Run-out or runout is an inaccuracy of rotating mechanical systems, specifically that the tool or shaft does not rotate exactly in line with the main axis. For example; when drilling , run-out will result in a larger hole than the drill's nominal diameter due to the drill being rotated eccentrically (off axis instead of in line).
Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof. GD&T is used to define the nominal (theoretically perfect ...
The term GD&T is likely the outgrowth of a major proponent, Lowell Foster, who wrote introductory texts called Geometrics, but it is just as likely a marketing term developed by one of the huge number of trainer/consultants in the field of 'Y14.5 application.
A datum reference or just datum (plural: datums [Note 1]) is some important part of an object—such as a point, line, plane, hole, set of holes, or pair of surfaces—that serves as a reference in defining the geometry of the object and (often) in measuring aspects of the actual geometry to assess how closely they match with the nominal value, which may be an ideal, standard, average, or ...
A runout may include any of the following: Runout (climbing), a section of a rock climbing route with a long gap between points of protection; Run-out, an inaccuracy of rotating mechanical systems, specifically when a tool or shaft does not rotate exactly in line with the main axis. Run out, a method of dismissal in the sport of cricket.
The 10mm area-of-interest also means that bulge measurement is limited to a small portion of the tire. Capacitive sensors employ void filtering to remove the effect of the voids between the tread lugs in radial runout measurement, and letter filtering to remove the effect of raised letters and ornamentation on the sidewall.

In 1965, 30 states administered the first FE exam. The FE tests knowledge of what college graduates should have mastered during school. In 1966, a national uniform PE exam was offered. [1] As of 2014, the FE and FS exams are offered only via Computer Based Testing (CBT). The exam consists of 110 questions and is given during a 6-hour session ...
