B-1. Calculate the moment of inertia of a uniform square plate of mass M and side L about one of its diagonals, with the help of its moment of inertia about its centre of mass.

B-2. A uniform triangular mass M whose vertices are ABC has lengths $\mathcal{l},\frac{\mathcal{l}}{\sqrt{2}},\frac{\mathcal{l}}{\sqrt{2}}$ as shown in figure. Find the moment of inertia of the plate about an axis passing through point B and perpendicular to the plane of the plate.

B-3 Find the moment of inertia of a uniform half-disc about an axis perpendicular to the plane and passing through its centre of mass. Mass of this disc is M and radius is R.

B-4 Calculate the radius of gyration of a uniform circular disk of radius r and thickness t about a line perpendicular to the plane of this disk and tangent to th disk.
