How Does Rotation in a Spinning Space Station Affect Astronauts?

Click For Summary
SUMMARY

The discussion focuses on the effects of rotation in a spinning space station, specifically a design resembling a large wheel with a diameter of 94 meters. To simulate Earth's gravity, astronauts at the rim must achieve an acceleration of 9.8 m/s². The key equations involved include centripetal acceleration (Ac = v²/r), tangential velocity (v = 2πr/t), and the relationship between linear velocity and angular velocity (v = rω). Participants also explore the perspectives of both an observer outside the station and an astronaut inside, highlighting the sensation of artificial gravity due to centrifugal force.

PREREQUISITES
  • Understanding of centripetal acceleration and its formula (Ac = v²/r)
  • Familiarity with angular velocity and its relationship to linear velocity (v = rω)
  • Basic knowledge of gravitational acceleration (9.8 m/s²)
  • Ability to apply mathematical equations to physical scenarios
NEXT STEPS
  • Calculate the required period of rotation for a space station with a 94m diameter to simulate Earth's gravity
  • Research the effects of centrifugal force on human physiology in microgravity environments
  • Explore advanced concepts in rotational dynamics and their applications in space engineering
  • Investigate existing designs of rotating space habitats and their operational principles
USEFUL FOR

Aerospace engineers, physics students, and anyone interested in the design and functionality of space habitats and the effects of artificial gravity on human health.

Homework Statement


One design for orbitting space stations has a structure that is very much like a large wheel. The astronauts live near the rim, where the spinning of the wheel provides an acceleration that mimics the effects of gravity.
a) If the station has a diameter of 94m, what period of rotation would be required for the astronauts at the rim to experience an acceleration similar to the acceleration of gravity on earth?
b) Imagine that you are sitting motionless in a spacecraft outside the space station. You are watching the space station spin. Explain the effects on the astronauts who are spinning in the space station from your frame of reference.
c) Imagine that you are now an astronaut on the space station. Explain the effects on your body from this frame of reference.

Homework Equations


Ac= v2/r
v= 2pir/t
Fc=mv2/r
Gravity on Earth = 9.8 m/s2

The Attempt at a Solution


a) Yet again my textbook and module booklet give me absolutely no help towards this problem. I know I need to find the revolutions per second or how long it takes for a revolution to occur. I don't know how to get this number though. The only way I can think of is guess and check...lol Please help!
b) I'm guessing they want something along the lines of the person outside is seeing the astronaauts maintain a velocity as they rotate around the space station. However, they give a very large answer box, and I'm not sure how I should expand on this idea...
c) I'm guessing the person is not feeling much of a difference in the space station as they would on earth, as the rotation is keeping artificial gravity. The person has a centrifugal force pinning him down to the side.

Hi ahrog! :smile:

(have an omega: ω :wink:)

You have all the equations there …

just use v = rω.
