[QUOTE="kuruman, post: 6864026, member: 192687"] Which arrow represents the centripetal force that you say is perpendicular to the Earth's axis? It would help if you put some identifiers on your drawing like the angular velocity vector of the Earth. Also, why do you think it is necessary to invoke the oblateness of the Earth? Would the plumb bob at, say, a ##45^{\text{o}}## latitude point straight at the center of a perfectly spherical rotating Earth? [/QUOTE]
