First week
(Jan 11-15) - Introduction, standards, calibration
Use the checklist for Worksheet 1 (all problems) placing check marks in each cell (to the left of the dashed line) to confirm you have completed each item for each problem. SUBMIT this next week as part of Worksheet 1.
Need Help? See Writing for Engineers for help (Communications and display of data - Part 1) and links at the Mechanical Engineering Student Reference Materials page. Of course, you can come talk to the instructors as well.
You will be creating a number of graphs for this assignment (and future assignments). You may use Excel or MatLAB to create the graphs. Regardless of software, graphs must be of professional quality appropriate for professional reports.

Worksheet 1 is due next week: Download the worksheet
Down checklist for Worksheet 1
Down load data: data for Worksheet 1
PLEASE open this link and follow the directions to complete Problem 1 on the worksheet! This will help you learn to use Excel to create appropriate graphs. If you use MatLAB, then this won't help much.
For Problems 2 through 6, you should work on the graphs on your own, and then look at the "solutions" (solutions), otherwise you will not learn what you need to learn for later on this semester and future classes - points will not be deducted on this assignment if your graphs (for problems 2-6) are different than the solutions - it is more important that you create them and that you put thought into them than it is for them to look like the solutions!!!
If you need basic help with Excel, start here, then ask for help.

FOR HELP with creating graphs (the following links are also on the Mechanical Engineering Student Reference Page
Graphing of Engineering Data
Graphing/Figure Standards


Standards (powerpoint)

Triple Point video part I
(in the video, watch at least from the 30 sec mark to the 4:30 mark)
Triple Point video part II (watch through the 1:30 mark)
Watch the following from about 40-60 seconds onward:
The kelvin
The kilogram
The meter
The second
Caliper Calibration Data


Week 2
(week of January 18) more calibration and standards
Assignment (due in one week - at the beginning of your lab section): Independent laboratory background writeup (one per group) - see UP Writing for Engineers for information on writing "background." Click here for description of experiments and requirements.
Click here for help with using ASTM books - how to read/use the Index
ASM Handbooks, knovel

Standards - don't reinvent the wheel - SAE has already done this for you.
Example of a test standard

Week 3 (week of January 25) strain gages, load cells
Assignment due next week in lab - complete the worksheets in both of the following modules (includes graphs, tables and discussions):
Bending module
Load Cell module

Field Calibration (7 min)
Daily and annual calibration (as applied to color measurement) (4 min)
More information on calibration can be found: Mechanical Engineering Laboratory Handbook
777 Wing Test (with Rubber Ducky)


Week 4
(week of February 1) tensile testing
Assignment: technical letter (Tensile testing). For details read the letter from the instructor to the class describing what is due next week (might want to read this, hint, hint - not only does it describe what is required, it provides an example of a professional letter).
For help writing letters: UP's Writing for Engineers for description of technical letters, see links for writing at the Mechanical Engineering Student Reference Materials page, or contact the University's Writing Center.
Prelab presentation for tensile testing (for reference only) (ppt)
DOWN LOADS for this week's assignement:
Down load test data
(to be used as data for the letter)
Check list for memos and letters (to be included with all memos and letters in EGR270)
Check lists for graphs (to be included with all graphs in EGR270)
Photos from the lab itself (for insertion into the technical letter)
HINT, CLICK HERE for a possibly (probably!) good reference to include in the background of your letter

PRINT AND STAPLE your work the NIGHT BEFORE it is due at the latest. Otherwise, eventualy, a malfunctioning printer will cause the assignment to be late. So sad.

FYI, photos of tiny broken wires with "cup and cone" fracture (courtesy of Noah Kolarsky and Ian Collier)
Tensile Test post-lab


Week 5 (week of February 8)
cold rolling and annealing of copper
Assignment. Two items due next week: Independent laboratory's experiment plan (draft, submit as a small group) and the worksheet from todays lab (individual work to be submitted).
CLICK HERE for the worksheet and the instructors letter to you for this week's strain hardening and annealing lab. (Note: checklists to be turned in with graphs are linked at the top of this page).
Photographs for cold worked and annealing lab
Textbook Image for the lab (worth looking for educational reasons)
Click here for description of independent lab and requirements. - also see Section IV of Mechanical Engineering Laboratory booklet. Please resubmit the marked up purpose/background returned to you along with an appropriately re-written purpose statement and background (and newly created test plan draft).

Week 6 (week of February 15) - Precipitation HT of 2024 aluminum
Next week, Quiz 1 will be administered during labs. Quiz topics: calibration and measurment standards, standardized tests, tensile test, copper coldworking/annealing. There will be 7 questions selected from: POTENTIAL QUIZ QUESTIONS FOR ALL QUIZZES THIS SEMESTER
Technical letter due next week on heat treating of 2024 aluminum alloy. Include the two checklists attached to the front of the letter:
Check list for memos and letters (to be included with all memos and letters in EGR270)
Check lists for graphs (to be included with all graphs in EGR270)
Reference information might include: aluminum-copper alloy phase diagram ; ASM Handbooks, on-line


Aging characteristics of alloy 2024 sheet (ASM Handbook, Volume 4). Note, hardness and tensile strength are directly related (but are not the same thing). The data was recorded at ROOM TEMPERATURE - after exposure to various temperatures/times; therefore, the changes in strength are due to changes in the microstructure (such as aging and overaging).

Rockwell B scale hardness data from long duration aging (for a material with hardness of 56 on the Rockwell B scale it is written as 56 HRB):

Week 7
(Week of February 22) Jominy end-quench testing (heat treating of steel)
Quiz 1 will be given in labs sections this week.
READ BEFORE LAB (Click here) the letter from the instructor to students for this week.
Assignment #1- as a team, for the Independent Lab:
a) Revise the background and procedures per instructor feedback.
b) Create a blank data sheet for your experiment. As examples, consider the data sheets provided to you before each lab we've done this semester and: click here for further details regarding creation of blank data sheets.
c) Submit the previous Independent Lab work that contains instructor feedback/comments.
Click here for description of independent lab and requirements.
