Feb 13, 2009 KentuckyFC writes Set a pendulum in motion and youll inevitably give it an ellipsoidal motion, which naturally tends to precess.Thats bad news if you want to build a Foucault Pendulum, a bob attached to a long wire swinging in a vertical plane that appears to rotate as the Earth spins beneath it.The natural precession always tends to swamp the rotation due to the Earths motion.
The Legs-Using a fine tooth saw, cut the 12 by 12 bass wood dowels to 18.5 long for the legs of the structure.

Oct 01, 2009 To build the stand, calculate the difference in lengths for adjacent pendula. Take the difference between adjacent pendula, this will form the steps on the stand so the swinging bobs are at the same level. The method of attachment is up to the builder, but the string supporting each pendulum needs to be pinched to make a definite length.

Add more weight to a pendulum to counteract friction and make the swinging last longer. Ive found that 5 lb 2 x 2 on the rotary pendulum, and 7 lb 3 x 2 on the other two works fairly well. Note that adding more weight does not generally change the frequency of the pendulum. Phase and Amplitude
Mar 18, 2012 Abigails Whimsical Sand Pendulum. On a recent trip to Israel, Abigail 10 saw a very pretty, large, and expensive sand pendulum. In it, the pendulum was able to swing, while at the same time, the sand pan was able to rotate freely. We applied our motto Why buy it if we can MAKE it.
Jun 20, 2016 This is a sand pendulum I made the base, and arm out of Myrtlewood. The base is 11 and it stands 23 Tall. I turned the base, and plumb bob on the lathe, and cut out the arm with the bandsaw. I found replacement sand on Amazon I put together a Amazon store with some of the tools I use. I upload a new project video every Friday. Thank you for supporting free woodworking ...

The sand pan is a squirrel baffle with a copper pipe cap to plug the hole.
Poke a hole in the bottom of the sack with the nail. Make the hole a little larger than the tip of a pen, so the sand doesnt come out too fast. Check the rate of flow -- you should see a slow, steady stream. Adjust the size of the hole if necessary. Seal the hole with tape. Spread a garbage bag under the pendulum, so it covers the surrounding ...
Following the pendulums motion improves visual tracking skills in children, which is useful for reading and sports. As they push and pull the cup or the string, adjust the length of the string and change the volume of sand in the cup, they understand the concepts of speed, force, motion and repeated motion as well as the impact of their actions based on the sand patterns formed.
The linear nature of a recording seismograph is because it is designed to record against a time scale which is perpendicular to the movement scale. Even if movement had a stronger direction in the ground, the table and building this sand pendulum is in would

Sep 08, 2015 First he ground and polished the tip of the pendulum from the cone-shaped tip of a steel bar. The fact that the twisted texture of the steel bar mirrors the pattern it draws in the sand is a nice, visually engaging touch. Next, he soldered the cone to a thin metal bar which acts as the main arm of the pendulum.
