APPARATUS
wilberforce pendulum with masses
202-17-E6
DESCRIPTION
The frequencies of the torsional and
vertical
translational modes of the mass on the spring can be adjusted, by
varying
the mass, to have an integer ratio. Then the oscillator cycles
through
the two modes.
NOTES
Coupling between the two modes works
best
with m = 6 g.
