-
What is the moment of inertia of a rectangular cross section with respect to its base?
-
What is the parallel axis theorem?
The MOI wrt any given axis equals the MOI wrt the parallel axis through the centroid plus Ad 2.

What equation calculates rotational kinetic energy?
 - where I is the mass moment of inertia about the rotational axis.
-
What are the two expressions for radius of gyration?
- The radius of gyration is the distance (r, k) where all the (area, mass) would be located and give the same moment of inertia (I).
