| Question | Answer |
|---|---|
| What are the six steps of the engineering design process? | Define Problem, Generate Concepts, Develop Solution, Construct and Test, Evaluate Solution, Present Solution |
| What are the deliverables for each engineering design step? | Design Brief, Design Matrix, Technical Sketches, CAD model, Project Recommendations, Formal Presentation |
| What are the main elements to a design brief? | Client, Target Customer, Designer, Problem Statement, Design Statement, Criteria, Constraints |
| Name of the view when you look at an object from a single, straight on view? | Orthographic |
| What is the difference between precision and accuracy? | Precision is consistent values whereas accuracy is how close you are to the target value. |
| Why is it important to collect mathematical data on a product or object you create? | The collected data can be used to make necessary adjustments to the created object. |
| What are the four guidelines for selecting the front view of an object? | 1.) Shows the longest dimension 2.) Shows the best shape and characteristic contours 3.) Hides the fewest (hidden) edges and features 4.) Displays the most stable and natural position |
| Why is it important to shade an isometric sketch? | Makes the sketch more realistic |
| When creating a multiview drawing of an object, what views are typically shown? Where are they placed? | Top Isometric Front Right Side |
| What is the name of the page used in Fusion 360 to show multiviews of an object? | Title Block |
| What kind of line is used to define the center of arcs, circles, or symmetrical parts? | Centerline |
| What kind of line is used to define an edge of an object not directly visible? | Hiddenline |
| What are the two types of constraints used in CAD software? | Geometric, Dimensional |
| Name two geometric constraints that you use in Fusion 360. | Parallel, vertical, perpendicular, horizontal, coincident, equal |
| What are the two main methods of constructing objects in any CAD program? | Additive, Subtractive |
| What is a sectional view? | A view from the inside of an object. |
| What are the 3 types of tolerances? How can you identify them? | Unilateral, Bilateral, Limit Dimension Use separate + and - sign, ± symbol, has no signs |
| The more precise the part needs to be machined, the ____ expensive it will be to produce. | More |
| List 2 reasons why reverse engineering is used. | Collect documentation for a product, machine, or building that has been lost, destroyed, never formalized, or must be transferred to a new form—such as a computer 3D model. Model a product for analysis and testing. |
| List 2 elements and 2 principles of visual design. | Line, color, value, shape, form, space, texture. Balance, emphasis, contrast, rhythm, proportion, unity, economy |
| What is a black box and what is its purpose? | It is a functional analysis tool that identifies the inputs and outputs of a system function. |
| List 5 different properties of engineering materials. | Density, yield strength, tensile strength, elasticity, hardness, electrical conductivity, thermal conductivity |
| What are the 3 elements of sustainable design? | Society, environment, economy |
| What are the 3 phases of human-centered design? | Inspiration, ideation, implementation |
| What are the 6 kinds of simple machines? | Lever, wheel and axle, pulley, wedge, inclined plane, screw |
