Students demonstrate chaotic motion to you every day . . . now you can easily and dramatically demonstrate it back with another one of Bruce Yeany's clever devices. -- This pendulum can be used to show both simple harmonic motion and chaotic motion. By loosening one of the arms you can create two pendulums in one with different periods; by loosening both arms you can create three pendulums in one. -- To demonstrate resonance, simply apply a small amount of energy to the multiple pendulums. -- When more energy is applied, so many variable forces act upon the multiple pendulums that the motion clearly becomes unpredictable, or chaotic. -- Includes: chaotic pendulum, C-clamp, nails and complete instructions for demonstrations and explanations. |
