An Overview of Bearing Vibration Analysis
load is two dimensional and contained in a radial plane whilst under misalignment it is three dimensional. The movement is also periodic with base frequency equal to the rate at which the rolling elements pass through the load zone. Frequency analysis of the movement yields the base frequency and a series of harmonics.

Chapter 9: Column Analysis and Design
• The load-carrying capacity of a column is affected by the end support conditions. - Restraining the ends of a column with a fixed support increases the load-carrying capacity of a column. - Allowing translation as well as rotation (i.e. free end) at one end of a column generally reduces its load-carrying capacity.
