In a bifilar suspension, the pendulum body is suspended over two threads. The pendulum body oscillates in a plane purely translationally without rotation. This kind of pendulum can be considered as a mathematical pendulum. In a trifilar suspension with three threads, the pendulum body is set in a torsional vibration. The torsional vibration can be used to determine the moment of inertia by experiment.
