Principle
Two small lead spheres are positioned on a beam, which is freely suspended on a thin metal wire. At the beginning the large lead spheres are positioned symmetrically opposite to the small spheres in that way that the attractive forces are eliminated. There after, the large spheres are swung so that they are close to the small spheres. As a consequence of the gravitational attracting force the beam with the small spheres now moves in a new equilibrium position, where the attractive forces are equivalent to the force of the torsion of the wire. The gravitational constant can be determined from the new equilibrium position.
