This Maxwell wheel apparatus is constructed with a heavy wooden base and a solid metal flywheel measuring 3.5" in diameter. The apparatus stands 22" tall. The flywheel cord can be easily adjusted from the top to fine-tune results. To operate, wind the cords around the flywheel axle and release. The wheel unwinds and then recoils due to momentum. The flywheel can also be adjusted off-center to examine the effects of asymmetric loading. Oscillation runs for an extended period due to the adjustability of the apparatus, eventually coming to rest as momentum is lost to friction. The apparatus demonstrates conservation of energy, rotational inertia, and energy transfer between potential and kinetic forms.
