The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. If a long and heavy pendulum suspended from the high roof above a circular area is monitored over an extended period of time, its plane of oscillation appears to change ...
The oldest Foucault Pendulum in Romania is located in pavilion B of the University of Oradea. It was installed in 1964 by Prof. Coriolan Rus, the then dean of the Faculty of Mathematics - Physics. It was installed in 1964 by Prof. Coriolan Rus, the then dean of the Faculty of Mathematics - Physics.
"The Pit and the Pendulum" is a short story by American writer Edgar Allan Poe and first published in 1842 in the literary annual The Gift: A Christmas and New Year's Present for 1843. The story is about the torments endured by a prisoner of the Spanish Inquisition , though Poe skews historical facts.
Foucault published two papers in 1852, one focused on astronomy with the weight free to move on all three axes (On a new experimental demonstration of the motion of the Earth, based on the fixity of the plane of rotation) [8] and the other on mechanics with the weight free to move on only two axes (On the orientation phenomena of rotating bodies driven by a fixed axis on the Earth's surface.
While he could not observe Allais's claim that there is a diurnal periodicity in the motion of a paraconical pendulum, he did, however, write: "The most interesting result of the Mexico and Brazil experiments is the increase of rotational velocity of the pendulum oscillation plane in the direction of the Foucault effect during the eclipse.
The guillotine used in Luxembourg between 1789 and 1821. A guillotine (/ ˈ ɡ ɪ l ə t iː n / GHIL-ə-teen / ˌ ɡ ɪ l ə ˈ t iː n / GHIL-ə-TEEN / ˈ ɡ i j ə t i n / GHEE-yə-teen) [1] is an apparatus designed for efficiently carrying out executions by beheading. The device consists of a tall, upright frame with a weighted and angled ...
"Simple gravity pendulum" model assumes no friction or air resistance. A pendulum is a device made of a weight suspended from a pivot so that it can swing freely. [1] When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.
The plane of the pendulum swing does not turn with the support point and is not affected by the turning of the support point. The bob is free to swing in any direction in relation to the support (refer to a Charron chuck). For a pendulum at the pole, the plane of swing remains aligned with a star that the bob is swinging toward.
