Find the requested components of the inertia matrix for the compound slender bar

Question

Find the requested components of the inertia matrix for the compound slender bar shown. The bar has a linear density of 3 kg/m. (A slender bar has a moments of inertia about its short axes about its center of 1/12 M middot L2, its moment of inertia about its long axis is zero, and its products of inertia about its center are zero). A certain rigid body has an inertia matrix with components given below, (also given in matrix form). What is the body's moment of inertia if it is spun about an axis in the direction , also given below? A certain rigid body has an inertia matrix with components given below, (also given in matrix form). What is the body's angular momentum vector if it is spun with angular velocity , also given below?
