23. Perpetual Motion
The
lever type
The central
weights, A, each weigh one-fourth more than the weights, B, at the
extremities of the arms. The two sets of weights are connected pairs,
each pair being joined by a lever, link, and bell crank C. The action
of gravity in the central weights compels the sliding weights at the
ends of the arms to assume the positions shown in the engraving.
Had this inventor applied a little
mathematical calculation to the
verification of the truth or falsity of the principle of his device, he
might easily have proved that it was a perfect balance, and saved
himself both trouble and expense. The leverage of the outside is
exactly counteracted by the leverage of the inside weights.
