Stringless Pendulum

ARCO Stringless Pendulum demonstrates simple harmonic motion in a way that doesnt seem so tied down. Students will see the period of an oscillating body from a different perspective than the standard string and ball. The period of the 19mm mild steel ball can be measured, and the distance to a focal point can be calculated to compare the demonstration to a classic pendulum. Accessory: 1. 19mm Mild Steel Balls – 2Pcs Mechanical Specifications: 1. Dimensions: L (500mm) X W (20mm) X H (100mm) approx. 2. Weight: 850gms approx.
