摘要

A setup for measuring the gravitational constant in a university laboratory is described. The setup includes a torsion pendulum which swings under the action of gravitational attraction from test masses whose positions are made to change periodically in phase with pendulum oscillations by a special device. The gravity constant is calculated from the amplitude of steady-state oscillations. The experimental and calculation procedure is discussed and measurement errors are estimated.
