A hand axe is created by chipping stone, frequently flint, to kind a bifacial edge, or wedge. A wedge is an easy machine that transforms lateral force and movement in the Resource right into a transverse splitting drive and motion of the workpiece.
Controllers combine sensors, logic, and actuators to keep up the efficiency of parts of the machine. Perhaps the finest recognized would be the flyball governor for a steam engine.
