RADIUS OF GYRATION APPLICATIONS
The concepts of rigid body or particle dynamics are used in engineering when motion is involved. This can be motion of a fluid element, a controller such as a flap or landing gear mechanism, and trajectories of vehicles.
It is important that the principles of dynamics are well understood by engineers. An engineering problem can be thought of as a word problem, similar to word problems solved in mathematics. Dynamics provides the basics by which the equations of motions that govern the problem can be derived and applied.
The radius of gyration is found for rotating bodies. Known values of the radius of gyration for a particular body geometry can be used to solve for the moments of inertia, which can be used to determine more information about the rotating body, such as velocity, acceleration, moments, and so on.
