SD-1.55-Simple Flywheel

A steel disc Ø250mm diameter and 30mm thick is mounted on a shaft running in precision bearings housed in a substantial wall bracket. A mark on the flywheel and a pointer on the bracket enables the revolutions to be counted and timed with the stop watch supplied. A cord, load hanger and set of weights are provided to start the flywheel rotating. From the timings of a known number of revolutions, students can then verify the experimental capabilities of the apparatus.
