Hydrodynamic Journal Bearings
The problem is that bearings (i.e. all journal bearings excluding tilting pad bearings) support a vertically downward load or force with a displacement that is not directly downward but at some angle with rotation from bottom dead center. This is illustrated in Figure 1 for a high speed, lightly loaded unstable journal bearing.
