#### BASIC DESIGN SELECTION TABLES

The unsupported length is the dominate factor, because the critical speed is inversely proportional to the square of the unsupported length Using a fixed unsupported screw length, the critical speed can be varied by the selection of the screw diameter, lead and end bearing supports Critical Speed Formula.
