Intro to Engineering Final Exam questions with answers

What is an engineer? An engineer is a person who is trained in and uses technological and scientific knowledge to solve practical problems. What is the most effective way to generate potential solutions? Brainstorm How many potential solutions should be generated? As many as possible Why keep an Engineering Notebook? To organize thoughts and prove origin of an idea in legal situations. Why would the ability to create realistic sketches make a person a more competent designer? It allows them to communicate the design more clearly. What is the purpose of sketching your ideas? Sketching allows a person to quickly and clearly communicate an idea. Define and differentiate invention and innovation. Invention: A new product, system or process never created before Innovation: An improvement on an existing product, system or process Define Brainstorm A group technique to generate concepts, solve problems and stimulate creative thinking Define Constraint A limit to a design process Design A plan or drawing to show the look or workings of something before it is built Design Brief A document stating what the problem entails by describing it, how to solve it (briefly) and the constraints Design Statement Describes how to solve the problem Engineering Notebook A place for engineers to plan/design/ document their work Prototype A full-scale working model used to test a design model Research The act of searching for facts or content already in our world The representation of light and shade on a sketch or drawing is? Tonal Shading What type of drawing is used to illustrate product and give presentations? Pictorial What type of drawing is used when the product is intended to be manufactured? Multiview How can statistical and analyzed data be used to inform, justify, and validate a design or process? Statistical and analyzed data can be used to maintain and control data. Why engineers generally adhere to a set of dimensioning standards and guidelines? The part may not fit or function properly if not dimensioned correctly. These delays from not following the standards can cause production delay and/or greater production costs. Why do designers need to fully dimension a part? To fully communicate how the part should be made. What does it mean to over dimension a sketch? When their is duplicate dimensions for a length. A graph of vertical bars representing the frequency distribution of a set of data is called. Histogram A measure of center in a set of numerical data Median A function that represents the distribution of variables as a symmetrical bell-shaped graph. Normal Distribution The value the occurs most frequently in a given data set. Mode The distance of a value in a population from the mean value of the population. Deviation
