1-1) Draw a conceptual sketch of your computer. Identify the keyboard, screen, power

source, and information storage devices using arrows and labels.

Note: Eventually we will show you (if you don’t know already) how to draw a decently

formatted sketch on your computer. Meanwhile this crude representation will suffice!

1-2) Draw a conceptual sketch of an incandescent light bulb. Identify all the components

using arrows and numbers as in Figure 1.1.

1-3) Draw a conceptual sketch of a ballpoint pen. Identify all the components with arrows

and labels as in Figure 1.2 of this chapter.

1-6) Repeat Example 1.3 using the NSPE Code of Engineering Ethics. Solve using the

Engineering Ethics Matrix.

(Example 1.3: An Ethical Situation

You and your roommate are both enrolled in the same engineering class. Your

roommate spent the weekend partying and did not do the homework that is due on

Monday. You did the homework, and your roommate asks to see it. You are afraid he or

she will just copy it and turn it in as his or her own work. What are you ethically

obligated to do?

a. Show your roommate the homework.

b. Show the homework but ask your roommate not to copy it.

c. Show the homework and tell the roommate that if the homework is copied, you will

tell the professor.

d. Refuse to show the homework.

e. Refuse to show the homework but offer to spend time tutoring the roommate.)

Of course, it may be possible to find a code of professional ethics that will lead to a

contrary opinion to another code, but as per the solution in the text for Example 1.3, this

code of professional ethics favors the same solutions, namely d & e.

1-7) Repeat Example 1.4 using the Five Cornerstones of Ethical Behavior. Solve using

the Engineering Ethics Matrix

(Example 1.4

You are a civil engineer on a team designing a bridge for a state government. Your team

submits what you believe to be the best design by all criteria, at a cost that is within the

limits originally set. However, some months later the state undergoes a budget crisis.

Your supervisor, also a qualified civil engineer, makes design changes to achieve cost

reduction that he or she believes will not compromise the safety of the bridge. You are

not so sure, though you cannot conclusively demonstrate a safety hazard. You request

that a new safety analysis be done. Your supervisor denies your request on the grounds of

time and limited budget. What do you do?)

1-8) It is the last semester of your senior year and you are anxious to get an exciting

electrical engineering position in a major company. You accept a position from company

A early in the recruiting process, but continue to interview hoping for a better offer. Then

your dream job offer comes along from company B. More salary, better company, more

options for advancement, it is just what you have been looking for. What should you do?

a. Just don’t show up for work at company A.

b. Send a letter to A retracting your job acceptance with them.

c. Ask company B to contact company A and tell them you won’t be working for

them.

d. Reject the offer from company B and work for company A anyway.

would retract

if offered by

B

The “best” answer is to reject the offer from Company B; however, the real message here

is to be upfront with company A while provisionally accepting their offer saying you

reserve the right to go to Company B.

1-9) A company purchased an expensive computer program for your summer job with

them. The license agreement states that you can make a backup copy, but you can only

use the program on one computer at a time. Your senior design course professor would

like you to use the program for your senior design project. What should you do?

a. Give the program to your professor and let him/her worry about the consequences.

b. Copy the program and use it because no one will know.

c. Ask your supervisor at the company that purchased the program if you can use it at

school on your senior project.

d. Ask your professor to contact the company and ask for permission to use the

program at school.
