It is a piece of equipment that puts objects into rotation

The use of large centrifuges to simulate a feeling of gravity has been proposed for future long-duration space missions.

Exposure to this simulated gravity would prevent or reduce the bone deterioration and 

muscle atrophy that affect individuals exposed to long periods of freefall. [

Just like the gravitron…a rotating object will be pressed to the outer wall, inertia simulates (feels like) gravity

The speed of the rotation controls the amount of “artificial gravity”

Small structures would have to rotate very fast to create 1 g

Most people can’t tolerate fast rotations…3 rpm (max)

Sooo…to get 1 g at 1 rpm would need a very large structure ..2 km in diameter

What is a piece of equipment that puts objects into rotation?

What is the purpose of a human centrifuge?

How is gravity simulated?

Centrifuge

To simulate (make it feel like) gravity

Revolve a spaceship

Would a space station need to be a certain size?

Why is such a large structure needed for a space station?

Is there a place on the space station where you would experience 0.5g?

Yes, it will have to be at least 2 km across

To decrease the # rpm

½ way to the center
