The Flywheel Apparatus ProDynami - 1201 demonstrates the working principle of a flywheel and its role in storing and delivering rotational energy. This Fly Wheel Apparatus consists of a steel flywheel mounted on a ball bearing shaft, fixed to an anodised aluminium base plate. Students add weights to a hanger connected via cord to determine the moment of inertia of the flywheel. The flywheel has a diameter of 300mm, a mass of 23kg, and a mass moment of inertia of 0.25kgm². It is also used to verify the laws of gyroscopic precession.

Construction and Design
The Flywheel Apparatus ProDynami - 1201 features a flywheel mounted on a shaft. The shaft is mounted on ball bearings. The shaft also functions as a drive pulley. The entire structure is fixed to a base plate. The base plate is made of anodised aluminium. A cord is wound on the axle. The cord carries dead weights and a hanger. This Fly Wheel Apparatus allows students to add weights on the hanger to calculate flywheel inertia.
Scope of Delivery
Q: What is the Flywheel Apparatus ProDynami - 1201 used for?
