Point masses 
and 
are placed at the opposite ends of a rigid rod of length 
and negligible mass. The rod is to be set rotating about an axis perpendicular to it. The position of point 
on this rod through which the axis should pass, so that the work required to rotate the rod minimum angular velocity 
is minimum, is given by
