3. What is Engineering?
Engineering is the application of science and mathematics to improve society
Engineers exist to design, construct, operate, or maintain the systems and devices that drive our society, making them as effective and efficient as possible
The bottom line: engineering is problem solving
Engineering is the art or science of making practical.
~ Samuel C. Florman

7. Civil Engineering
Civil engineers meet society’s need for infrastructure and water systems.
Civil Engineering is the most diverse discipline because of the wide range of subcategories:

8. Civil Engineering A civil engineer might be asked to: Design a bridge
Build a dam
Determine the safest speed of a road
Analyze data on the soil for a foundation
Interpret numbers to forecast future traffic problems
Civil Engineering

9. Environmental Engineering
Environmental engineering is the protection and restoration of the environment.
Environmental engineers have an expertise in water/air quality, water and wastewater treatment.
LOTS of chemistry

10. Environmental Engineering
An environmental engineer might be asked to:
Design a wastewater treatment facility
Determine how to dispose of toxic chemicals
Use computer models to figure out how much pollution a city will create

11. Mechanical Engineering
Mechanical engineering applies the principles of engineering, physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems.
It involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools.

12. Mechanical Engineering
A mechanical engineer might be asked to:
Design automobiles, refrigeration & heating systems, and industrial equipment
Determine the efficiency of an engine
Use computer models to figure out the optimum design and layout of a manufacturing plant

13. Electrical Engineering
Electrical engineering generally deals with the study and application of electricity, electronics, and electromagnetism.
Today it covers a wide range of subfields including electronics, digital computers, power engineering, telecommunications, control systems, RF engineering, and signal processing.

14. Electrical Engineering
An electrical engineer might be asked to:
Design a PC, cell phone, radar equipment, or wireless communication system
Design and build an efficient power generation and distribution system
Use computer models to figure out the propagation of radio frequency signals through different mediums

15. Chemical Engineering
Chemical engineering applies the natural sciences (e.g., chemistry and physics) and life sciences (e.g. biology, microbiology and biochemistry) to production, transformation, transportation and proper usage of chemicals, materials and energy.
It essentially deals with the engineering of chemicals, energy and the processes that create and/or convert them.

16. Chemical Engineering A chemical engineer might be asked to:
Develop new or adapted substances for products ranging from foods and beverages to cosmetics to cleaners to pharmaceutical ingredients
Develop new technologies such as fuel cells, hydrogen power, nanotechnology, polymers, and biomedical products.

17. Software Engineering
Software engineering is the study and application of engineering to the design, development, and maintenance of software.
An engineering discipline that is concerned with all aspects of software production.
It is the establishment and use of sound engineering principles in order to economically obtain software that is reliable and works efficiently on real machines.

18. Software Engineering A software engineer might be asked to:
Design a computer operating system, cell phone apps, industrial control software, or other embedded application software
Assemble extensive amounts of code into working applications, as well as to update and fix problems in existing software
Create flowcharts and diagrams that demonstrate how applications function

19. What is an engineer’s biggest priority???
SAFETY!!!
Do example

20. The Systems Engineering Process

21. The Problem Solving Cycle
State the Problem
Redefine the Problem
Identify Constraints
Add Specifications
Look at Potential Causes
Identify Possible Solutions
Analyze the Alternatives
Select the Most practical Alternative
Draw example on Board

23. Let’s Do an Example
An environmentally concerned client wants to change her home heating system from electricity to gas in order to dramatically reduce her heating costs.

24. Redefine
What is the most cost-effective change the woman can make to reduce her energy costs?

25. Identify Constraints home is heated by an electric system
house has single pane windows and little insulation in the attic
energy costs are significantly higher than those of others in her area with comparable homes
environmentally concerned

26. Add Specifications Your solution must be…
Feasible
Safe
Legal
Practical
Etc.
Time consuming – create chart

27. Identify Possible Solutions
Look at Potential Causes
What would create a high electricity bill?
Identify Possible Solutions
Brainstorm possible solutions
Analyze the Alternatives
we must weigh the advantages and disadvantages of each alternative.
Construct a matrix and time chart
