RWTH Aachen University, established as Polytechnicum in 1870, is one of the Germany's Universities of Excellence with strong emphasis on technological research, especially for electrical and mechanical engineering, computer sciences, physics, and chemistry.

It was " intended to afford a medium for the presentation and analysis of any and all questions of interest or importance in pure and applied Mathematics, embracing especially all new and interesting discoveries in theoretical and practical astronomy, mechanical philosophy, and engineering ".

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.

A prosthetic eye, an example of a biomedical engineering application of mechanical engineering and biocompatible material s to ophthalmology.

While many engineering fields ( such as mechanical or electrical engineering ) do not need graduate-level training to obtain an entry-level job in their field, the majority of BME positions do prefer or even require them.

In the UK, mechanical engineers working in the areas of Medical Engineering, Bioengineering or Biomedical engineering can gain Chartered Engineer status through the Institution of Mechanical Engineers.

" Chemical engineering ", describing the use of mechanical equipment in the chemical industry, became common vocabulary in England after 1850.

* Crank ( mechanism ), in mechanical engineering, a bent portion of an axle, or shaft, or an arm keyed at right angles to the end of a shaft, by which motion is imparted to or received from it

Before it emerged as a unique discipline, control engineering was practiced as a part of mechanical engineering and control theory was studied as a part of electrical engineering, since electrical circuits can often be easily described using control theory techniques.

Control engineering is the engineering discipline that focuses on the modeling of a diverse range of dynamic systems ( e. g. mechanical systems ) and the design of controllers that will cause these systems to behave in the desired manner.

As a result, focus is shifting back to the mechanical engineering discipline, as intimate knowledge of the physical system being controlled is often desired.

Lawson worked with Nick Talesfore who was responsible for the Industrial Design of the hand controllers, console and video game cartridges as the manager of Industrial Design ; and, Ron Smith who was responsible for the mechanical engineering of the video cartridges and the eight degrees of freedom hand controllers.

Also includes an e-book library of classic texts on mechanical design and engineering.

He is a brilliant, ruthless scientist who has demonstrated mastery of robotics, mechatronics, metallurgy, chemistry, artificial intelligence, cloning, genetic engineering, biology, physics, astronomy, earth science, military tactics, cybernetics and mechanical engineering.

Mechatronics is an engineering discipline which deals with the convergence of electrical and mechanical systems.

Also includes an e-book library of classic texts on mechanical design and engineering.

However the general concept of linear filtering is broader, also used in statistics, data analysis, and mechanical engineering among other fields and technologies.

* List of mechanical engineering topics

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.

Lastly, mechanical properties of these biopolymers can often be measured using optical tweezers or atomic force microscopy.

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 ).

To illustrate the difference: The sound and the change in the air's drift velocity ( the force of the wind gust ) cross distance at rates equaling the speeds of sound and of mechanical transmission of force ( not higher than rate of drift velocity ); while a change in an EM field and the change in current ( electrons ' drift velocity ) both propagate across distance at rates much higher than the actual drift velocity.

1st century BC ), described the invention of a mechanical arrow firing catapult ( katapeltikon ) by a Greek task force in 399 BC.

In measurements of purely mechanical systems ( involving units of length, mass, force, energy, pressure, and so on ), the differences between CGS and SI are straightforward and rather trivial ; the unit-conversion factors are all powers of 10 arising from the relations and.

The operations of numerous common rotating mechanical systems are most easily conceptualized in terms of centrifugal force.

The two strands of DNA in a double helix can therefore be pulled apart like a zipper, either by a mechanical force or high temperature.

Originally an engine was a mechanical device that converted force into motion.

In an internal combustion engine the expansion of the high temperature and high pressure gases, which are produced by the combustion, directly applies force to components of the engine, such as the pistons or turbine blades or a nozzle, and by moving it over a distance, generates useful mechanical energy.

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.

A hammer is basically a force amplifier that works by converting mechanical work into kinetic energy and back.

This force moves the component over a distance, transforming chemical energy into useful mechanical energy.

In some ion channels, passage through the pore is governed by a " gate ," which may be opened or closed by chemical or electrical signals, temperature, or mechanical force, depending on the variety of channel.

Thus the engine expended much of its energy in repeatedly heating the cylinder rather than in delivering mechanical force.

However, quantum mechanical effects force electrons to take on discrete positions in orbitals.

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system.

If a and b are distances from the fulcrum to points A and B and if force F < sub > A </ sub > applied to A is the input force and F < sub > B </ sub > exerted at B is the output, the ratio of the velocities of points A and B is given by a / b, so the ratio of the output force to the input force, or mechanical advantage, is given by

By adding a pulley to the fixed block of a gun tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a.

Alternatively a design based on an orthogonal triad of fibre optic or ring laser gyroscopes will eliminate these errors, as they depend upon no mechanical parts, instead using the principles of optical path difference to determine rate of rotation.

An optical computer mouse or " optic mouse " uses a light-emitting diode and photodiodes to detect movement relative to a surface, unlike a mechanical mouse which has a ball which rotates orthogonal shafts which drive chopper wheels for distance measurement.
