on the calculated values of hi, we calculate the SIased
dimensionless radial F and tangential t components of the force
acting on the rotor pivot in ia hydrostatic bearing. The.radial
force is directed along the line of!the pivot and bearing centers,

the Itangential force is~perpendicular to the line of the centers.

the relative eccentricity e,
the relative rotational velocity of the
