2012 – 2013 PLTW IED End of Course Exam
Section I Review
Directions: This is a review for the end of course assessment. You will take two 40 minute tests
online using only the PLTW Engineering Formula sheet. The test is designed for 50% of students
to get 50% of the questions correct. You grade will be based on the class average = 85%. It is a
20 point assignment. Answer each of the following questions by finding the information in the
PLTW Power Point slides.
1. Write a design statement.
2. Create some design constraints from your statement.
3. List the possible Deliverables in regards to #1 and 2
4. What are typical Engineering notebook contents and recommended practices?
5. Draw and dimension a tube then calculate the volume.
6. Draw the diameter and radius symbol used in dimensioning?
7. What is the difference between precision and accuracy?
8. What is information is collected during a functional analysis during reverse engineering
9. Calculate the arithmetic mean of the given data set? (3,9,11,8)
10. Sketch the appearance and define the use of object lines / hidden lines / section lines /
construction lines
11. What is the purpose/process of creating a decision matrix, researching and develop ideas,
creating CAD model, construct and test a prototype
12. Sketch a sectional view and auxiliary view.
13. Write a tolerance and list the range of acceptable sizes.
14. What are the four types of tolerances have on reading dimensions?
15. What is a Gantt chart?
16. Define visual design elements rhythm, balance, proportion, etc.
17. What is the process called of analyzing the products aesthetics, function, and structure?
18. What is determined during a structural analysis?
19. What are some typical group norms - best guidelines, protocols, and rules of conduct for a
team?
20. Draw a dimension both a rectangular prism and a cylinder. Calculate surface area of both.
21. What is the difference between a scaled model vs. mock up vs. prototype?
22. What information is listed on design brief contain? What is it’s purpose.
23. What does a technical report contain?
24. Sketch an isometric / two point perspective / oblique / orthographic. Label key elements of
each drawing.
Section II Review
25. Sketch a rectangle with a hole located inside the
perimeter. Add the three dimensions needed and
label them as size or location dimensions.
26. Given an example of what a team of engineers might
be doing at each stage of the design process.

volume of 100 milliliters.
34. How many degrees of freedom does an rectangular prism have if it is mated to the horizontal
work plane? How many dof does it have with no constraints?

How many quarts are needed to paint 1,000 objects?
37. List the basic rules for a session of brainstorming with your peers?
38. Give an example of what information is collected during the structural, visual, and functional
analysis of reverse engineering.
39. What a sample hole notation for a flat head machine screw and describe what the numbers
mean.
40. Give an example of a project that each of the following engineers might perform: chemical,
mechanical, electrical, civil.
