Smoke and Mirrors: Ultra-Rapid-Scan FT-IR Spectrometry

The bending moments generated by a centrifugal field can be readily visualized. For the case of the tilted disk, the forces tend to bend the disk back to flatness. There is also a thinning of the center of the disk which couldn’t be seen in the deformation slide because it was obscured by bending. The moment of the flat tilted disk also produces undesirable bearing loads. If the back surface of the disk is tilted out by an amount equal to the front, the bending moments will cancel, and in the next slide the thinning effect will be visible.
