlier experimenters have detected anomalies incompatible with newtonian theory, but the results have long since been forgotten. For instance, Charles Brush performed very precise experiments showing that metals of very high atomic weight and density tend to fall very slightly faster than elements of lower atomic weight and density, even though the same mass of each metal is used. He also reported that a constant mass or quantity of certain metals may be appreciably changed in weight by changing its physical condition. His work was not taken seriously by the scientific community, and the very precise spark photography technique he used in his free-fall experiments has never been used by other investigators. Experiments by Victor Cremieu showed that gravitation measured in water at the earth?s surface appears to be one tenth greater than that computed by newtonian theory.
On the basis of newtonian gravity, it might be expected that gravitational attraction over continents, and especially mountains, would be higher than over oceans. In reality, the gravity on top of large mountains is less than expected on the basis of their visible mass while over ocean surfaces it is unexpectedly high. To explain this, the concept of isostasy was developed: it was postulated that low-density rock exists 30 to 100 km beneath mountains, which buoys them up, while denser rock exists 30 to 100 km beneath the ocean bottom. However, this hypothesis is far from proven. Physicist Maurice Allais commented: There is an excess of gravity over the ocean and a deficiency above the continents. The theory of isostasis provided only a pseudoexplanation of this.
The standard, simplistic theory of isostasy is contradicted by the fact that in regions of tectonic activity vertical movements often intensify gravity anomalies rather than acting to restore isostatic equilibrium. For example, the Greater Caucasus shows a positive gravity anomaly (usually interpreted to mean it is overloaded with excess mass), yet it is rising rather than subsiding.
A superb study of the seminal paper published by Roland Eotvos on gravitational anomalies almost 100 years ago:
