The radius of gyration is a scalar quantity. It is a measure of the distribution of mass around an axis and quantifies how spread out the mass is from that axis of rotation.
The radius of gyration of a uniform cylinder is half of its radius, so for a cylinder with a radius of 0.43m, the radius of gyration would be 0.43m/2 = 0.215m. It is the distance from the axis of rotation where the mass of the cylinder may be concentrated without changing its moment of inertia.
Radius of gyration is the distance from the centre of gravity to the axis of rotation to which the weight of the rigid body will concentrate without altering the moment of inertia of that particular body.
No, the radius of gyration is not a constant quantity. It depends on the distribution of mass and the shape of the object. It is defined as the root-mean-square distance of the objects' parts from its center of mass.
In the context of general relativity, the stress-energy tensor describes the distribution of energy and momentum in spacetime. The scalar field, on the other hand, is a mathematical concept that represents a scalar quantity at every point in spacetime. The relationship between the stress-energy tensor and the scalar field lies in how the scalar field can contribute to the stress-energy tensor, influencing the curvature of spacetime and the gravitational field in general relativity.

I believe it is I = mk^2 where k is radius of gyration and m is mass.
Stress is tensor quantity. The stress tensor has 9 components. Each of its components has a magnitude (a scalar) and two directions associated with it.

The radius of gyration is a measure, in mechanics, of the distribution of mass in an object relative to its centre of mass or a specified axis of rotation.

i thing radius of gyration does not depend upon mass because it is the distance between reference axis and the centre of gravity.

radius of gyration = sqrt(Moment of inertia/cross section area) Regards, Sumit

Basically radius of gyration of a substance is defined as that distance from the axis of rotation from which if equivalent mass that of the substance is kept will have exactly the same moment of inertia about that axis of the substance.
