Question

define radious of gyration

Answer 1

Radius of gyration or gyradius of a body about an axis of rotation is defined as the radial distance to a point which would have a moment of inertia the same as the body's actual distribution of mass, if the total mass of the body were concentrated.

Answer 2

Answer:

The distance from an axis at which the mass of the body maybe assumed to be concentrated and at which the moment of inertia will be equal to the moment of inertia of the actual mass about the axis equal to the square root of the quotient of the moment of inertia and mass
