Note:
• In order to initiate an oscillation which is as
free as possible from disturbance, pull the
rotating body vertically down onto the base
plate and then release it.
The two calibrating weights on the rotating body
(knurled screws) need to be screwed in by an
equal amount. For a well calibrated pendulum,
the rotary and translational motions should have
identical periods. The amplitudes of both types
of oscillation pass through the point of zero am-
plitude in quick succession.
