...indeed, are often employed separately, are called Mechanical Powers. Z. Of these we usually reckon six : viz. the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw. To these, however, is sometimes added the funicular machine, being that which is formed by the action... | |

...Powers are the most simple of mechanical applications to increase force and overcome resistance. They are usually accounted six in number, viz. The Lever...The Inclined Plane — The Wedge — and the Screw. LEVER. To make the principle easily understood, we must suppose the lever an inflexible rod without... | |
