Three major types are radial or journal thrust and guide bearings. blower A fan that operates where the resistance to gas flow is predominantly downstream of the fan. boundary condition Any condition that marks or describes a limit or a bound. brake horsepower The horsepower developed by an engine as measured by the force applied to a friction brake or by an absorption dynamometer applied to the shaft or flywheel. catastrophic failure A sudden failure without warning as opposed to degradation failure that generally prevents the satisfactory performance of an entire assembly or system. cavitation Formation of gas- or vapor-filled cavities within liquids. centrifugal force An outward pseudo-force in a reference frame that is rotating with respect to an inertial reference frame. The pseudo-force is equal and opposite to the centripetal force that acts on a particle stationary in the rotating frame. Glossary 293 centripetal force The radial force required to keep a particle or object moving in a circular path which can be shown to be directed toward the center of the circle. chronic- Of continued duration. chronology The arrangement of data in order of .
