Axis of Rotation
a. Relative Centrifugal Field (RCF) is the ratio of the centrifugal acceleration at a specified radius and speed (rw
gravity (g) according to the following formula: RCF = r/g — where r is the radius in millimeters,  is the angular velocity in radians per
second (2  RPM /60), and g is the standard acceleration of gravity (9807 mm/s
