with Clamp

Introduction

The PASCO CI-6691 Mini-Rotational Accessory is de­signed for use with the PASCO CI-6538 Rotary Motion
Sensor (RMS) or the PASCO CI-6625 Rotary Motion
Sensor for ULI to perform rotational inertia, conservation
of angular momentum, and pendulum experiments. In­cluded are an aluminum disk, a steel ring, a long thin rod
and two brass masses which can be attached at any point
on the thin rod to act as point masses.

Please refer to the instruction manual supplied with the
Rotary Motion Sensor for a detailed description of ex­periments using the Mini-Rotational Accessory.

Attaching the Rod

To attach the rod to the RMS, it is necessary to turn the 3­step Pulley so the rod guides on the underside of the pul­ley face up. The 3-step Pulley and the rotating shaft on
the RMS are keyed to assemble only in one position. As­semble the apparatus as illustrated.

Mini-Rotational Accessory 012-05982B

Using the Rod

The rod can be used for two purposes:

• The center of the rod can be attached to the shaft of
the Rotary Motion Sensor and used with the point
masses to find the rotational inertia of point masses.

• The end of the rod can be attached to the Rotary Mo­tion Sensor shaft to use it as a pendulum.

Using the Disk and Ring

For rotational inertia experiments, wrap a string at­tached to a mass around the 3-step Pulley included with
the Rotary Motion Sensor. Hang the mass over the Su­per Pulley to accelerate the apparatus.

Perform a conservation of angular momentum experi­ment by dropping the ring onto the rotating disk.
