  1. Eccentric

    In mechanical engineering, an eccentric is a circular disk solidly fixed to a rotating axle with its centre offset from that of the axle. It is most often employed in steam engines and used to convert rotary into linear reciprocating motion in order to drive a sliding valve or a pump ram. In order to do so an eccentric usually has a groove at its circumference around which is closely fitted a circular collar attached to which an eccentric rod is suspended in such a way that its other end can impart the required reciprocating motion. A return crank fulfils the same function except that it can only work at the end of an axle or on the outside of a wheel whereas an eccentric can also be fitted to the body of the axle between the wheels. Unlike a cam, which also converts rotary into linear motion at almost any rate of acceleration and deceleration, an eccentric or return crank can only impart simple harmonic motion.

Chambers 20th Century Dictionary

    -al, ek-sen′trik, -al, adj. departing from the centre: not having the same centre as another, said of circles: out of the usual course: not conforming to common rules: odd.—n. Eccen′tric, a circle not having the same centre as another: (mech.) a contrivance for taking an alternating rectilinear motion from a revolving shaft: an eccentric fellow.—adv. Eccen′trically.—n. Eccentric′ity, the distance of the centre of a planet's orbit from the centre of the sun: singularity of conduct: oddness. [Fr.,—Low L. eccentricus—Gr. ek, out of, kentron, centre.]

Military Dictionary and Gazetteer

  1. eccentric

    A device applied to the truck wheels of top carriages and beds of mortars in sea-coast artillery to give either rolling or sliding friction at will. The wheels turn on axle-arms which project eccentrically from the ends of an axle passing through both cheeks; when the axle is turned the axle-arms carry the wheels up or down; when at the lowest point the weight of the carriage is borne by the wheels, and the system moves on rolling friction; the wheels are then said to be in gear; when out of gear, or at their highest points, the wheels do not touch the rails or platform plates, but the cheeks rest on them, and the carriage moves upon sliding friction. A similar device is attached to the chassis near the pintle to enable it to be readily traversed when in gear, and give it stability when out of gear.

Examples of eccentric in a Sentence

  2. Michael J. Gelb:

    Crazy people who are productive are geniuses. Crazy people who are rich are eccentric. Crazy people who are neither productive nor rich are just plain crazy.

    I think Qaasim Middleton, who we used it on, kept delivering for the next few weeks and kept getting through, so I think it was a good use of the save. The eccentric Cook was a favorite, although maybe not the singer many predicted to go all the way. Some thought her performance of My Funny Valentine was not her best, and she wound up in the bottom two with Rayvon Owen. In the end, the Twitter save element saved Rayvon Owen, for a third straight week. I think hes in a dangerous place now.

  5. Maria Moldes:

    They are bizarre, exaggerated, eccentric.
