And that's it! Watching a swinging sticks sculpture is strangely mesmerizing, like watching a log fire. But it's also deceptive. It appears that the two arms swing in simple circles. While this is true of the primary arm, the secondary can follow amazingly convoluted paths.
To capture some of them, I covered the back of a swinging sticks kinetic sculpture with black paper and photographed it with a camera lens held open for five seconds.
In the following images, the large, faint, circular disc is created by the primary arm sweeping in simple circles. The more complex and brighter patterns were made by the smaller secondary arm:. The Swinging Sticks almost seem to defy the laws of physics and gravity. It is the double pendulum kinetic energy perpetual motion desk sculpture. Terms and Conditions. Contact Us. Close x. However, one of the key principles in physics also points out that moving electrons generate magnetic fields. The generated magnetic field is the driving force of the entire sculpture.
The Swinging Sticks contains measuring sensors that can perform various functions. Two of the sensors are used to measure the speed of the rotating rod.
The middle electric coil is used to adjust the speed faster or slower , according to the speed judged by the 2 sensors. The arm of the Swinging Sticks has a powerful neodymium magnet built in. As long as the magnetic field is generated, the process will be repeated. The position of the magnet, Coil and Distance in addition to the weights must be extremely precise to avoid wasting movement or power. In physics and mathematics, in the area of dynamical systems, a double pendulum is a pendulum with another pendulum attached to its end, and is a simple physical system that exhibits rich dynamic behavior with a strong sensitivity to initial conditions.
The Swinging Sticks contains three coils that serve various functions. Two of the electrical coils are involved with measuring the speed of the rotating sticks.
The middle electrical coil is used to adjust the speed either faster or slower depending on the speed judged by the first and last coils. Built into the arms of the Swinging Sticks are powerful neodym magnets. When these magnets pass through the magnetic field generated by the electrical coils, they are repulsed and get a "boost" of kinetic energy while shooting upwards before effortlessly spinning back down.
This process repeats over and over as long as a magnetic field is generated. The position of the magnets must be extremely precise as not to waste motion or power. Conservation of energy is extremely important in the sculpture in order to provide longevity of battery life. The authentic Swinging Sticks contains state-of-the-art SFK bearings and special electrical components to reduce the amount of energy consumed.
This is why this sculpture requires 4 AA batteries, not to run a motor, because the sculpture is noiseless in its rotation but to provide an electric current. As long as there are batteries, this sculpture will run forever, endlessly spinning in a generated electromagnetic field.
The Swinging Sticks are governed by a series of calculus equations in physics related to double pendulums.
