    what is radius of gyration? How this is practically applied ? Any application example website?

    Given an object of mass m and arbitrary shape, its radius of gyration with respect to a fixed axis is the number [tex]r_{g}[/tex] so that the moment of inertia "I" of that object with respect to that axis can be written:
    Assuming you've got a way to measure applied torque and angular acceleration, the object's radius of gyration can be determined experimentally.

    any application in practical?

    Columns, it is the determining factor for Euler buckling.
