Notes
1. In my notes for the rotating space station, I0 = initial moment of inertia; Mc0 = initial # of
crew members on outer rim; Mcx = final # of crew members on outer rim; a0 = initial
apparent gravity on outer rim; mc = mass of an average crew member; ax = final apparent
gravity (after 100 crew members move to the center). Since everyone has the seventh edition
of Serway, here is the problem from the fourth edition written out for you:
“A wheel-shaped space station has a radius of 100 m and a moment of inertia of 5.00x10^8
kg*m^2. A crew of 150 live on the rim, and the station is rotated so that they experience an
apparent gravity of g [See Fig P11.27 in Seventh Edition]. If 100 people move to the center,
the angular rotation speed changes. What apparent gravity is experienced by those remaining
at the rim? Assume an average mass of 65.0 kg per crew member.” (Serway, Physics for
Scientists and Engineers with Modern Physics, Fourth Ed, page 330, problem 11.34).
2. In my notation above, Ex = Example and Prob = Problem.
