It is the square root of ratio moment of inertia of the given axis to its mass.
What is the Radius of gyration of a round solid rod?
The radius of gyration of a solid circular rod is a measure of how its mass is distributed with respect to its axis of rotation. For a solid cylindrical rod of radius ( r ) and length ( L ), the radius of gyration ( k ) about its longitudinal axis can be calculated using the formula ( k = \sqrt{\frac{I}{m}} ), where ( I ) is the moment of inertia and ( m ) is the mass. The moment of inertia for a solid rod rotating about its longitudinal axis is ( I = \frac{1}{12} mL^2 ), leading to a radius of gyration of ( k = \frac{L}{\sqrt{12}} ).
How do you calculate radius of gyration for circular section of pile?
The radius of gyration (r_g) for a circular section of a pile can be calculated using the formula: ( r_g = \sqrt{\frac{I}{A}} ), where ( I ) is the moment of inertia of the circular section and ( A ) is its cross-sectional area. For a solid circular section, the moment of inertia is given by ( I = \frac{\pi d^4}{64} ), where ( d ) is the diameter of the pile. The cross-sectional area ( A ) is calculated as ( A = \frac{\pi d^2}{4} ). Substituting these values into the radius of gyration formula provides the desired result.

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?

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?
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.
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.
