Question

What is radius of gyration ​

Answer 1

Radius of gyration is defined as the distance from the axis of rotation to a point where the total mass of the body is supposed to be concentrated, so that the moment of inertia about the axis may remain the same. Simply, gyration is the distribution of the components of an object.In structural engineering the Radius of Gyration is used to describe the distribution of cross sectional area in a column around its centroidal axis. R = radius of gyration (m, mm, ft, in...) I = Area Moment Of Inertia (m4, mm4, ft4, in4 ..) A = cross sectional area (m3, mm2, ft2, in2...)

Answer 2

Answer:

Radius of gyration or gyradius of a body about an 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.
