Animation of an anchor escapement, one of the most common escapements used in pendulum clocks The escapement is a mechanical linkage that converts the force from the clock's wheel train into impulses that keep the pendulum swinging back and forth.
Animation showing operation of an anchor escapement The anchor and escape wheel of a late 19th-century clock. The plate that normally holds the front end of the pinions has been removed for clarity. The pendulum is behind the back plate. In horology, the anchor escapement is a type of escapement used in pendulum clocks.
Animation of an anchor escapement, widely used in pendulum clocks. An escapement is a mechanical linkage in mechanical watches and clocks that gives impulses to the timekeeping element and periodically releases the gear train to move forward, advancing the clock's hands.
"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.
Shortt clocks kept time with two pendulums, a primary pendulum swinging in a vacuum tank and a secondary pendulum in a separate clock, which was synchronized to the primary by electro-mechanical means. The secondary pendulum was attached to the timekeeping mechanisms of the clock, leaving the primary pendulum virtually free of external ...
The second verge pendulum clock built by Christiaan Huygens, inventor of the pendulum clock, 1673. Huygens claimed an accuracy of 10 seconds per day. In a pendulum clock, the verge escapement is turned 90 degrees so that the crown wheel faces up (top).
The animation can be correct concerning the trajectory. It is a matter of the initial boundary conditions of the equations of motion. And concerning the exaggerated angular velocity it has to be this way to illustrate the motion. A clock won't do as the clock depends on the latitude. -- Slaunger 19:26, 2 February 2008 (UTC)
The animations below depict the motion of a simple (frictionless) pendulum with increasing amounts of initial displacement of the bob, or equivalently increasing initial velocity. The small graph above each pendulum is the corresponding phase plane diagram; the horizontal axis is displacement and the vertical axis is velocity. With a large ...
