TM 162 Bifilar / Trifilar Suspension Apparatus
Education / GUNT Hamburg / Engineering Mechanics and Machine Elements / Dynamics /

The model permits oscillations on pendulums with bifilar or trifilar suspension to be investigated. For this purpose a bar, a cylinder, or a hollow cylinder made of galvanised steel can be hung from a wall mounted carrier plate made of aluminium and placed in oscillation. The bodies used in the experiments have strong steel hooks for attachment to the suspension cords. The length of the cords can be rapidly changed and securely fixed using clamping wheels. The beam can oscillate, by translation, in the plane of suspension like an ideal mathematical pendulum. The cylinder and the circular ring work as rotary pendulums.
