- 1How might we create the best possible solution to a problem?Think "outside of the box" to solve new problems or find ways to improve current solutions
- 2Why keep an Engineering Notebook?An engineering notebook:
Proves the origin of an idea that led to a solution
Prove when events or idea occurred
Prove diligence in turning the idea into a solution
Prove when an idea became a solution - 3What are the 4 best practices for the Engineering Notebook?Be neat
Be accurate
Be Legible
Be Thorough - 4Define and differentiate invention and innovationAn invention is a new product, system or process being created while a innovation is an improvement of an existing technological product
- 5BrainstormA group technique for solving problems, generating ideas, stimulating creative thinking, etc. by unrestrained spontaneous participation in discussion
- 6ConstraintA limit to the design process.
- 7DesignAn iterative decision-making process the produces plans by which resources are converted into products or systems that meet human needs and wants or solve problems
- 8Design BriefA written plan that identifies a problem to be solved, its criteria, and its constraints. Used to encourage thinking of all aspects of a problem before attempting a solution
- 9Engineering NotebookA book in which an engineer will document all of his/her own work that is associated with a design project
- 10PrototypeA full-scale working model used to test a design concept by making actual observations and necessary adjustments
- 11What is the order of the design process?Define Problem

Communicate the project - 18Chemical EngineeringApply scientifically the principles of chemistry, physics, and engineering to design an operation of plants for the production of materials that undergo chemical changes during their processing
- 19Civil and Construction EngineeringPlan, design, and supervise the construction of facilities in both the public and private sectors
- 20Electrical and Electronics EngineeringDeals with the motion of electrons in metals
- 21Mechanical EngineeringApply the principles of mechanics and energy to the design of machines and devices
- 22ShadingThe representation of light and shade on a sketch or map
- 23Center LineA line which defines the center of arcs, circles, or symmetrical parts
- 24Extension LineLine which represents where a dimension starts and stops
- 25Dimension LineA line which represents distance
- 26Object LineA heavy solid line used on a drawing to represent the outline of an object
- 27Construction LineLine lightly drawn lines to guide drawings other lines and shapes
- 28Hidden LineA line type that represents an edge that is not directly visible
- 29Orthographic ProjectionA method of representing three-dimensional objects on a plane having only length and breadth.
- 30Leader LineLine which indicates dimensions of arcs, circles and detail
- 31Cabinet PictorialOblique pictorial where depth is represented as half scale compared to the height and width scale
- 32Cavalier PictorialOblique pictorial where height, width, and depth are represented at full scale
- 33Pictorial SketchA sketch that shows an object's height, width, and depth in a single view
- 34Isometric SketchA form of pictorial sketch in which all three drawing axes form equal angles of 120 degrees with the plane of projection
- 35Perspective SketchA form of pictorial sketch in which vanishing points and used to provide the depth and distortion that is seen with the human eye
- 36Multi-View DrawingA drawing which contains views of an object projected onto two or more orthographic planes
- 37Oblique SketchA form of pictorial in which an object is represented as true width and height, but the depth can be any size and drawn at any angle
- 38What are the 3 spatial Dimensions?Height, width, depth
- 39Technical Working DrawingA drawing that is used to show the material, size, and shape of a product for manufacturing purposes
- 40AccuracyThe degree of closeness of measurements to the actual or accepted value
- 41Describe the difference between accuracy and precisionAccuracy is the degree of closeness of measurements of a quantity to the actual value while the precision is the degree to which repeated measurements show the same result
- 42Why do engineers generally adhere to a set of dimensions standards and guidelines?A part must be fully and correctly dimensioned and to the proper precision
- 43Why is placement for your dimensions so important?They could be able to be read clearly
- 44How can you use units to help you solve a problem?If all the Units are the same communication of shape and shape then they could be understood without confusion
- 45Why do designers need to fully dimension a part?A fully dimension part clearly communicates how the part is to be constructed
- 46What does it mean when a sketch is over dimensioned?A sketch is over dimensioned when the same measurement. dimension is on 2 or more of the views
- 47HistogramA graph of vertical bars representing the frequency distribution of a set of data
- 48StatisticsCollection of methods for planning experiments, obtaining data, organizing, summarizing, and presenting, analyzing, interpreting, and drawing conclusions based on data
- 49Standard DeviationMeasure of the spread of data values
- 50Normal DistributionA function that represents the distribution of variables as a symmetrical bell-shaped graph
- 51ModeThe value that occurs most frequently in a given data set
- 52RangeThe difference between the largest and smallest values that occur in a set of data
- 53MedianA measure of center in a set of numerical data
- 54Significant DigitsThe digits in a decimal number that carry meaning contributing to the precision or accuracy of the quantity
- 55CalipersA measuring instrument having two adjustable jaws typically used to measure distance or thickness
- 56ModelA visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original
- 57AnnotateTo add explanatory notes to a drawing
- 58ComponentA part of element of a larger whole
- 59Physical ModelA physical representation of an object. Prototypes and appearance models are physical models
- 60Gemetric ConstraintConstant, non-numerical relationships between the parts of a geometric figure,
- 61Mathematical ModelingThe process of choosing and using appropriate mathematics and statistics to analyze empirical situations, to understand them better, and to improve decisions
- 62Working DrawingDrawings that convey all of the information needed to manufacture and assemble a design
- 63What advantage do Computer Aided Design and Drafting provide over traditional paper and pencil design?The advantage of CAD is that it is easily modified, and reproducible. Usually faster to produce. Can be looked at in 3 dimensions and seen at different angles
- 64What is the difference between a mate and flush constraint?Mate sticks the surfaces together while flush aligns the surfaces on a common edge
- 65What constraint would you use to place a pin inside a hole?Insert Constraint
