Eccentric movement
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 ).
