Complete Rotational System for School, Colleges and Universities Purpose.

The Complete Rotational System features a 4 kg cast iron base, dual ball bearings, and a precision stainless steel shaft. It generates sufficient moments of inertia to be easily sensed by hand during rotation. The system is ideal for experiments involving centripetal force, angular momentum, and rotational motion. Angular velocity and motorized drive can also be monitored using a computer.

Designed and manufactured by Atico Export to meet the practical requirements of modern physics laboratories and educational training facilities.

Working principle :

The system enables computer-based data collection and analysis when used with a rotary motion sensor or photogate.

• Rotary Motion Sensor : Mounts to the base using an adapter and measures angular velocity and direction.
• Photogate Head : Mounts directly to the rotating platform base to measure angular velocity.
