Attaching Accessories to the Wireless Rotary Motion Sensor
Using the Disk from the Disk and Ring Set
(ME-3419)
For rotational inertia experiments, mount the
Wireless Rotary Motion Sensor with the Disk
horizontal. The underside of the Disk has a
square shaped indent that fits the
square-shaped top of the 3-Step Pulley. Mount
a Super Pulley with Clamp (ME-9448B) on the
platform at the side of the sensor. To provide a
known torque, wrap a string around one of the
steps of the 3-step Pulley. Arrange the end of
the string over the Super Pulley and attach a
hanging mass.
Adjust the Super Pulley on the platform so that
the string is tangent to the step on the 3-step
Pulley on the sensor.
Perform a conservation of angular momentum
experiment by dropping a second Disk onto the
first Disk as it is rotating. Alternately, attach one
of the Ring Alignment Devices to the first Disk
and then drop the Ring onto the first disk.(See
the suggested experiments.)
