Coulomb's Torsion Balance
Check us out at www.tutorvista.com The torsion balance, also called torsion pendulum, is a scientific apparatus for measuring very weak forces, usually credited to Charles-Augustin de Coulomb, who invented it in 1777, but independently invented by John Michell sometime before 1783 Its most well-known uses were by Coulomb to measure the electrostatic force between charges to establish Coulomb's Law, and by Henry Cavendish in 1798 in the Cavendish experiment to measure the gravitational force between two masses to calculate the density of the Earth, leading later to a value for the gravitational constant. The torsion balance consists of a bar suspended from its middle by a thin fiber. The fiber acts as a very weak torsion spring. If an unknown force is applied at right angles to the ends of the bar, the bar will rotate, twisting the fiber, until it reaches an equilibrium where the twisting force or torque of the fiber balances the applied force. Then the magnitude of the force is proportional to the angle of the bar. The sensitivity of the instrument comes from the weak spring constant of the fiber, so a very weak force causes a large rotation of the bar. In Coulomb's experiment, the torsion balance was an insulating rod with a metal-coated ball attached to one end, suspended by a silk thread. The ball was charged with a known charge of static electricity, and a second charged ball of the same polarity was brought near it. The two charged balls repelled one another <b>...</b>

How to Make a Torsion Catapult - Table top size Mangonel
This is a great little catapult that uses torsion from twisted rope or string. It is more accurate to the types of catapults used in the middle ages because they didn't have rubber bands back then but they did have rope. The rope can generate enormous force that is used to hurl a projectile. If you are having trouble wrapping the rope or string I have a video that shows you exactly how to do it here: www.youtube.com This type of catapult is more specifically called a Mangonel. Lots more catapult stuff on my website: www.StormTheCastle.com and a web based tutorial with complete plans, instructions and pictures for this catapult is coming soon.

"The Wyvern" a 3 foot Torsion Catapult built in 23 Minutes
I built this catapult in 23 minutes. I tried to do it in ten minutes. I will be posting complete plans for this torsion catapult on my website. You just need some rope and a few pieces of wood. I call this catapult "The Wyvern". When you use twisted rope like this the catapult is called a Mangonel.

Torsion Physics
Rolling your eyes at those crazy new age, peace, love, hippies that talk to aliens and angels and are so annoyingly happy all the time? Left brain is explaining now what the right brain knew all along. Left brain had to give love and consciousness a fancy name like quantum reality and use quantum physics to do it. Sounds pretty right brained to me! Whatever.

THE ONLY REASON WHY YOU WON'T ACCEPT IT AS TRUTH IS, BECAUSE YOU ARE AFRAID OF TAKING FULL RESPONSIBILITY FOR YOU LIFE.

H3 Torsion Bar Lift Video Walkthrough
Step 1: Jack front end up with floor jack (make sure you are on level ground) Step 2: Locate and adjust torsion nut 2.5 turns clockwise on each side (clockwise will give increased height) Step 3: Lower the front end and drive around. Pump the brakes some to let everything settle/work in Step 4: Take measurements for back and front wheels from the center of the hub cap to the lip of the fender (you want to bring the front wheel measurement up to equal the back wheel measurement) Repeat steps 1-4 adjusting the amount of turns you do on the torsion nuts as needed to have the back height equal the front height Step 5: Get a front wheel alignment! Step 6: **OPTIONAL** Get and install bilstein fron shocks and bump stops h3 package from www.trailduty.com (cheapest I've seen) to increase ride and comfort

Cavendish's torsion-bar experiment HD
The experiment was performed in 179798 by the English scientist Henry Cavendish. He followed a method prescribed and used apparatus built by his countryman, the geologist John Michell, who had died in 1793. The apparatus employed was a torsion balance, essentially a stretched wire supporting spherical weights. Attraction between pairs of weights caused the wire to twist slightly, which thus allowed the first calculation of the value of the gravitational constant G. The experiment was popularly known as weighing the Earth because determination of G permitted calculation of the Earth's mass. physics-animations.com

TORSION Field Visualization Helper HD-720p
A Wheel within a wheel, a most mysterious motive appearing in all sorts of ancient scriptures, creating an EM Field upon which a Torsion Field is placed to release the gravity anchor. Essentially two bands of light moving in opposite directions drilling into the Omni Field as it is performed in a discipline based on ancient teachings. For the Initiate, this can be a very hard visual to focus on, that's why I created this helper for my friends. music credits: www.reverbnation.com
