Radius of gyration: Is defined as the imaginary distance from

Radius of Gyration is defined as the imaginary distance from the centroid at which the area of cross-section is imagined to be focused at a point in order to obtain the same moment of inertia. In this article, we will learn about the radius of gyration in physics and its applications. We will also calculate its value for a thin rod and solid sphere. First, let’s start with the definition. Radius of Gyration is an imaginary distance from the axis of rotation to a point where the total mass of the body is concentrated so that the moment of inertia about the axis remains the same. It basically relates the moment of inertia about the particular axis to the area of rotation. Learn what radius of gyration is and how to calculate it for different applications in mechanics and engineering. Find out the difference between radius of gyration and radius of rotation, and see examples and derivations. GeeksforGeeks | A computer science portal for geeks
