4. Which of the following is commonly used in the testing and analysis of solutions?

All of the above

5. In the final solution or output stage, which of the following is used to communicate design solutions to customers and people who will make the product?

All of the above

14. ____ is a process where people communicate any idea that comes to mind.

Bainstorming

33. Software that is often used to create drawings in order to communicate design solutions.

CAD

36. Equipment used to convert drawings into 3-D shapes.

CNC

8. A ____ is a specific condition that limits the engineering design solution.

Constraint

A design ____ is a rule or principle that is used as a basis of an engineering design problem

Criteria

31. A type of technical drawing that accurately communicates size and shape, including specific dimensions.

Detail

Describe how engineering notebooks are used.

Engineers typically record all of their thoughts, ideas, sketches, calculations, designs, and more in engineering notebooks. They serve as legal documents of the design process.

True or False? 20. No records should be kept of brainstorming sessions once an engineer has decided on the design.

False

True or false? 16. The design brief outlines the problem in clear terms.

False

True or false? 18. Multiview drawings distort angles to show shapes as your eye would see them.

False

True or false? 19. Three-ring binders should be used for engineering notebooks because it is easier to remove designs that do not solve the problem.

False

What is ideation?

Ideation is the process of generating ideas.

2. Brainstorming is most effective when done ____.

In groups

11. Computer simulation is often used in testing because, compared to building real prototypes, it is ____.

Less expensive

10. Multiview drawings are also called ____ drawings.

Orthographic

A(n) ____________________often shows multiple views of the same object.

Orthographic drawing

30. A type of drawing that shows a single view of an object, but in 3-D as your eye would see it.

Pictorial

A(n) ____________________ shows a single view of an object in three dimensions.

Pictorial drawings

1. ____ is arguably the most important step in the design process because large amounts of time and money are wasted if mistakes are made at this step.

Problem definition

7. The ____outlines the problem in clear terms but is not so specific that it limits creativity in design.

Problem statement

The ____________________outlines a problem in clear terms.

Problem statement

A physical model of a final product is a(n) ____________________.

Prototype

12. ____ are physical models of final products or aspects of them.

Prototypes

32. Process of making 3-D plastic models by adding many thin layers of material until the entire shape has been created.

Rapid prototyping

34. A type of full-color drawing that shows what the object will look like.

Rendering

13. ____ show what a design will look like in a given light.

Renderings

What is reverse engineering?

Reverse engineering is examining a product or process to understand how it works in order to recreate it, improve on it, or destroy it, if needed.

35. A simple type of drawing made in the idea generation stage in order to record and communicate ideas so they can be refined further in the solution creation step.

Sketch

3. In the ____ step, all ideas are evaluated and the best one is chosen to move forward

Solution creation

What is engineering design?

The creative application of technology to design a system, product, or process to solve a given problem or meet a given need.

What information is included in a design brief?

The design brief includes criteria and constraints such as size, cost, and quality.

6. When is the engineering design process complete?

The engineering design process is never complete

True or false? 15. Engineering notebooks can be used as legal record.

True

True or false? 17. The design brief includes criteria and constraints such as size, cost, and quality.

True
