Gyration tensor

In physics, the gyration tensor is a tensor that describes the second moments of position of a collection of particles where is the Cartesian coordinate of the position vector of the particle. The origin of the coordinate system has been chosen such that i.e. in the system of the center of mass . Where Another definition, which is mathematically identical but gives an alternative calculation method, is: Therefore, the x-y component of the gyration tensor for particles in Cartesian coordinates would be: In the continuum limit, where represents the number density of particles at position . Although they have different units, the gyration tensor is related to the moment of inertia tensor. The key difference is that the particle positions are weighted by mass in the inertia tensor, whereas the gyration tensor depends only on the particle positions; mass plays no role in defining the gyration tensor.

Understanding the Area Moment of Inertia

The area moment of inertia (also called the second moment of area) defines the resistance of a cross-section to bending, due to the shape of the cross-section. It is a key parameter for the analysis of beams and columns. In this video I take a detailed look at the area moment of inertia,
