Programs: AXIS ROTATE, PRINCIPAL AXIS, and PRINCIPAL MOMENT
By: Ben Axelrod

    I made these programs to make dealing with second moments 
(moments of inertia) a lot easier.  Here is what they do…

Axis Rotate:  Finds new second moments for a rotated coordinate 
system.  Note, the angle of rotation is in degrees.  (AXISROT.83P)

Principal Axis:  Finds the angle to rotate axes that yields 
maximum and minimum values for the second moments.  (PRNAXIS.83P)

Principal Moment:  Finds the possible maximum and minimum values 
of the second moment.  (PMOMENT.83P)
