...bars of thin iron ?" And when we consider that all the mechanical powers may be reduced to the lentr, the wheel and axle, the pulley, the inclined plane, the wedge and the jereto, how astonishing are the forces exerted, and the effects produced, by their various combinations... | |

...denominated Statics will be the subject of the present inquiry. The mechanical powers are six: the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw. The lever is the most powerful, because there is no limit to the difference of intensity in force of... | |

...change the direction of any force. The mechanical powers are usually considered six in number ; — the Lever, the Wheel and Axle, the Pulley, the Inclined Plane, the Wedge, and the Screw. The first three, when in a state of equilibrium, may be reduced to the lever ; and the three last,... | |

...mechanical powers now, mamma ?" " Yes, I believe you may refer all sorts of mechanical contrivances to the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw, either separately or combined." "I will notice, mamma, and then whether I am in the town or the country,... | |

...conceptions of the nature of power, and what it is to which we apply that term. For instance, we speak of the Lever, the Wheel and Axle, the Pulley, the Inclined Plane, the Wedge and the Screw as " Mechanical Powers." And although no one, who stops to think carefully upon the subject, supposes... | |
