What if there was a pole, whose length was the circumference of the Earth?

Click For Summary
The discussion revolves around the hypothetical scenario of placing a pole, equal to the Earth's circumference, vertically on flat land. Participants explore three main outcomes: the pole wrapping around the Earth, jutting out into space, or snapping due to material limitations. The consensus leans towards the pole wrapping around the Earth, as the curvature of the Earth is shallow relative to the pole's length. Concerns about material properties highlight that no known material could maintain such rigidity without bending or breaking. Ultimately, the conversation emphasizes the complexities of physics and material science in addressing this imaginative scenario.

F = ma, I say - a slight touch (F) would produce a slight acceleration (a). So it would do something, even if the motion would be so small you couldn't measure it.
Well OK. I guess the same thing could be said about the Queen Mary. A slight touch sets it moving imperceptibly?

An other way I thought about looking at this thought experiment is if the pole was infinitely long. Would the pole keep on warping around the Earth? Or will it warp until ends meet (well sorta) and the equal force from each side would cancel any other warping and the rest of the extent will keep on jutting out into space?

Just something I thought would be interesting to add to this already interesting thought experiment.

Edit: Assume that the infinite pole is behaves the same way as the already finite pole.

Uh, you lost me. An infinitely-long pole would form a helix of infinite width. I don't see where you're going with this.

Well I sort of worded it wrong, I meant a helix when I suggested my first option I just didn't word it properly. Sorry about that.
