ENGINEERING - MECHANICAL |
|
Mechanical engineering is a very broad field of engineering that involves the application of physical principles for analysis, design, manufacturing, and maintenance of mechanical systems. The system can be as simple as the design of a chair for comfort or as complex as the operations of a turbocharged engine for speed. It can be as small as the manufacturing of a nano-sized gear or as large as the structure of a supertanker used to carry oil around the world.

EXPERT WITNESS SALES |
|
An expert witness is a witness, who by virtue of education, or profession, or experience, is believed to have special knowledge of his subject beyond that of the average person, sufficient that others may officially (and legally) rely upon his opinion.

METALLURGY |
|
Metallurgy is a domain of materials science and of materials engineering that studies the physical and chemical behavior of metallic elements, their intermetallic compounds and their mixtures, which are called alloys.
Extractive metallurgy is the practice of separating metals from their ore, and refining them into a pure metal. In order to convert a metal oxide or sulfide to a metal, the metal oxide must be reduced either chemically or electrolytically.

PROFESSIONAL ENGINEER |
|
Professional Engineer is the term for registered or licensed engineers in some countries, including the United States and Canada. Some individuals in these countries who have a degree in engineering from an accredited four-year university but do not have a license use the title Degreed Engineer.
The earmark that distinguishes a professional engineer is the authority to sign and seal or stamp engineering documents (drawings and calculations) for a design or a structure, thus taking legal responsibility for it.
