The Pendulum is a stylised educational model, an interactive study guide of the mechanism, designated for learning its essentials and principles of operation. Its working principle is based on the model’s constant amplitude oscillation under the force of gravity (weight) and potential energy (tension force) of the rubber band.
The rubber band powers the mechanism of the model and compensates for the pendulum’s oscillations’ kinetic energy loss.
The mechanism is animated by means of gear unit with a windup wheel.
The model has an anchor escapement controlling the frequency of oscillations, a weight, a scape-wheel, gearing, rubber band, ratchet and pawl reducing operation error.
The model has several means of controlling the frequency of oscillations: the weight of the pendulum bob, the vertical position of the weight on the pendulum and the tension of the rubber band.
