PLTW IED Final Exam Study Guide 1.How might we create the best possible solution to a problem?ANS Engineers try to think "outside the box" in order to solve new problems or find ways to improve current solutions.
2.What is the most effective way to generate potential solutions to a problem?How many alternate solutions should you generate?ANS Brainstorming with a group, research and testing possible solutions 3.What is an engineer? What types of work do engineers do?ANS 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 knowl- edge to solve practical problems. Research, Develop, Design, Supervise, Manage, Production and Construction,operations,plant management, and sales 4.Why Keep an Engineering Notebook?ANS 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 1 / 4

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") 5.What are the 4 best Practices for the Engineering Notebook?ANS Be Neat, be Accurate, be Legible, be Thorough 6.Explain the concept of proportion.ANS 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 7.Why would the ability to create realistic sketches make a person a more competent designer ANS 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.
8.What is the purpose of sketching your ideas?ANS Sketches provide a means through which one can quickly and clearly communicate ideas 2 / 4

9.Define and differentiate invention and innovation.ANS Invention A new product, system, or process that has never existed before, created by study and experimen- tation.Innovation An improvement of an existing technological product, system, or method of doing something.
10.Brainstorm ANS A group technique for solving problems, generating ideas, stimu- lating creative thinking, etc. by unrestrained spontaneous participation in discussion 3 / 4

11.Constrait ANS 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.
12.Design ANS . 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.
13.A Design Brief ANS 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.
14.Design Statement ANS 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.
15.Engineering Notebook ANS An engineering notebook is a book in which an en- gineer will formally
