Radius of Gyration is the root mean square distance of various particles of the body from the axis of rotation. Here, we will study what radius of gyration is and its relationship with moment of inertia.
May 27, 2024 · Radius of Gyration is the root mean square distance of the particles of the body from the given axis. This article will cover radius of gyration, its derivation, and its formulas for different bodies.
The radius of gyration is the distance from the centroidal axis to a point where the total area of the shape is assumed to be focused which gives the same moment of inertia as that of the original shape. Mathematically it can be expressed as, I I = Moment of inertia of focused mass. I I = K2 K 2.A. Where, K = Radius of gyration.
What is the Radius of Gyration? The radius of gyration or gyradius of a body is always about an axis of rotation. It is characterized as the spiral distance to a point which would have a moment of inertia. The radius of gyration is a geometric property of a rigid body. For example, the centre of mass.
The radius of gyration or gyradius of a body about the 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 there.
The radius of gyration is the distance from an axis of a body to the point in the body whose moment of inertia is equal to the moment of inertia of the entire body.
Jul 28, 2023 · The radius of gyration is used to study the behavior of various structures under compression along an axis. It is used to predict buckling in beams and rods. In structural engineering, the radius of gyration is used to estimate the stiffness of a column.
