I read about an equation; E = mc^2 and concluded that m=\frac{E}{c^2}. Therefore, I assume that one can create Earth gravity by emitting energy equivalent to mass of earth. I also read that, simply put, that a stars gravity can be amplified when it's core collapses, or compresses creating...

This is not actually homework, I'm just trying to calculate the speeds/forces needed to create 9,81 m/s2 artificial gravity (outward) within a rotating barrel in space. Homework Statement I read on the internet that a space station would require a diameter of 224m and an angular speed of 2...

A rotating spacecraft uses centripetal force to produce artificial gravity. If i know the radius of the space station and how fast it spins at, what is the apparent value of g on the surface of the station? I know how to calculate the centripetal acceleration: a=v^2/r But I was thinking...

E=mc2 says that mass and energy are interchangeable. to make interstellar space flight possible artificial gravity must be generated. assuming that energy generation is not a factor, according to the equation given sufficient energy a gravity field could be generated. most everything that...

Every spaceship in sci-fiction movie I watch has some kind of artifical gravity. But is that possible? Are there any theories on how can be some kind of artificial gravity created without having a planet/black hole stucked at the bottom of your spaceship or everything magnetised? So far I only...

In discussions, and novels, about deep space missions, we frequently read of the plan to spin the spaceship to produce artificial gravity. This intuitively makes good sense. But would it work in a ship that is very, very, very far away from any stars or other matter? That is, if the ship is...

Homework Statement If a washing machine's drum has a radius of 27 cm and spins at 4.1 rev/s, what is the strength of the artificial gravity to which the clothes are subjected? Express your answer as a multiple of g. Homework Equations Ar= v2/r The Attempt at a Solution I tried...

Homework Statement A space station, in the form of a wheel 135 m in diameter, rotates to provide an "artificial gravity" of 3.80 m/s^{2} for persons who walk around on the inner wall of the outer rim. Find the rate of rotation of the wheel (in revolutions per minute) that will produce this...

To create artificial gravity, the space station shown in the drawing is rotating at a rate of 0.85 rpm. The radii of the cylindrically shaped chambers have the ratio rA/rB = 3.80. Each chamber A simulates an acceleration due to gravity of 10.0 m/s2. Find values for the following. (a) rA...

"Artificial Gravity" Homework Statement A space station in the form of a large wheel, 333m in diameter, rotates to provide an "artificial gravity" of 9m/s^2 for people located on the outer rim. Find the rotational frequency of the wheel that will produce this effect. Answer in units of rpm...

I've heard some great stuff about artificial gravity. The different ways it could be achieved. So far, I've heard that it can be done by rotation (reaching momentum), magnatism, keep accelerating something like a spacecraft so that people inside it sticks to the back side of the craft...

a space station is composed of 2 concentric circles. the inner circe has diameter 5km(r=2.5 km) and the outer has a diameter 10 km (r=5km). g= 1.64 m/s^2 for the outer circle and i need g for the inner circle i know g = G *M/r^2 so perhaps i can calculate M? 1.64 = 6.67E-11 * M/5000^2 so M=...

I've been staring at this problem for quite a while now, and I don't really know how to approach it. Any guidance would be greatly appreciated. What we have is a rotating cylinder to create artificial gravity (equivalent gravitation acceleration of ag where a is a constant). We are asked to...

Hi, Question about fictitious force, The set-up is a torus rotating in space of radius r. First part involves working out the speed of rotation v, for which an artificial gravity of 1g will be created in the torus. Which is just the centripetal acceleration (centrifugal force?) For r =...

Lets say you're on a spaceship, and the floor of the ship is pulling you and the other objects in your ship toward it. (it might be easier to think of this in terms of a computer simulation) If you go beneath the floor of your ship, you are not affected by it's artificial gravity. Now...

I was wondering what sort of advances it would take for making artificial gravity seem within reach for ships (not based on spin). I was thinking something along the lines of maybe using extremely pressureized gas. I realize the contribution from pessure is generally small compared to...

I'm a Junior, and I am participating in a competition. A team I am on annually joins in the ISSD competition, or International Space Settlement Design competition, which is sponsored by NASA engineers. Having participated since my Freshman year, I am currently working on the structural...
