Attaching Accessories to the Rotary Motion Sensor (RMS)
a) Attaching the Mini-Rotational Accessory to the RMS
To attach the thin rod to the RMS, orient the 3-step 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.
The rod can be used for two purposes:
• The center of the rod can be attached to the RMS rotating shaft and
used with the point masses to find the rotational inertia of point
masses.
