...The parts of the lever, from the fulcrum to the weight and power, are called the arms of the lever. An equilibrium is produced in all the levers when...distance from the fulcrum is equal to the product multiplied by its distance from the fulcrum ; that is, the weight is to the power, as the distance... | |
