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
