 (Vortex force) Use Cavendish torsion balance measuring gravity tangential component (Vortex force) zhuyonghuan Abstract According to the prediction of general relativity, a rotating object will drag the space-time along with it. This is called frame-dragging (Lense-Thirring effect) After a long inquiry, In 2001 by Cavendish torsion balance to measure not only have gravitation to the weight of law (that is gravity), and the existence of the tangential component (vortex force), and arrive at the formula. Key words: Cavendish torsion balance vortex force Gravitational constant G = π ^ 2 * b * 2 * ds / M * L * T ^ 2 Where: M: quality of the big shot put T: torsion balance vibration cycle.
