PLTW IED 2026 ENGINEERING PRINCIPLES
COMPREHENSIVE PROJECT EXAMINATION
FULL SOLUTIONS
◉ What is the most effective way to generate potential solutions to a
problem? How many alternate solutions should you generate?
Answer: Brainstorming with a group, research and testing possible
solutions
◉ What is an engineer? What types of work do engineers do?
Answer: 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
◉ Why Keep an Engineering Notebook?
Answer: An engineering notebook is recognized 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
practice")
◉ What are the 4 best Practices for the Engineering Notebook?
Answer: Be Neat,
be Accurate,
be Legible,
be Thorough
◉ Explain the concept of proportion.
Answer: 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 create realistic sketches make a person a
more competent designer
Answer: 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.
◉ What is the purpose of sketching your ideas?
,Answer: Sketches provide a means through which one can quickly
and clearly communicate ideas
◉ Define and differentiate invention and innovation.
Answer: Invention: A new product, system, or process that has never
existed before, created by study and experimentation.
Innovation: An improvement of an existing technological product,
system, or method of doing something.
◉ Brainstorm
Answer: A group technique for solving problems, generating ideas,
stimulating creative thinking, etc. by unrestrained spontaneous
participation in discussion
◉ Constrait
Answer: 1. A limit to a design process. Constraints may be such
things as appearance, funding, space, materials, and human
capabilities. 2. A limitation or restriction.
◉ Design
Answer: . An iterative decision-making process that produces plans
by which resources are converted into products or systems that
meet human needs and wants or solve problems. 2. A plan or
drawing produced to show the look and function or workings of
something before it is built or made. 3. A decorative pattern.
, ◉ A Design Brief
Answer: A written plan that identifies a problem to be solved, its
criteria, and its constraints. The design brief is used to encourage
thinking of all aspects of a problem before attempting a solution.
◉ Design Statement
Answer: A part of a design brief that challenges the designer,
describes what a design solution should do without describing how
to solve the problem, and identifies the degree to which the solution
must be executed.
◉ Engineering Notebook
Answer: An engineering notebook is a book in which an engineer
will formally document, in chronological order, all of his/her work
that is associated with a specific design project.
◉ Prototype
Answer: A full-scale working model used to test a design concept by
making actual observations and necessary adjustments.
◉ Research
Answer: The systematic study of materials and sources in order to
establish facts and reach new conclusions.
