Σελίδα 105 - The ratio W/P between the force exerted and the force applied is called the mechanical advantage of the machine. Newton described six elementary machines to which all others may be reduced. These are the lever, the pulley, the inclined plane, the wheel and axle, the wedge and the screw. These may be reduced to three, since the wheel and axle is but a modified lever, and the screw and the wedge are but modifications of the inclined plane. In all cases, however, the law of machines holds good, viz.,...
