What is Engineering?



What is Engineering?

• “Engineering is the application of science to thecommon purpose of life.” – Count Rumford

• Standard Definition of engineering today“Engineering is the profession in which a knowledge of the

mathematical and natural sciences, gained by study,experience, and practice, is applied with judgment todevelop ways to utilize, economically, the materials and

forces of nature for the benefit of mankind.”

– Accreditation Board for Engineering and Technology(ABET)



Technology Team

Technology has become so advanced that oneperson cannot be aware of all the intricaciesof one device or process

– Technological problems studied and solved by atechnology team:

• Scientist

•

Engineer • Technologist/technician

• Craftsperson



Scientist

• Primary objective: – Increase the knowledge of nature

• Engage in systematic research – Scientific method:

1. Hypothesis to explain natural phenomenon

2. Conceive and execute experiment to test hypothesis

3. Analyze results and state conclusions4. Generalize hypothesis into law or theory if supported by

results

5. Publish new knowledge



Engineer

• Uses analysis and design

• Applies knowledge of math and natural sciences

• Solve problems

•Develop: – Devices

– Processes

– Structures

– Systems

• Uses a design process



Scientist vs. Engineer

• Scientist

– understand more about natural phenomena

– Acquire more knowledge

• Engineer

– Applies knowledge to design and develop usabledevices, structures, and processes

– Aims to solve a problem



Technologist/Technician

• Technologist (bachelor’s degree) – Direct application of education and experience to make

design modifications

• Technician (associate’s degree) – Perform computations and experiments and prepare

design drawings as requested by engineers andscientists

• Common tasks: – Drafting, estimating, model building, data recording and

reduction, troubleshooting, servicing, and specification



Craftsperson

• Produce parts specified by engineers,scientists, technologists, and technicians – Includes:

• Welder • Machinist

• Electrician

• Carpenter

• Plumber• Mason

– Trade School



Engineering Disciplines

• Areas of study within engineering

• Homework #1: – Pick 8 engineering disciplines from the next slide

– For each of your 8 disciplines, find:• Overview of selected discipline• Areas of specialty within discipline• Essential courses or subject areas• Possible applications of discipline

– Typical engineering functions held by someone who studiesthis discipline
