...and La Grange. The mechanical powers may be reduced to three, but they are usually expressed as six, the lever, the wheel and axle, the pulley, the inclined plane, the screw, and the wedge. In a single movable pulley the power gained is doubled. In a continned combination...

...help of the machine. The simple machines, usually called mechanic powers, are six in number, namely, the Lever, the "Wheel and Axle, the Pulley, the Inclined Plane, the Wedge, and the Screw. There are three kinds of levers, caused by the different situations of the weights, props, and powers....
