Determination of the numerical value of the gravitational constant in the case of a complicated form of interacting bodies

An example of extending the functionality of methods for calculating the gravitational constant for the spherical shape of interacting bodies is presented. The results that were obtained using an apparatus in which the working body is in the form of quartz box are analyzed. A bad choice of the form and material of the working medium for a torsion balance in a vacuum chamber with non-equilibrium flows led to a systematic measurement error.
