Solution: Looks to me like the problem lies in the units again. m 2 . lol. I understand your confusion (heck im confused too), but lets see how i can explain this. Anyone care to expand on this? Enter your email below to unlock your verified solution to: Rotating Space Stations. Because in my textbook they say the period is a "radian measure" but what do they mean by that? The major requirement for an astronaut to experience artificial gravity is that he is in contact with the rotating floor of the spaceship. Rotating Space Stations.? (b) If the space station is a waiting area for travelers going to Mars, it might be desirable to simulate the acceleration due to gravity on the Martian surface (3.70 m/s2). Sn or Sib. One problem for humans living in outer space is that they are apparently weightless. For a better experience, please enable JavaScript in your browser before proceeding. so i can't use that equation then? (a) If the diameter of the space ohh...that would change my answer. in my physics book it says it's the radius...sorry if i sound stupid...they just didn't teach this to us, so i'm having difficulty understanding. ), gravity, classical mechanics, Frame of reference question: Car traveling at the equator, Seeking a simple logical argument to an interesting statement (spring-mass motion), Determining the starting position when dealing with an inclined launch. P8.72). The attempt at a solution I assumed that to do this problem, Fcp had to equal the force of gravity. However, it is actually in radians per second (2pi radians being 1 revolution). An unit circle has a radius 1 so therefore it has a 2pi circunference, you measure around this circle a distance x. Radian is the distance in a unit circle. No matter how tightly the li... 20Q: Children are told to avoid standing too close to a rapidly moving t... 62E: Choose the larger atom from each pair.a. i can't seem to figure that one out...you have meters on the top and m/s on the bottom...so wouldn't the answer be in seconds? For a better experience, please enable JavaScript in your browser before proceeding. it seems that if i divided my answer by the angular speed i could get the answer in seconds...but there aren't any angles involved in this problem...that's a few chapters ahead of where we are. Genomic data 'catches corals in the act' of speciation and adaptation, Bats can predict the future, researchers discover, Neanderthal children grew and were weaned similarly to modern humans, Rotational Intertia of a rotating Space Station, Artificial Gravity and a Rotating Space Station, Space station(non rotating! One problem for humans living in. It all comes from the rotational motion formula s = r*theta - which is a radian measure. One way around this problem is to design a space station that spins about its center at a constant rate. A rotating circular space station can create artificial gravity for its passengers. Is there anyone that can clarify? [14] Another problem (oy! there must be something simpler....but what... v= sqrt rg....sqrt (510m x 9.8 m/s^2) = 70.69 m/s, Genomic data 'catches corals in the act' of speciation and adaptation, Bats can predict the future, researchers discover, Neanderthal children grew and were weaned similarly to modern humans, Rotational Intertia of a rotating Space Station, Artificial Gravity and a Rotating Space Station, Space station(non rotating! The circle formed by the tube has a diameter of about D = 1.02km. In the film 2001: A Space Odyssey, a wheel like space station achieves artificial gravity by spinning around its axis. But angular velocity is defined by the relation, = 2/T --------------------(2) Where T is the time period of revolution. Yes, the period would be measured in seconds. What value of g did you use? I don't see anything wrong with your physics. Physics problems: dynamics ; Problem 5. Using g = 9.81 N/kg, I get v = 24.66 m/s (to two decimal places). When 100 people move to the center of the station for a union meeting, the angular speed changes. Solution 49E The diameter of the space station is 800 m. So, the radius will be 800/2 = 400 m. As it is rotating about it’s centre, the centripetal acceleration felt by a person sitting at the circumference will be, a = v / r---------------------(1) The radius we already know, so let’s put the value in equation (1) to get the angular velocity.
