Question

A rotating space station is said to create "artificial gravity"-a loosely-defined term used for an acceleration that would be crudely similar to gravity. The outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. If the space station is 190 m in diameter, what angular velocity would produce an "artificial gravity" of 9.80 m/s^2 at the rim? rpm

Explanation / Answer

Space station diameter = 190 m

r = 190/2 = 90 m

w=sqrt (g/r) = sqrt(9.8/90)= 0.33 rad/s
