. In engineering, the design process begins when…

a. information about an existing product is gathered by an engineer

b. an engineering design team comes up with ideas for a new product

c. a design engineer recognizes the need for a solution to a problem

2. Identifying the “target population” or “target audience” occurs during which step of the engineering

design loop?

a. Identify the Need

b. Research the Problem

c. Develop Possible Solutions

3. Engineers must understand the difference between requirements and constraints. Let’s say a team of

engineers is asked to design a pair of kids’ tennis shoes for less than $20. They determine that the only

way to manufacture shoes for this price is to use recycled materials. What is the team’s constraint?

a. The shoes must be designed for kids

b. The shoes must be made out of recycled materials

c. The shoes must cost less than $20 to manufacture

4. During a brainstorming session we want to focus more on:

a. quantity of ideas rather than quality

b. quality of ideas rather than quantity

5. Which step of the engineering design loop distinguishes an engineer from a technician?

a. Construct a Prototype

b. Test and Evaluate a Prototype

c. Redesign

6. Although the terms “model” and “prototype” are often used interchangeably, they are not the same

thing. A _______ is used to test different aspects of a product before the design is finalized. A ______ is

used to demonstrate or explain how a product will look or function.

a. model, prototype

b. prototype, model

7. When following the engineering design loop, the different stages can occur in which direction?

a. clockwise

b. counter-clockwise

c. both clockwise and counter-clockwise

d. in any direction, including shortcuts

8. The engineering design process is iterative. This allows engineers to…

a. become proficient at different engineering software applications

b. find the most optimal solution to a design problem

c. Incorporate both math and science concepts into a design problem

9. When finding the solution to an engineering design problem, there is/are usually…

a. only one possible correct solution

b. a very limited number of possible correct solutions

c. many possible correct solutions

10. The density function of repairing a machine is given by where is repair time in hours. The probability that the repair time is more than 2 hours is.

11. Consider the function f(x) = x2 – x – 2. The maximum value of f(x) in the closed interval [–4, 4] is:

12. Let a function then,
