6.4 Determination of acceleration due to
gravity
The periods of oscillation T
at the two points where the curves intersect and
at these points they are equal to the period of os-
cillation T
of the calibrated pendulum, i.e.

From the period duration T
for a calibrated reversible pendulum and a dis-
tance l = 0.8 m between the two fulcra, corre-
sponding to the shortened pendulum length, it is
possible to determine the acceleration due to
earth's gravity:

Note: To adjust the pendulum so that both peri-
ods of oscillation are exactly the same, it may be
necessary to turn the pendulum bob by 180°
about the vertical and mount it on the pendulum
rod that way round.

7. Storage, cleaning, and disposal
Keep the apparatus in a clean, dry, dust-free
place.
Do not use aggressive cleaning agents or sol-
vents to clean the apparatus.
In order to clean the equipment, use a soft,
damp cloth.
The packaging should be disposed of at local
recycling centres
If the equipment itself is
to be disposed of, it
must not be included
with normal household
waste. Local regula-
tions are to be obeyed.
