UNIT 3 – Engineering Design

Engineering, the systematic application of mathematical, scientific, and technical principles, produces tangible end products that meet our needs and desires.

What is a systematic application of something?– an organized or established procedure; – a set of steps

The Core Technologies

PURPOSE OF LESSON

• To familiarize students with the core technologies (engineering resources) – the building blocks of the designed world – by having students identify and describe the core technologies as they are applied in the designed world.

What is technology?The application of knowledge, tools, and skills to solve problems and extend human capabilities.

What is a technology system?A Technology System is a group of subsystems working together to solve problems and extend human capabilities.

U3c-L1

A technology system is a group of resources (subsystems) working together to solve problems

and extend human capabilities.

Core Technologies are the subsystems:

1. Mechanical

2. Structural

3. Electrical

4. Electronic

5. Thermal

6. Fluid

7. Optical

8. Bio-Tech

9. MaterialTechnology System

• There are several engineering resources (core technologies) that are the “building blocks” of all technology systems.

• We could store the core technologies on shelves • We can go to those shelves and use technologies

according to our needs in problem solving.

Unit Divider – The shelves on whichwe keep the Core Technologies

Your final product will look like:Steps:1. Draw LIGHT construction

lines using the dimensions to the right.

2. Offset lines 3/16”1. Vertical lines left2. Horizontal lines down

3. Darken the shelves with HEAVY object lines

4. Draw LIGHT guidelines1. 3/8” for title2. 5/16” for shelves

LAST: Title the divider and the shelves

U3c-L1

1. Identify the problem that the technology system solves.

2. Analyze the technology system:What is its function and/or application?

3. List the resources (core technologies) you recognize in the technology system.
