Oakes; Problems:

1. 7.7- Measure the height of your class building using two different methods. Which is
more accurate? – Option 1: You need to estimate the height of the observatory adjacent to
Research Hall just north of the Nguyen School of Engineering. Use two different estimation
methods as discussed in class. (2 points)
• Use the following information to solve the problem: When seeing the top of the observatory a 45
degree angle, your approximate distance to the center of the observatory is ~100 feet. Each floor

Option 2 – Find a multi-story building on your own that’s near you, and use the estimation
techniques we discussed in class to estimate its height. Please include a digital picture of it in
your HW Word or pdf document.
2. 7.9 – How high do the letters on an expressway sign need to be readable? Make some
reasonable assumptions, e.g., if you can read ¼” letters at 2’ from the computer screen, how large should
the letters be at 200’ and be readable? (1 point)
3. 7.42 – Select one of your classes. How could that class be more effective in helping you learn? focus
answer on ENGR 107-001. (1 point)
4. 12.3a,c,e Develop a list of working criteria that could be used in deciding whether to:
a) Accept a co-op job offer from Company A or Company B.

e) Change your major or remain in engineering. (2 points)

1. 12.4 Identify five product, structure, or system designs you think can be improved. Pick
one and write a preliminary problem statement for the engineering design process. (2 points)
2. 12.7 Identify five product, structure, or system designs you think can be improved. Pick
one and write a preliminary problem statement for the engineering design process. – Develop a decision
table for one of the items you listed in Problem 12.4 (filled out and totaled). Which alternative
the solution is best? (2 points)
(See sample tables on pages 348 and 369 of text)
Now run the following code (copy-and-paste it) after the “>>” (command) prompt:
x = [0:5:100];
y = x;
plot(x, y)
Copy-and-paste the plot onto your HW solutions page. (1 point)
