it will be shown that the body is lighter during
the downward acceleration and interest the body of flywheel
is suspended under a kitchen scale at rest the scale is at
equilibrium after brief excitation it oscillates around this equilibrium position I
when the flywheel is released it accelerates downwards with the string unwinding from the axle the scale
shows a decrease in weight when the
flywheel which is the end of the string and
begins its upward climb the
jerk must be caught afterwards the scale oscillates around an equilibrium position indicating a smaller weight and this remains unaltered during the subsequent downward
motion the In order to avoid this
disturbing oscillation a small weight
is placed on the right hand so the scale will be in equilibrium during the downward motion addressed the scale then indicates to larger weight
upon releasing the flywheel with the scale initially held in the equilibrium
position the scale indicates equilibrium during the subsequent
downward upward and downward
motion note even during the upward
motion the Wheel accelerates
downwards

Abstract A body that is being accelerated downward weighs less than when at rest. This is demonstrated with a flywheel on a shaft suspended on one arm of a household scale (Maxwell's disk). It is suspended on one arm of the scale with two strings which wrap around the thin shaft. When the flywheel is released, it accelerates downward, and the scale reads a reduced weight. During the subsequent rise (the flywheel still accelerating downward!) the scale again indicates a reduced weight.
