MIDTERM IED REVIEW GUIDE

A group of students decided to design a device to store their gum during class, so that they can chew it again later. During the Generate Concepts phase they brainstormed ideas to solve this problem. Select from the list below the three effective brainstorming techniques they may have used: a. Write down every idea b. Wild ideas are encouraged c. Build off the ideas of others d. When describing your idea take as much time as needed and explain in full detail e. Criticism is allowed f. Quality ideas are most important.

• Write down every idea

• Wild ideas are encouraged

• Criticism is allowed

• Build off the ideas of others

• When describing your idea take as much time as needed and explain in full detail

What tool should the students use to decide which gum storage device to develop?

• Decision Matrix

• Design Brief

• Test Report

• Iteration

A group of students decided to design a device to store their gum during class, so that they can chew it again later. The student group decides to interview current and past Intro to Engineering students to help them identify the criteria for their gum storage device. From this they develop a design brief for the project. Choose the best answer that matches which step of the design process that is being described.

• Define the Problem

• Develop the Solution

• Evaluate the Solution

• Develop and Test the Prototype

What type of hole is noted on the drawing? Select all that apply:

• Counterbore

• Countersink

• Simple

• Through

• Blind

The engineers decide the hole depth needs to have a Bilateral Tolerance of 0.03. Which of the dimensions accurately reflects this change?

• Ø 0.2 ↑↓ 0.03
