What is the relationship between Moment of inertia and radius of gyration?

I believe it is I = mk^2 where k is radius of gyration and m is mass.


Radius of gyration of tubular steel of 60 mm diameter pipe?

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


What is meant by Radius of gyration?

It is the square root of ratio moment of inertia of the given axis to its mass.


What is formula for radius of gyration?

The formula for radius of gyration is given by (k = \sqrt{\frac{I}{m}}), where (k) is the radius of gyration, (I) is the moment of inertia of the object, and (m) is the mass of the object. Radius of gyration is the distance from the axis of rotation where the entire mass of an object is considered to be concentrated.


What is physical significance of radius of gyration?

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.


What is the radius of gyration of a flywheel in the form of a uniform cylinder of radius 0.43m?

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.


Define radius of gyration state s.i. units of moment of inertia and give its dimensions?

The Radius of Gyration of an Area about a given axis is a distance k from the axis. At this distance k an equivalent area is thought of as a line Area parallel to the original axis. The moment of inertia of this Line Area about the original axis is unchanged.


What do you know about radius of gyration?

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.


Is radius of gyration depend on mass?

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


Is radius of gyration a constant quantity?

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.


The moment of inertia of a solid cylinder is?

the moment of inertia of a solid cylinder about an axis passing through its COM and parallel to its length is mr2/2 where r is the radius.


How do you derive the moment of inertia of solid sphere?

mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
