298 Root Cause Failure Analysis

longitudinal Pertaining to the lengthwise dimension.
lubricity The ability of a material to lubricate.

machine train A series of machines containing both driver and
driven components.
mandrel A shaft inserted through a hole in a component
for support.
manifold Piping system that either gathers multiple-line
fluid inputs into a single intake chamber
(intake manifold) or divides a single fluid
supply into several outlet streams (distribution
manifold).
mechanical imbalance A condition that can result from a mechanical or
force imbalance. Mechanical imbalance occurs
when there is more weight on one side of a
centerline of a rotor than on the other. Force
imbalance can result when there is an imbalance
of the centripetal forces generated by rotation or
when there is an imbalance between the lift
generated by the rotor and gravity.
mechanism Any physical or mental process by which a
result is produced.

meggering Testing technique that can be used to measure
the cause-and-effect relationship between
variables in electric motors.
meshing Engagement or working contact of teeth of gears
or of a gear and a rack.
methodology A system of methods.
mixer A device used to cause intermingling of
different materials (liquid, gas, solid) to produce
a homogeneous mixture.
multichannel analysis Analysis based on data acquired simultaneously
from multiple measurement points.

noise, white Random noise that has a constant energy per
unit bandwidth at every frequency in the range
of interest.
normal event An event that is expected to occur.
oblique Having a slanted direction or position at an
angle that is neither a right angle nor a multiple
of a right angle.
