...point, practically available at another, are called the mechanical powers. Amongst them may be reckoned the Lever, the Wheel and Axle, the Pulley, the Inclined Plane, the Wedge, and the Screw. It will be seen, however, that these six may be reduced in principle to two, the Lever and the Inclined... | |
