In the design of a space station to operate outside the earth’s gravitational field, it is desired to give the structure a rotational speed N which will simulate the effect of the earth’s gravity for members of the crew. If the centers of the crew’s quarters are to be located 12 m from the axis of rotation, calculate the necessary rotational speed N of the space station in revolutions per minute.
