Link Inertial Tensor Convention

The components of tensors of degree two can be assembled into a matrix. For the inertia tensor this matrix is given by,

It is common in rigid body mechanics to use notation that explicitly identifies the x, y, and z axes, such as Ixx and Ixy, for the components of the inertia tensor.
