What is Engineering?

The Accreditation Board for Engineering and Technology (ABET) defines engineering: “the profession in which a knowledge of the mathematical and natural sciences gained by study, experience, and practice is applied with judgment to develop ways to utilize, economically, the materials and forces of nature for the benefit of mankind.”

What is Engineering?

Engineering is a profession like medicine, law, etc. that aspires to high standards of conduct and recognizes its responsibility to the general public.

What is Technology?

The application of scientific knowledge for practical purposes, especially in industry.

Technology refers to the collection of tools, including machinery, modifications, arrangements and procedures used by humans. Engineering is the discipline that seeks to study and design new technologies.

Technology is Outcome of Engineering

Technology Team

Scientist - Like an engineer, but a primary goal is the expansion of knowledge and understanding physical processes.

Engineer - Applies knowledge of math and the physical sciences to the efficient design and construction of usable devices, structures and processes.

Technology Team

Technologist - Technologists focus on direct application of established engineering principles and processes. Math, the physical sciences, and underlying engineering theory receive limited coverage. More interested in hardware and processes.

Technology Team

Technician - Completes a 2 year degree in a narrow technical area such as electronics, drafting, or machining.

Artisans - Training may be a combination of schooling and work experience. Examples include, welders, machinists, electricians, carpenters, painters, steel workers, and artists.

Engineering Functions

The focus of an engineer’s work typically falls into one or more of the following areas:

Research - explore, discover and apply new principles

Development - transform ideas or concepts into production processes

Design - link the generation of ideas and the production

Engineering Functions

Production and testing - manufacture and assemble components or products

Sales - market engineering products Operations - maintain equipment and facilities Construction - prior to construction organizes

bids, during construction supervises certain components of process

Engineering Functions

Management - optimize the use of resources (equipment, labor, finances)

Education - teach engineering principles in university and industrial settings

Consulting - provide specialized engineering services the clients. May work alone or in partnership other engineers.

What Do Mechanical Engineers Do?

• Design, develop and produce many of tools used by other engineer (innovations)

• Study the behavior of the materials when forces are applied to them or when they are heated or cooled. Using this knowledge, they design machines such as automobiles, air conditioners and submarines.

• Involve with all forms of energy utilization and conversion, manufacturing (production) material and processes and engines.

• Use mathematics and physical sciences to analyze problem

• Expected to constantly improve, re-design and invent equipment

• May work in maintenance, technical sales, or as administrators or managers. 31
