Does the rotation of Earth affect gravity?

While the spinning of the Earth doesn’t directly affect gravity, it does off-set it a little. At the north and south poles objects weigh exactly what they should, and at the equator things weigh slightly less.

How Does height affect gravity?

gravity increases with height. gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up) gravity is caused by the Earth spinning. gravity affects things while they are falling but stops when they reach the ground.

Could a space elevator reach up to Earth’s orbit?

Proposals are now circulating for a free-standing tower or “space elevator” that could reach up into the geosynchronous orbit around the earth. Such a tower would be an alternative to rocket-based transport, and drastically reduce the amount of energy it takes to get into space.

What is the height of geostationary orbit from the ground?

He considered a similar tower that reached all the way into space and was built from the ground up to the altitude of 35,786 kilometers, the height of geostationary orbit. He noted that the top of such a tower would be circling Earth as in a geostationary orbit.

What is the maximum tension on a space elevator cable?

Cable section. The greatest tension on a space elevator cable is at the point of geostationary orbit, 35,786 km (22,236 mi) above the Earth’s equator. This means that the cable material, combined with its design, must be strong enough to hold up its own weight from the surface up to 35,786 km (22,236 mi).

Are carbon nanotubes strong enough to build an Earth space elevator?

Available materials are not strong enough to make an Earth space elevator practical. Some sources have speculated that future advances in carbon nanotubes (CNTs) could lead to a practical design. Other sources have concluded that CNTs will never be strong enough.
