[Request] How long would a straight item (for example a metal beam) have to be before one would notice the curvature of the Earth under it?

Some assumptions:
Both the Earth and the beam are made of hard materials that do not give under weight (i.e., we replace the ground under the item with a hard material).
The ground under is equidistant from the center of the center of the earth. There are no mountains or hills. The ground is what we would call "flat."
The beam is placed along the equator, at sea level.
Noticing the curve of the Earth implies that a human would be able to detect a gap between the beam and the surface of the earth.
