3A10.15 - Large Pendulum Hung from Ceiling
Demonstrate a simple pendulum.
InstructionsA large brightly painted lead ball is hung on a light steel cable fastened to a beam on the catwalk. This pendulum may be used in many ways when talking about harmonic motion. The suspension consists of light wire rope with the appropriate hardware secured to both ends with safety fittings. These fittings consist of a small brass cylinder with a hole through it just large enough to pass three pieces of the wire, and securing set screws. The wire is looped through the hole and then looped back through a second time. The loops are pulled up tight and the screws tightened.
