1. Description
The SW Wilberforce pendulum set has every-
thing you need to build a Wilberforce pendulum
in a space-saving table-top set-up.
It consists of a coil spring and an adjustable
rotating body, allowing the moment of inertia to
be fine-tuned in order to investigate coupled
translation and rotation forces by means of the
Wilberforce experiment.
A spring module makes it possible to connect
the pendulum to the dynamic force sensors from
the SW sensors set in order to record and ana-
lyse oscillations with two degrees of freedom by
means of an oscilloscope.
The wire hook is designed to stabilise the axial
rotation motion and guarantees non-slip cou-
pling of the rotating body to the spring.
