Eccentric movement

from Wikipedia, the free encyclopedia
approximate eccentric movement of a connecting rod

The eccentric movement (also revolution ) is a movement of a body , the points of which all rotate with the same angular velocity on circles of the same size around different parallel axes. In contrast to the rotation , the body does not change its orientation in space. It is a pure translation .

examples are

  • the scratches that are produced by circular sanding ,
  • the movement of the hand of an organ grinder ,
  • approximately the movement of a connecting rod (additional small turning back and forth)
  • the movement of the earth around its center of gravity common to the moon ( barycenter ) (see tides ).
