Mechanical Engineering

The branch of engineering concerned with the design, manufacture, installation, and operation of engines, machines, and manufacturing processes. It involves the application of dynamics, control, thermodynamics and heat transfer, fluid mechanics, strength of materials, material science, tribology, mathematics, and computation.

Please submit company web sites under Business:Industries:Engineering and Business:Industries:Manufacturing as appropriate. Note that categories with an ''@'' at the end of their names are actually cross references to other categories in the Open Directory, and are not formally part of the ''Mechanical Engineering'' category.

This category is intended for information about the field of mechanical engineering such as technical data sources, academic departments and professional societies.

Academic Departments

This category contains web sites for mechanical engineering departments and/or laboratories at colleges and universities. Generally these sites list the faculty, research areas, facilities, and courses offered.

Design

Mechanical Engineering: Design This category is for mechanical design websites that contain significant data useful to mechanical designers and engineers. Please submit commercial engineering product/consulting companies to the "Business" category.

Please submit sites for engineering companies to the "Business" category. This category is for design _data_ useful to mechanical engineers.

HVAC

This category contains sites that discuss the technical aspects of HVAC (heating, ventilation and air conditioning systems) as they are applied to residential and commercial climate control.

Sites that contain theory, information tables or other technical aspects of HVAC systems or components may be included here.

If your site contains technical information about heating, ventilating and air conditioning, submit here.

If your site is only about sales, parts, or installing HVAC systems or units, submit your site to Business: Construction and Maintenance: Commercial Contractors: Mechanical: Heating and Air Conditioning. This category is not a business category.

Mechanical Engineers

Personal pages of scientists and groups working in the field of Mechanical Engineering.

There are separate categories for many of the different branches of engineering. Please submit your site to the most appropriate category.
Please submit only websites that have English language content to this category. If your site is in a language other than English, please submit it to the appropriate category of World.

MEMS

MEMS is an acronym for Micro-Electro-Mechanical Systems, or Microelectromechanical Systems. MEMS are tiny, microscopic electrical and mechanical devices built using the same types of production technologies used to build silicon micro-chips for electronics and computers, and MEMS often are implemented on, or as, micro-chips. This is a new technology with a vast range of potential uses, truly a technological revolution in the making. Some experts teach that MEMS are but a precursor to an even more revolutionary technology: nanotechnology.

Propulsion

This category is for sites that describe propulsion from an engineering standpoint generally, or which relate to more than one operating environment (land, sea, air, space). Specific types of propulsion are placed in subcategories according to operating environment.

Tribology

Tribology is the study of friction, wear and lubrication of interacting surfaces in relative motion. Tribological contacts can be found in all mechanisms, whether mechanical or biological. Friction gives rise to energy loss and wear gives rise to failure.

Please submit sites dealing with tribological research, the development and application of new materials to tribological problems, the development of test methods and the provision of apparatus for evaluating tribological contacts. Consultants engaged in the analysis of tribological contacts are also welcome, as are laboratories offering contract testing services.

Site submissions will be judged on scientific content, with preference given to organizations as opposed to individuals. Please note that personal web sites are unlikely to be accepted, in particular if they contain large amounts of personal data, pictures etc, that are of no scientific relevance.

Please do not submit sites offering commercial lubricants. These should more appropriately be listed under either Business: Industries: Manufacturing: Materials: Lubricants or Shopping: Vehicles: Parts and Accessories: Lubricants.
