1. Safety instructions
Caution: The pendulum is equipped with a heavy
bob and two sharp needle bearings, meaning
there is a risk of injury.
Make sure the pendulum is resting in a safe
and secure location.
The pendulum bob always needs to be se-
cured against falling by means of the knurled
screw.
When setting up the pendulum, always make
sure that both needle bearings are correctly
situated in the groove.

2. Description
The rod pendulum with angle sensor is designed
for investigating simple harmonic oscillations of a
weighted pendulum. It is also possible to investi-
gate coupled oscillations with the addition of a
second pendulum and a coupling spring.
The pendulum consists of a flat rod with a U-
shaped bracket into which two needle bearings
are screwed. There are two permanent magnets
on the inside of the bracket arms. The pendulum
fits into a bearing rod with a V-shaped groove,
which is attached to a stand rod by means of a
universal clamp. The two points of contact for the
needle bearings are indicated by circular
