A wider meaning of 'fabric, structure' is found in classical Latin, but not in Greek usage. This meaning is found in late medieval French, and is adopted from the French into English in the mid-16th century.
</p><p>In the 17th century, the word machine could also mean a scheme or plot, a meaning now expressed by the derived <a href="https://en.wiktionary.org/wiki/machination" class="extiw" title="wikt:machination">machination</a>. The modern meaning develops out of specialized application of the term to <a href="/wiki/Stagecraft" title="Stagecraft">stage engines</a> used in <a href="/wiki/Elizabethan_theater" class="mw-redirect" title="Elizabethan theater">theater</a> and to military <a href="/wiki/Siege_engine" title="Siege engine">siege engines</a>, both in the late 16th and early 17th centuries. The <a href="/wiki/OED" class="mw-redirect" title="OED">OED</a> traces the formal, modern meaning to <a href="/wiki/John_Harris_(writer)" title="John Harris (writer)">John Harris</a>' <i><a href="/wiki/Lexicon_Technicum" title="Lexicon Technicum">Lexicon Technicum</a></i> (1704), which has:
</p>
<dl><dd><i>Machine, or Engine, in Mechanicks, is whatsoever hath Force sufficient either to raise or stop the Motion of a Body. Simple Machines are commonly reckoned to be Six in Number, viz. the Ballance, Leaver, Pulley, Wheel, Wedge, and Screw. Compound Machines, or Engines, are innumerable.</i></dd></dl>
<p>The word <i><a href="https://en.wiktionary.org/wiki/engine" class="extiw" title="wikt:engine">engine</a></i> used as a (near-) synonym both by Harris and in later language derives ultimately (via <a href="/wiki/Old_French" title="Old French">Old French</a>) from Latin <span title="Latin-language text"><i lang="la">ingenium</i></span> 'ingenuity, an invention'.

<p>The idea that a machine can be decomposed into simple movable elements led <a href="/wiki/Archimedes" title="Archimedes">Archimedes</a> to define the <a href="/wiki/Lever" title="Lever">lever</a>, <a href="/wiki/Pulley" title="Pulley">pulley</a> and <a href="/wiki/Screw" title="Screw">screw</a> as <a href="/wiki/Simple_machines" class="mw-redirect" title="Simple machines">simple machines</a>. By the time of the Renaissance this list increased to include the <a href="/wiki/Wheel_and_axle" title="Wheel and axle">wheel and axle</a>, <a href="/wiki/Wedge_(mechanical_device)" class="mw-redirect" title="Wedge (mechanical device)">wedge</a> and <a href="/wiki/Inclined_plane" title="Inclined plane">inclined plane</a>. The modern approach to characterizing machines focusses on the components that allow movement, known as <a href="/wiki/Joint_(mechanics)" class="mw-redirect" title="Joint (mechanics)">joints</a>.
</p><p>Wedge (hand axe): Perhaps the first example of a device designed to manage power is the <a href="/wiki/Hand_axe" title="Hand axe">hand axe</a>, also called <a href="/wiki/Biface" class="mw-redirect" title="Biface">biface</a> and <a href="/wiki/Olorgesailie" title="Olorgesailie">Olorgesailie</a>. A hand axe is made by chipping stone, generally flint, to form a bifacial edge, or <a href="/wiki/Wedge_(mechanical_device)" class="mw-redirect" title="Wedge (mechanical device)">wedge</a>. A wedge is a simple machine that transforms lateral force and movement of the tool into a transverse splitting force and movement of the workpiece. The available power is limited by the effort of the person using the tool, but because power is the product of force and movement, the wedge amplifies the force by reducing the movement. This amplification, or <a href="/wiki/Mechanical_advantage" title="Mechanical advantage">mechanical advantage</a> is the ratio of the input speed to output speed. For a wedge this is given by 1/tanα, where α is the tip angle. The faces of a wedge are modeled as straight lines to form a sliding or <a href="/wiki/Prismatic_joint" title="Prismatic joint">prismatic joint</a>.
</p><p>Lever: The <a href="/wiki/Lever" title="Lever">lever</a> is another important and simple device for managing power. This is a body that pivots on a fulcrum. Because the velocity of a point farther from the pivot is greater than the velocity of a point near the pivot, forces applied far from the pivot are amplified near the pivot by the associated decrease in speed. If <i>a</i> is the distance from the pivot to the point where the input force is applied and <i>b</i> is the distance to the point where the output force is applied, then <i>a/b</i> is the <a href="/wiki/Mechanical_advantage" title="Mechanical advantage">mechanical advantage</a> of the lever. The fulcrum of a lever is modeled as a hinged or <a href="/wiki/Revolute_joint" title="Revolute joint">revolute joint</a>.
</p><p>Wheel: The <a href="/wiki/Wheel" title="Wheel">wheel</a> is an important early machine, such as the <a href="/wiki/Chariot" title="Chariot">chariot</a>. A wheel uses the law of the lever to reduce the force needed to overcome <a href="/wiki/Friction" title="Friction">friction</a> when pulling a load. To see this notice that the friction associated with pulling a load on the ground is approximately the same as the friction in a simple bearing that supports the load on the axle of a wheel. However, the wheel forms a lever that magnifies the pulling force so that it overcomes the frictional resistance in the bearing.

<p>The classification of <a href="/wiki/Simple_machine" title="Simple machine">simple machines</a> to provide a strategy for the design of new machines was developed by <a href="/wiki/Franz_Reuleaux" title="Franz Reuleaux">Franz Reuleaux</a>, who collected and studied over 800 elementary machines.<sup id="cite&#95;ref-40" class="reference"><a href="#cite_note-40"><span class="cite-bracket">&#91;</span>40<span class="cite-bracket">&#93;</span></a></sup> He recognized that the classical <a href="/wiki/Simple_machine" title="Simple machine">simple machines</a> can be separated into the lever, pulley and wheel and axle that are formed by a body rotating about a hinge, and the inclined plane, wedge and screw that are similarly a block sliding on a flat surface.<sup id="cite&#95;ref-41" class="reference"><a href="#cite_note-41"><span class="cite-bracket">&#91;</span>41<span class="cite-bracket">&#93;</span></a></sup>
</p><p>Simple machines are elementary examples of <a href="/wiki/Kinematic_chain" title="Kinematic chain">kinematic chains</a> or <a href="/wiki/Linkage_(mechanical)" title="Linkage (mechanical)">linkages</a> that are used to model <a href="/wiki/Mechanical_systems" class="mw-redirect" title="Mechanical systems">mechanical systems</a> ranging from the steam engine to robot manipulators. The bearings that form the fulcrum of a lever and that allow the wheel and axle and pulleys to rotate are examples of a <a href="/wiki/Kinematic_pair" title="Kinematic pair">kinematic pair</a> called a hinged joint. Similarly, the flat surface of an inclined plane and wedge are examples of the <a href="/wiki/Kinematic_pair" title="Kinematic pair">kinematic pair</a> called a sliding joint. The screw is usually identified as its own kinematic pair called a helical joint.
</p><p>This realization shows that it is the joints, or the connections that provide movement, that are the primary elements of a machine. Starting with four types of joints, the rotary joint, sliding joint, cam joint and gear joint, and related connections such as cables and belts, it is possible to understand a machine as an assembly of solid parts that connect these joints called a <a href="/wiki/Mechanism_(engineering)" title="Mechanism (engineering)">mechanism</a>.<sup id="cite&#95;ref-Uicker2003&#95;42-0" class="reference"><a href="#cite_note-Uicker2003-42"><span class="cite-bracket">&#91;</span>42<span class="cite-bracket">&#93;</span></a></sup>

<p>A <b>mechanical system</b> manages <a href="/wiki/Power_(physics)" title="Power (physics)">power</a> to accomplish a task that involves forces and movement. Modern machines are systems consisting of (i) a power source and <a href="/wiki/Actuator" title="Actuator">actuators</a> that generate forces and movement, (ii) a <a href="/wiki/Machine_(mechanical)" class="mw-redirect" title="Machine (mechanical)">system of mechanisms</a> that shape the actuator input to achieve a specific application of output forces and movement, (iii) a controller with sensors that compare the output to a performance goal and then directs the actuator input, and (iv) an interface to an operator consisting of levers, switches, and displays. This can be seen in Watt's steam engine in which the power is provided by steam expanding to drive the piston. The walking beam, coupler and crank transform the linear movement of the piston into rotation of the output pulley. Finally, the pulley rotation drives the flyball governor which controls the valve for the steam input to the piston cylinder.

<p>Mechanization (or mechanisation in <a href="/wiki/British_English" title="British English">BE</a>) is providing human operators with machinery that assists them with the muscular requirements of work or displaces muscular work. In some fields, mechanization includes the use of hand tools. In modern usage, such as in engineering or economics, mechanization implies machinery more complex than hand tools and would not include simple devices such as an un-geared horse or donkey mill. Devices that cause speed changes or changes to or from reciprocating to rotary motion, using means such as <a href="/wiki/Gear" title="Gear">gears</a>, <a href="/wiki/Pulley" title="Pulley">pulleys</a> or <a href="/wiki/Line_shaft" title="Line shaft">sheaves</a> and belts, <a href="/wiki/Drive_shaft" title="Drive shaft">shafts</a>, <a href="/wiki/Cam_(mechanism)" title="Cam (mechanism)">cams</a> and <a href="/wiki/Crank_(mechanism)" title="Crank (mechanism)">cranks</a>, usually are considered machines. After electrification, when most small machinery was no longer hand powered, mechanization was synonymous with motorized machines.<sup id="cite&#95;ref-59" class="reference"><a href="#cite_note-59"><span class="cite-bracket">&#91;</span>59<span class="cite-bracket">&#93;</span></a></sup>

<p>The <a href="/wiki/Rigid-body_dynamics" class="mw-redirect" title="Rigid-body dynamics">dynamic analysis</a> of machines begins with a rigid-body model to determine reactions at the bearings, at which point the elasticity effects are included. The <a href="/wiki/Rigid-body_dynamics" class="mw-redirect" title="Rigid-body dynamics">rigid-body dynamics</a> studies the movement of systems of interconnected bodies under the action of external forces. The assumption that the bodies are rigid, which means that they do not deform under the action of applied forces, simplifies the analysis by reducing the parameters that describe the configuration of the system to the translation and rotation of reference frames attached to each body.<sup id="cite&#95;ref-62" class="reference"><a href="#cite_note-62"><span class="cite-bracket">&#91;</span>62<span class="cite-bracket">&#93;</span></a></sup><sup id="cite&#95;ref-63" class="reference"><a href="#cite_note-63"><span class="cite-bracket">&#91;</span>63<span class="cite-bracket">&#93;</span></a></sup>

<p>The dynamic analysis of a machine requires the determination of the movement, or <a href="/wiki/Kinematics" title="Kinematics">kinematics</a>, of its component parts, known as kinematic analysis. The assumption that the system is an assembly of rigid components allows rotational and translational movement to be modeled mathematically as <a href="/wiki/Rigid_transformation" title="Rigid transformation">Euclidean, or rigid, transformations</a>. This allows the position, velocity and acceleration of all points in a component to be determined from these properties for a reference point, and the angular position, <a href="/wiki/Angular_velocity" title="Angular velocity">angular velocity</a> and <a href="/wiki/Angular_acceleration" title="Angular acceleration">angular acceleration</a> of the component.
