General Setup Options
1) Mounting the Rotary Motion Sensor (RMS)
a) Mounting the RMS on a Support Rod
The Rotary Motion Sensor can be mounted on a support rod using the
supplied rod clamp. The rod clamp can be mounted in three different
locations on the Rotary Motion Sensor: at the end opposite the cable
and on either side of the case. A Phillips screwdriver is required to
remove the two screws that hold the rod clamp on the Rotary Motion
Sensor case.
It is possible to mount the RMS horizontally on a support rod, with the
3-step Pulley facing up or vertically, with the pulley facing forward.

Note: When setting
up the rotational
inertia experiment
with the thin rod for
the mini-rotational
accessory, the
Rotary Motion Sen-
sor must be
mounted at the top
of the support rod,
so that the support
rod does not inter-
fere with the rota-
tion of the thin rod.
