TM 612 Flywheel Apparatus
Education / GUNT Hamburg / Engineering Mechanics and Machine Elements / Dynamics /

Using the TM 612, basic experiments on uniformly accelerated angular motion can be performed. A flywheel mounted in ball bearings is placed in motion by a weight attached to a pulley. The inertia of the flywheel can be determined from the fall time of the weight.

The unit is intended for wall mounting. Due to the clear, robust construction the unit is excellently suited to student experiments.
