﻿How a pendulum clock works?
Usually there is a weight on the end of a length of wire or cord which is wrapped around a drum. The drum would turn quickly, pulled by the weight, if it wasn't for anescapement mechanism which slows the process down. Instead of a weight on a cord, I have drawn a gremlin whose weight does the same thing. If the escapement didn't stop the spoked wheel from turning,the gremlin would quickly finish on the floor if he couldn't run at an incredible speed.
The escapement mechanism consists of a pendulum with a bar fixed to the top having two teeth. The pendulum ispositioned to that the two teeth alternately swing in and out of the spoked wheel. Generally speaking, when one tooth is within the circumference of the wheel, the other isn't, although in practice itis arranged that both are within the circumference for a short time.
The result is that as the pendulum swings one way, the wheel rotates until a spoke is touching one tooth. When the pendulumswings, the tooth releases the spoke and the wheel rotates until one of the other spokes is held by the other tooth. When that tooth swings out of the way to allow the wheel to turn again, the other toothis back to stop another spoke.

¿Cómo funciona un reloj de péndulo?
Generalmente hay un peso en el extremo de un alambre o cuerda que se envuelve alrededor de un tambor. El tambor se convertiríarápidamente, arrastrado por el peso, si no fuera por un mecanismo de escape que ralentiza el proceso. En lugar de un peso en un cable, he llegado a un gremlin cuyo peso hace lo mismo. Si la fuga no sedetuvo la rueda de radios de giro, la gremlin rápidamente acabar en el suelo si no podía correr a una velocidad increíble.
El mecanismo de escape se compone de un péndulo con una barra fija a la partesuperior con dos dientes. El péndulo está en condiciones de que los dos dientes alternativamente swing dentro y fuera de la rueda de radios. En general, cuando un diente se encuentra dentro de la...
