Out of the whole, or a part, of these, it will be found that every mechanical engine, or piece of machinery,... | |

...constitutes the science of mechanics. The mechanical powers are usually divided into six classes ; the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw ; but all these are reducible to two, the lever and the inclined plane Some, however, regard the pulley... | |
