...to CA, the Diftance of the Direction of the Power from the Fulcrum, the Power will be to the Weight, as the Velocity of the Weight to the Velocity of the Power; the Momentum therefore of the Power [by Cor. 3. Theor. 3.] will be equal to the Momentum of the Weight:... | |

...confidering one of them as the power and the other as the weight, the power will be to the weight, as the velocity of the weight to the velocity of the power. Therefore in this, as in all mechanical engines, when a finall power raifes a great weight, the velocity... | |

...descent. OF THE LEVER OR STEELYARD. 86. It is a principle in mechanicks, that the power is to the weight, as the velocity of the weight, to the velocity of the power. Therefore, to find what weight may be raised or balanced by any given power, say ; , As the distance... | |
