For showing the effects of vibrations in a stretched cord and investigate the relationship
between frequency, tension and density. In addition, the presence of electrical contacts,
opened and closed by a vibrating armature, allows the apparatus to be used as
high-speed changeover switch in. Composed of a thin steel rod mounted on a in a
clamp formed by a pair of 4 mm terminal sockets, so that its free length may be adjusted
as desired.
An AC energizing coil surrounds the armature and a permanent magnet provides the necessary
magnetic polarization. The free end of the armature equipped with a small
bosshead and clamp serves for tying the cord and also as the moving contact when the
apparatus is operating as a changeover switch.
