Asked by Rachel

Suppose a cylindrical habitat in space 7.70 km in diameter and 25.0 km long has been proposed. Such a habitat would have cities, land, and lakes on the inside surface and air and clouds in the center. They would all be held in place by rotation of the cylinder about its long axis. How fast would the cylinder have to rotate to imitate the Earth's gravitational field at the walls of the cylinder?

R w^2 = g = 9.8 m/s^2

R = 3850 m
The length of the cylinder does not matter.

Solve for the angular (spin) velocity w in radians per second.

This assumes it is spinning about the axis of the cylinder.
