PLTW Introduction to Engineering
Design (IED) Final Exam Study Guide
2026–2027 – Complete Questions and
Correct Detailed Answers for Engineering
Design and CAD Concepts
How might we create the best possible solution to a problem? -CORRECTANSWER
Engineers try the think "outside the box" in order to solve new problems or find ways to
improve current solutions
What is the most effective way to generate potential solutions to a problem? How many
alternate solutions should you generate? -CORRECTANSWER Brainstorming with a
troup, research and testing possible solutions
What is an engineer? What types of work do engineers do? -CORRECTANSWER
Engineering is the application of mathematics and scientific principles to better or
improve life. An engineer is a person who is trained in and uses technological and
scientific knowledge to solve practical problems. Research, Develop, Design,
Supervise, Manage, Production and Construction, Operations, Plant Management, and
Sales
What are the 4 best practises for the engineering notebook? -CORRECTANSWER - Be
neat
, - Be accurate
- Be logical
- Be thorough
Why keep an engineering notebook? -CORRECTANSWER An engineering notebook is
recognised as a legal document that is used in patent activities to...
- Prove the origin of an idea that led to a solution
- Prove when events or ideas occurred
- Prove diligence in turning the idea into a solution
- Prove when an idea became a working solution ("reduced to practise")
explain the concept of proportion. -CORRECTANSWER Paying close attention to the
underlying basic shapes and the relative proportions of various features of the object
will allow you to more accurately reflect the true shapes and proportions of the object in
your sketch
Why would the ability to make realistic sketches make a person a more competent
designer? -CORRECTANSWER Representing existing objects and new ideas with
sketches can make the design process more effective and efficient and greatly enhance
the ability of others to understand your ideas. Allows them to communicate their ideas
more clearly.
