Abstract

The invention relates to a process and to a device for determining the centre of gravity and the inertial tensor of a body using a torsional pendulum. The invention makes use of the change in the moment of inertia when the body is moved relative to the axis of rotation. Knowing the positions of the different axes of rotation and using Steiner's theorem, the centre of gravity of the body and the moments of inertia through this centre of gravity can be calculated. The six independent inertial tensor elements can be determined by carrying out measurements in six different directions.
