Foucault pendulum was made at Batumi Shota Rustaveli State University within the framework of the BSU Students Targeted Project. The author of the project is Anna Surmanidze, a third-year student in the field of Physics from the Faculty of Exact Sciences and Education, and the supervisors: Professor Nugzar Gomidze, Associate Professors Lali Kalandadze, and Izolda Jabnidze.
BSU is the first higher education institution in Georgia, where Foucault pendulum has been built.
Parameters of BSU Foucault pendulum:
Length: 17.60 meters
Mass: 38.5 kg
Geographic latitude of BSU: 〖θ=41.65〗^0.
Swinging period: T=36.144 h
Turn angle at 1 h: 〖10〗^0
Angular frequency of swinging of oscillation plane: 9.967 rad/sec
In 1851, French scientist Jean-Bernard Leon Foucault (1819-1868) built a pendulum in the Paris Pantheon, which consisted of an iron core weighing 28 kg and a wire of 67 meters in length. Foucault built the stone to demonstrate the Earth's rotational motion. The rotational motion of the earth causes the rotation of the pendulum to oscillate over time. The orbital swinging of the pendulum will return to its first state after the period T=24/sin(θ), (where θ is the geographical latitude of the experiment). It should be noted that the pendulum swinging has the highest rotational speed at poles of 15 rad/sec and minimum speed at the equator at 0 rad/sec.
