It is believed that the Egyptian pyramids were built with only three basic machines: the inclined plane, the wedge, as well as the lever. The screw, which was the final of the basic machines to be invented, first came into Mesopotamia during the Neo-Assyrian period (911-609) BC. The earliest evidence of pulleys can be traced back to Mesopotamia at the beginning of the 2nd millennium BC and the earliest evidence of Egypt as early as the Twelfth Dynasty (1991-1802 BC). The lever was also used in the shadoof water-lifting mechanism, being the first type of crane machine that was first discovered in Mesopotamia at around 3000 BC at first, and then in the earliest Egyptian technology in the year 2000 BC. Lever mechanisms first came into existence sometime between 5,000 and 5,000 BC in the Near East, where it was utilized in a basic balance scale and also for the movement of large objects in antiquated Egyptian technology. The wheel, together with the axle and wheel mechanism was developed within Mesopotamia (modern Iraq) during the 5th millennium BC. The other four simple machines were invented during the old Near East. The second oldest basic machine used was an inclined plane (ramp) and was in use since the time of prehistoric times to move large objects. The hand axe has been the first example of a wedge, the oldest of the six classical machines that is the one on which the majority of modern machines are built. Hand axes, manufactured by cutting flint into a wedge, in the hands of a man transforms the force and motion of the tool into transverse splitting and motion to the workpiece. The term engine is used as a (nearclose to) synonym both by Harris as well as later on in other languages comes from (via Old French) from Latin ingenium meaning 'ingenuity, an invention'.Īxes with a Flint are found in Winchester. Compound Machines, or Engines, are innumerable. the Ballance, Leaver, Pulley, Wheel, Wedge, and Screw. The simplest machines are generally believed to be six in number including. It is whatever can exert force sufficient to lift or stop the motion of an object. The OED determines the formal modern meaning to John Harris' Lexicon Technicum (1704) that states: The modern meaning was born from the specific application of the term to stage engines that were used in theater and military siege engines, both in the late 16th and early 17th century. This meaning is discovered in late medieval French, and is adopted from French to English in the late 16th century.įrom the beginning of 17th-century, machine could also refer to a scheme or plot or plot, which is now defined by the term machination. A deeper meaning of 'fabric or structure' is found in the classical Latin but not at all in Greek usage. The term mechanical (Greek mekhanikos) is derived from the same Greek roots. The English word machine comes through Middle French from Latin machina, which in turn derives from the Greek (Doric makhana makhana Ionic mekhane mekhane 'contrivance, machine, engine', which is a derivative from mekhos mykhos'means efficient, solution'). Examples include: a huge assortment of vehicles including cars, trains aircrafts, boats and other vehicles appliances in the home and office, such as computers, construction of air handling and water handling systems as well agricultural machinery, machine tools and robots for factory automation and robotics. Modern machines are highly complex structures that comprise mechanical components, structural elements and control parts and come with interfaces for convenient use. Renaissance natural philosophers identified six machines that were the fundamental devices that moved a weight, and calculated the ratio of output force in relation to the input force, which is referred to as mechanical advantage. They also can include sensors and computers that monitor performance and design movement commonly referred to as mechanical systems. Machines can be driven by animals and people in the natural world, using forces like wind and water as well as by chemical, electrical or thermal energy as well as a variety of mechanisms which shape the actuator inputs to ensure a specific application of outward forces and movements. It is a term that is used to refer on artificial devices, which include motors or engines as well as to bio-based macromolecules such as molecular machines.
