Paraconical pendulum

Paraconical pendulum

Characterization and experiments

The structure of the paraconical pendulum consists of a suspension with a ball permitting the pendulum to rotate within a certain angle range limit. Unlike a Foucault pendulum conceived to demonstrate the rotation of earth, a paraconical pendulum measures gravity influence of other celestial bodies, primarily Sun and Moon. The Foucault pendulum has a thread holding the bob. The paraconical pendulum has a suspension with an inflexible brass rod, holding a steel alloy bob, similar to a clock. The length of the pendulum is approx.1 meter. The plane of oscillation of a paraconical pendulum is able to turn around a longitudinal axis (change of the azimuth angle). Therefore a paraconical pendulum has one degree variance more than other pendulums.
