Description
A precision measurement of the gravitational constant G has been made using a beam balance. Special attention has been given to determining the calibration, the effect of a possible nonlinearity of the balance and the zero-point variation of the balance. The equipment, the measurements, and the analysis are described in detail. The value obtained for G is 6.674 252(109)(54)x10-11 m3 kg-1 s-2. The relative statistical and systematic uncertainties of this result are 16.3x10-6 and 8.1x10-6, respectively
