Atheoretical model has been developed for a synchronous thermal instability that is caused by differential viscous shearing in bearings of overhung rotors. This model employs an unbalance threshold criterion for instability instead of utilizing a tra

In Part I, a theoretical model was developed for a synchronous thermal instability that is caused by differential viscous shearing in bearings of overhung rotors. This second part used computer programs, which were based on the theoretical model, to

Religion played a prominent role in the 2020 presidential campaign. Donald Trump overtly courted white evangelical Protestants and Catholics, while Joe Biden emphasized his Catholicism far more than any Catholic candidate in American history. Did rel

Labyrinth seals in various kinds of rotating machinery often generate driving force components that may increase the unstable vibration of the rotor. The evaluation of labyrinth seal forces has been documented by CFD analysis but the leak path geomet

This paper will discuss the unexpected high vibration seen on both the drive end and the driven end of a high-speed disc pack design coupling, in addition to the documented vibration at the coupling spacer mid-span location. The coupling was being us
