Most Versatile Rotational System Available

Features

The differences in moments of inertia are large enough to be sensed by the student when rotating the system by hand.  Hardware fittings support mounting sensors for computer monitoring of angular position, velocity, and acceleration. A motorized rotational drive can be attached to the system to rotate the platform at any selected constant velocity.

• Four kilogram cast iron base for stability
• Dual ball bearings
• Precision stainless steel shaft

Enable Computer-Based Data Acquisition

It is easy to implement computer-based data collection and analysis of rotational motion data with the Complete Rotational System with either a Rotary Motion Sensor or a Photogate. 

• The Rotary Motion Sensor (CI-6538 or PS-2120) mounts to the base with an "A" Adapter (CI-6690) and measures both angular velocity and direction
• The Photogate Head (ME-9498A) mounts directly to the rotating platform base to measures angular velocity (the photogate does not determine direction).
• The Computer Based Centripetal Force Accessory (ME-8089) combined with a force sensor enables dynamic measurements of centripetal force.
