Homework Help: Gyration Problem

  1. Apr 13, 2005 #1
    As the problem states:

    Find the radii of gyration of a plane lamina in the shape of an ellipse of semimajor axis a, eccentricity E, about its major and minor axes, and about a third axis through one focus perpendicular to the plane.

    I don't know where to start because I don't understand what gyration would look like to determine what the value of a radii would refer to (in a diagram for example.)

    I'll give you a hint on how to start- look up the definition of "radius of gyration". I'll bet it's in your textbook, probably with formulas.
