What is an Engineer ?

4

What is an Engineer ?

• Engineers are creative designers who apply principles of physics and science to develop products or processes to improve everyday life– The work of engineers affects every part of our lives – at home,

at school, and at work– We have engineers to thank when we use the escalators at the

shopping mall, watch TV on the latest flat-panel display, take videos on the latest iPhone, or get scanned for diseases with the latest imaging equipment at the hospital

• There are many different fields of engineering and areas for specialization

5

Types of Engineers

(Requirement 3)

6

Types of Engineers: Five Core Disciplines

• Civil Engineering– Design roads, railways,

bridges, dams, water supply systems, and sewage systems

– Apply geology and physics

• Chemical Engineering– Apply chemistry to industrial

processes – often to make something new and more environmentally sound

– Develop household products

7

• Electrical Engineering– Design power distribution

systems, electrical machinery, communications, computer systems, control systems, electronic devices

– Apply physics of electricity and magnetism

• Mechanical Engineering– Design wide array of

mechanical devices– Apply physics of motion,

load bearing, forces

8

Automotive Design

Advanced Electronics

Types of Engineers: Five Core Disciplines, con’t

• Mining and Metallurgical Engineering– Work to make mining and

refining metals more predictable, safer, and less expensive

– Create new alloys to meet specific needs (hard, soft, weather-resistant, etc.)

– Apply principles of materials science – study of the properties and behavior of solids, liquids, and gases

9

Steel Manufacturing Plant

Mining Machinery

Types of Engineers: Specialized Disciplines

• Aerospace Engineering– Design airplanes and space

vehicles, including high-powered engines and aerodynamic design principles

– Apply physics of motion, load bearing, forces

• Agricultural Engineering– Design farm and food-

processing equipment and develop systems for irrigation, drainage, and waste disposal

– Develop new ways to grow crops more efficiently

10

AgriculturalMachinery

Advanced Aircraft

Types of Engineers: Specialized Disciplines, con’t

• Architectural Engineering– Work with architects on

designing buildings and the systems that make them functional (elevators, HVAC)

– Can also help design building to resist natural forces

• Bioengineering / Biomedical Engineering– Combines principles of

biology with engineering– Develop medical devices and

prosthetics

11

Gel-based MedicalDrug Delivery

hardware and software such as memory systems, CPUs, graphics cards, and advanced computer architectures

12

Space ShuttleRe-entry Tiles

Advanced Computers

Types of Engineers: Specialized Disciplines, con’t

• Environmental Engineering– Work to reduce man’s effects

on the environment by improving quality of the air, water and land

– Develop systems to reduce pollution and repair damage

• Industrial Engineering– Design manufacturing plants

and processes for maximum efficiency and lower costs of production

13

Water Treatment Plant

Industrial Plant

Types of Engineers: Specialized Disciplines, con’t

• Manufacturing Engineering– Develop high-speed

automated machinery and robotics to yield high quality products from a manufacturing plant

• Marine/Naval Engineering– Design ships and ocean-

based structures to work in harsh ocean environments and resist weather, salt, water currents, waves, and animals

14

Manufacturing Plant

Ship Design

Types of Engineers: Specialized Disciplines, con’t

• Material Engineering– Work with all kinds of raw

materials, both natural and synthetic, to create new materials that meet specific needs for strength, flexibility, durability, etc.

• Nuclear Engineering– Design systems that operate

with radiation, including power plants, medical instruments, and weapons

– Must design shielding and protection systems

15

Material Flammability

Nuclear Power Plant

Types of Engineers: Specialized Disciplines, con’t

• Ocean Engineering– Develop ways to harvest food

from the ocean or harness energy from waves

– Develop new methods and machines to allow humans to work and live beneath oceans

• Petroleum Engineering– Specialized chemical

engineers who develop efficient processes and machinery to extract crude petroleum from the earth

16

Ocean PipelineDesign

Off-Shore Oil Rig

Types of Engineers: Specialized Disciplines, con’t

• Software Engineering– Apply principles of

computer science to design complex software systems including control/monitoring systems and of course video games

• Systems Engineering– Look at processes from a

“big picture” systems viewpoint to design large, complex engineering systems to meet customer requirements

17

Tactical Heads-Up Display

Engineering Approach to

Problem Solving (Requirement 5)

18

Engineering Approach to Problem Solving

1. Make a plan showing approach, resources, required tools, and schedule

2. Describe the project requirements3. Plan the project’s activities and task schedules4. Conduct research – get ideas5. Develop the best ideas for alternative solutions6. Analyze the best ideas and compare them7. Select the best idea8. Perform the construction or solution of the project9. Check the solution

19

Patrol “Bridge” Building

Competition

20

Patrol Princess Pony Diving Board Building Competition

• Parts provided (think why I would give these)– Three 8 foot bridge sections plus 2 yardsticks– 2 small clamps, 2 large clamps, 20 feet blue tape– 200 feet of string plus various Legos, scissors, 1 Princess Pony

21

Patrol Princess Pony Diving Board Building Competition

• Rules– Attachment to all parts of table OK, can’t modify/damage table– Nothing can touch floor (except…)– No modification of parts (can’t drill holes, break, etc.)

• Exception: can cut string and tape as desired

• Bonus advantage for trivia question winner– Patrol may have one brace to floor in 1st or 2nd bridge section

• Diving Boards judged on two measurable criteria– Length – #1 = 10 points, #2 = 8 points, #3 = 6 points– Load Bearing - #1 = 10 points, #2 = 8 points, #3 = 6 points
