When a vehicle is accelerating, the loads on one of the wheels on the driving axle are estimated as shown below.
The mass of the wheel is 18,7 kg and its diameter is 0,6 m. It has a radius of gyration of 0,23 m around its centre of mass, G.
It is known that while the vehicle is accelerating, the wheels roll without slipping. Determine the mass moment of inertia of the wheel about an axis passing through the
instantaneous centre of zero velocity of the wheel.

A subassembly for a model airplane is fabricated from three pieces of 1.5-mm plywood. Neglecting the mass of the adhesive used to assemble the three pieces, determine the mass moment of inertia of the subassembly with respect to each of the coordinate axes. (The density of the plywood is 780 kg/m3.)
Consider a cube with mass m and side a. (a) Show that the ellipsoid of inertia at the center of the cube is a sphere, and use this property to determine the moment of inertia of the cube with respect to one of its diagonals. (b) Show that the ellipsoid of inertia at one of the corners of the cube is an ellipsoid of revolution, and determine the principal moments of inertia of the cube at that point.
