PLTW IED Final Exam Study Guide 168 Questions with Correct Answers How might we create the best possible solution to a problem? - Correct Answer Engineers try to 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? - Correct Answer Brainstorming with a group, research and testing possible solutions What is an engineer? What types of work do engineers do? - Correct 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? - Correct 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? - Correct Answer Be Neat, be Accurate, be Legible, be Thorough Explain the concept of proportion. - Correct 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 - Correct 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. 1 / 3
What is the purpose of sketching your ideas? - Correct Answer Sketches provide a means through which one can quickly and clearly communicate ideas Define and differentiate invention and innovation. - Correct 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 - Correct Answer A group technique for solving problems, generating ideas, stimulating creative thinking, etc. by unrestrained spontaneous participation in discussion Constrait - Correct 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 - Correct 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 - Correct 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 - Correct 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 - Correct 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 - Correct Answer A full-scale working model used to test a design concept by making actual observations and necessary adjustments.Research - Correct Answer The systematic study of materials and sources in order to establish facts and reach new conclusions. 2 / 3
Order of Design Process - Correct Answer Define Problem Generate Concepts Develop a Solution Construct and test Prototype Evaluate Solution Present Solution Read through the Engineering Disciplines Power Point and write Each Engineering Field mentioned and one sentence describing what that Engineering Field does. - Correct Answer Chemical Engineering, Civil and Construction Engineering, Electrical and Electronics Engineering, Mechanical Engineering, Aeronautical Engineering, Agricultural Engineering, Architectural Engineering, Automotive Engineering, Biomedical Engineering, Computer Engineering, Industrial Engineering, Manufacturing Engineering Center Line - Correct Answer A line which defines the center of arcs, circles, or symmetrical parts Extension Line - Correct Answer Line which represents where a dimension starts and stops.Dimension Line - Correct Answer A line which represents distance Object Line - Correct Answer A heavy solid line used on a drawing to represent the outline of an object.Construction Line - Correct Answer Line lightly drawn lines to guide drawing other lines and shapes.Hidden Line - Correct Answer A line type that represents an edge that is not directly visible Orthographic Projection - Correct Answer A method of representing three-dimensional objects on a plane having only length and breadth. Also referred to as Right Angle Projection Multi-View Drawing - Correct Answer A drawing which contains views of an object projected onto two or more orthographic planes.
