Prob. 2.3-3. a wire is used to hang a lantern over a pool. neglect the weight of the wire, and assume that it is taut, but strain free, before the lantern is hung. when the lantern is hung, it causes a 50-mm sag

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
