In the diploma thesis I discuss the rotation of a rigid body about a fixed axis that is not a principle axis. In the theoretical part, I take a closer look at angular momentum and the moment of inertia tensor, which I also calculate for a cuboid. I introduce the concept of principal axes, and connect these quantities with Euler's rotation equations.
In the experimental part of my thesis, I describe how I made an interactive animation in GeoGebra, which enables the user to rotate a cuboid about any axis they choose, and shows how the torque and angular momentum vectors change with time.
