Engineering Chapters 4-5
| Question | Answer |
|---|---|
| What is research? | This is a scientific way to discover facts about a certain topic or solution. |
| When are rough sketches normally developed? | They are during brainstorming or immediately after. |
| In this step of the sketching process, the engineer is concerned with the appearance and functionality of the object. | visualize the solution |
| This is the basic shape of the object. | outline |
| Library research is this type of research. | This uses different forms of printed and digital materials. |
| Which method of research involves engineers seeing technology in action? | field visits |
| What four considerations are engineers interested in when performing experimental research? | material testing, feasibility study, production research, and effectiveness research |
| When is a potential solution feasibility considered most important? | It is most important during the research stages. |
| Engineers analyze a solution's ____ by looking at the advantages and disadvantages to create a chart. | trade off |
| These sketches combine all the components of the final design. | refined sketches |
| Why is communicating a solution important? | It is important so that everyone can understand what has been done. |
| Explain the difference between a detail drawing and an assembly drawing. | A detail drawing shows the exact shape and size of an object. An assembly drawing shows how different parts fit together to create the entire object. |
| How is a schematic drawing used? | They are used to show how different parts are connected together to form a system. |
| Explain when you would use a one view drawing. | It is used to show flat pieces. |
| Explain when you would use a two view drawing. | It is used to show cylindrical objects and objects with a round shape. |
| Explain when you would use a three view drawing. | It is used for rectangular objects. |
| What is visualization? | ability to mentally see a representation of a product for which there is no physical object |
| This type of drawing is used to communicate a design to someone who does not understand isometric drawings. | pictorial drawings |
| Which type of drawing do engineers use to highlight one feature of an object? | oblique drawings |
| What does a perspective drawing show? | It is used to show an object from a specific point of view. |
| Symbols are regularly used in _______ drawings to represent different parts of an electric or hydraulic circuit. | schematic |
| What are two major organizations that develop symbols for use throughout different engineering disciplines? | ANSI and ISO |
| Why are construction lines used? | They are used as reference points |
| Why are hidden lines used? | They are used to show parts of the drawing that are hidden from sight. |
| Why are center lines used? | They are used to show the center point of the object. |
| Why are border lines used? | They are used to create a border around the edge of the paper. |
| Explain the differences between dimension lines and extension lines. | dimension lines are drawn between extension lines and have arrows at the end of each line. Extension lines are drawn from very near the edge of the object to outside the view. |
| List three different types of dimensions. | size, location and shape |
| What is a leader? | It is a line with an arrow on the end pointing to the feature. |
