Now the circumferences of these two circles have the same relative lengths as their radii do, and since the lever does not bend, the weight can have a velocity only -^^ or ^^ as great as that of the power, and since the power is ten and its velocity twenty-nine times that of the weight, its momentum must be 10x29=290; and this being true, the weight,
