Chapter 6, Problem 10CQ
It’s been proposed that future space stations create “artificial gravity” by rotating around an axis. (The space station would have to be much larger than the present space station for this to be feasible.)
a. How would this work? Explain.
b. Would the artificial gravity be equally effective throughout the space station? If not, where in the space station would the residents want to live and work?

Engineers and science fiction writers have proposed designing space stations in the shape of a rotating wheel or ring, which would allow astronauts to experience a sort of artificial gravity when walking along the inner wall of the station's outer rim.
(a)
Imagine one such station with a diameter of 129 m, where the apparent gravity is 4.00 m/s2 at the outer rim. How fast is the station rotating in revolutions per minute?
(b)
What If? How fast would the space station have to rotate, in revolutions per minute, for the artificial gravity that is produced to equal that at the surface of the Earth, 9.80 m/s2?

Enter an expression for the gravitational constant, in terms of the distance between Earth and the moon, RME, Earth’s mass,ME, and the moon’s period of rotation around Earth, T. b)Using the expression you entered in part (b) and taking the rotational period of the moon to be T = 27.1 days, what value would Newton have calculated for the gravitation constant, in units of N⋅m2/kg2?

WHAT IS ITS RADIAL ACCELERATION?arrow_forwardIn a science fiction movie, a spacecraft has a rotating section to provide artificial gravity for the long voyage. A physicist watches a scene filmed from the interior of the spacecraft and notices that the diameter of the rotating section of the craft is about five times the height of an astronaut walking in that section (or about 10 m). Later, in a scene showing the spacecraft from the exterior, she notices that the living quarters of the ship rotate with a period of about 30 s. Did the movie get the physics right? Compare the centripetal acceleration of a 1.7 m–tall astronaut at his feet to that at his head. Compare these accelerations to g.

The rim revolves around the center of the space station at a speed of 300 (m/s). If the radius of the station is 3,000 (m). 1.) Draw and label a diagram for this case. 2.) What is the rotational speed of the space station? 3.) From the equation a = V^2/r (a = simulated gravity/acceleration), calculate the acceleration (a) at the rim. 4.)

Without artificial gravity, human growth is stunted and biological functions break down. An effective way to create artificial gravity is through the use of a rotating enclosed cylinder, as shown in the figure. Humans walk on the inside of the outer edge of the cylinder, which has a diameter of ?=2635 m that is large enough such that its curvature is not readily noticeable to the inhabitants. (The space station in the figure is not drawn to scale.) Once the space station is rotating at the necessary angular speed ?ω to create an artificial gravity of 1 ?, how many minutes would it take the space station to make one revolution?arrow_forwardNASA is expected to send a 2600-kg satellite 450 km above the earth's surface.
