ideal mathematical pendulum can be demonstrated

Description:

• 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.
• The TM 162unit can be used to study pendulum swings with bifilar or trifilar suspension.
• A beam, a cylinder or a circular ring are used as pendulum bodies.
• The length of the threads can be adjusted using clamping devices.
• The moments of inertia of the pendulum body can be calculated from the measured oscillation period.
• The oscillation period can be varied by changing the thread length.
• The experimental unit is designed to be fixed to a wall.
