In systems engineering it may involve black-box testing performed on a system ( for example: a piece of software, lots of manufactured mechanical parts, or batches of chemical products ) prior to its delivery.

* Bearing ( mechanical ), a component that separates moving parts and takes a load

* Balancing machine, a machine that balances mechanical rotating parts to lessen vibration.

Surface forces or contact forces, expressed as force per unit area, can act either on the bounding surface of the body, as a result of mechanical contact with other bodies, or on imaginary internal surfaces that bound portions of the body, as a result of the mechanical interaction between the parts of the body to either side of the surface ( Euler-Cauchy's stress principle ).

The 1972 science fiction novel Cyborg, by Martin Caidin, told the story of a man whose damaged body parts are replaced by mechanical devices (" bionics ").

In R2, most of his mechanical parts are internalized.

Zuse's purely mechanical, but already binary Z1, finished in 1938, never worked reliably due to problems with the precision of parts.

The Z1 contained some 30, 000 metal parts and never worked well due to insufficient mechanical precision.

The mechanical advantage of the block and tackle is equal to the number of parts of the rope that support the moving block.

If the rope and pulley system does not dissipate or store energy, then its mechanical advantage is the number of parts of the rope that act on the load.

A single movable pulley is supported by two parts of the same rope and has a mechanical advantage of two.

Technology advances make cyberware ( mechanical replacement body parts ) and bioware ( augmented vat-grown body parts implanted in place of natural organs ) common.

If the lubrication is lost, the moving parts may grind against each other and destroy the fine mechanical tolerances required for the proper acoustic performance of the stethoscope.

A mechanical adhesive bond may be formed around glass fibre mat or tissue to reinforce joints or to fabricate small parts.

** Tolerance analysis, the study of accumulated variation in mechanical parts and assemblies

Another aspect of urban exploration is the practice of exploring active or in use buildings which includes gaining access to secured or " member-only " areas, mechanical rooms, roofs, elevator rooms, abandoned floors and other normally unseen parts of working buildings.

Others, such as DIP switches, are composed of two ( or more ) plastic housing parts snapped, welded, or glued together around a set of contacts and tiny mechanical parts, with the leads emerging through molded-in holes or notches in the plastic.

When designing objects, Engineers must ensure the mechanical resonance frequencies of the component parts do not match driving vibrational frequencies of motors or other oscillating parts, a phenomenon known as resonance disaster.

He was early exposed to the mechanical world, and in his youth often helped his father, David Brown, master clock and watchmaker, as he plied his trade.

Some early scientists such as Georg Ernst Stahl ( 1659-1734 ) and Francisque Bouillier ( 1813 – 1899 ) had supported a form of animism which life and mind, the directive principle in evolution and growth, holding that all cannot be traced back to chemical and mechanical processes, but that there is a directive force which guides energy without altering its amount.

In the early 1860s, Frenchmen Pierre Michaux and Pierre Lallement took bicycle design in a new direction by adding a mechanical crank drive with pedals on an enlarged front wheel ( the velocipede ).

Moreover, early Christian Church Fathers used canon to rank the authoritative texts of the New Testament, preserving them, given the expense of vellum and papyrus and mechanical book reproduction, thus, being comprehended in a canon ensured a book ’ s preservation as the best way to retain information about a civilization.

By the early 1970s electronic pocket calculators ended manufacture of mechanical calculators, although the Curta remains a popular collectable item.

The physical principle of production of mechanical force by the interactions of an electric current and a magnetic field was known as early as 1821.

Armstrong showed an interest in electrical and mechanical devices, particularly trains, from an early age.

Other early versions of mechanical devices used to perform one or another type of calculations include the planisphere and other mechanical computing devices invented by Abū Rayhān al-Bīrūnī ( c. AD 1000 ); the equatorium and universal latitude-independent astrolabe by Abū Ishāq Ibrāhīm al-Zarqālī ( c. AD 1015 ); the astronomical analog computers of other medieval Muslim astronomers and engineers ; and the astronomical clock tower of Su Song ( c. AD 1090 ) during the Song Dynasty.

In the early days of binary vacuum-tube computers, their reliability was poor enough to justify marketing a mechanical octal version (" Binary Octal ") of the Marchant desktop calculator.

Joysticks were present in early planes, though their mechanical origins are uncertain.

The triode was vital in the creation of long-distance telephone and radio communications, radars, and early electronic digital computers ( mechanical and electro-mechanical digital computers already existed using different technology ).

Although used in the early days of the personal computer ( on the Sinclair ZX80, ZX81 and Atari 400 ), they have been supplanted by the more tactile dome and mechanical switch keyboards.

In the early days of diesel railroad propulsion development, electric, hydraulic and mechanical power transmission systems were all employed with varying degrees of success.

From early beginnings with the invention of the phonograph using purely mechanical techniques, the field has advanced with the invention of electrical recording, the mass production of the 78 record, the magnetic wire recorder followed by the tape recorder, the vinyl LP record.

In the early 1890s Lippincott fell victim to the unit's mechanical problems and also to resistance from stenographers.

Descartes discovered an early form of the law of conservation of mechanical momentum ( a measure of the motion of an object ), and envisioned it as pertaining to motion in a straight line, as opposed to perfect circular motion, as Galileo had envisioned it.

In arthritis of non-inflammatory causes, signs of inflammation and early morning stiffness are less prominent with stiffness typically less than 1 hour, and movements induce pain caused by mechanical arthritis.

According to Dusted Magazine, Sakamoto's use of squelching bounce sounds and mechanical beats was later incorporated in early electro and hip hop music productions such as “ Message II ( Survival )” ( 1982 ) by Melle Mel and Duke Bootee, “ Magic ’ s Wand ” ( 1982 ) by Whodini and Thomas Dolby, Twilight 22 ’ s “ Electric Kingdom ” ( 1983 ), and Kurt Mantronik's Mantronix: The Album ( 1985 ).

In its early stages of development, television employed a combination of optical, mechanical and electronic technologies to capture, transmit and display a visual image.

The first images transmitted electrically were sent by early mechanical fax machines, including the pantelegraph, developed in the late nineteenth century.

When well-regulated mechanical clocks became widespread in the early 19th century ,| publisher = Canonical Ltd.

Jensen also criticized Gould for concentrating on long-disproven arguments ( noting that 71 % of the book's references preceded 1950 ), rather than addressing " anything currently regarded as important by scientists in the relevant fields ", suggesting that drawing conclusions from early human intelligence research is like condemning the contemporary automobile industry based upon the mechanical performance of the Ford Model T.

The design of UDC lends itself to machine readability, and the system has been used both with early automatic mechanical sorting devices, and modern library OPACs.
