Assigned in week of Tu, 01/16/01 (Due as per rules if not specified otherwise):1) Lab Safety Rules and Our First Lab:
We are starting with our labs on as announced in class. Attendance is mandatory for all students, and without full lab attendance your grade will be incomplete, which may result in unsatisfactory final grade and repetition of the course.
As discussed in the class, during our work in the laboratories, there is a risk of injury and/or damage to the equipment. That is why you are requested to be careful and responsible and to use a good judgments and common sense, as well as to follow all written and verbally given safety rules.
The Lab Safety Rules are posted on our class Web site [ http://www.kostic.niu.edu/LabSafetyRules.html ]. You have to print, read and understand them before doing any work in the lab. You have to send me a confirmation e-mail that "you have read, understood and will obey all Lab safety rules". You will be asked to sign the same statement before starting any work in our Labs. Please, review the Lab Safety Rules and discuss your concerns if any with me or TA before signing the above statement.
Have a safe, productive and satisfying work in our Labs!
Our First Lab (on Th, 1/25/01) and your Lab Assignment (Due Tu, 1/23/01): POSTPONED FOR NEXT WEEK!
NOTE 1 ABOUT THE LAB EXPERIMENT: You must finish experiment in the lab at least one day before the next scheduled experiment (usually 6 calendar days, afterwards the lab setup may be disassembled in order to prepare new experiment's setup). Your previous Lab assignment and Lab report are due on the day, but before the demonstration of the next Lab, or in a week time period. It is the best for you if you do your lab experiments right after the demonstration while TA is still in the Lab.
NOTE 2 ABOUT THE LAB REPORT: As explained in class and lab, you have to perform every demonstrated experiment individually as a homework assignment, calculate results (show work for each characteristic sample with units) and submit the corresponding lab report, as per related handout and posted and verbal instructions by TA and Instructor. There is no formal format for the lab reports and esthetics is not important, but neatness and substance are. In addition to required calculation and presentation of results in tabular and graphical form, you should be very specific and write as little as necessary, like key words and titles and short paragraphs for peculiar comments and conclusions. Avoid unnecessary general or repetitive descriptions from the handouts and references, but make specific reference to appropriate source instead.
2) You will be shown different general-type and bench-top instruments, and our lab equipment. Your assignment is to list 10(ten) different instruments which you saw in our Lab (EB 254). Give specific and detail names including make and model if available. Give brief description and specifications of one listed instrument of your choice (half page length and sketch/photo recommended). For most instruments you will find description in our Textbook or you could use other references from library, Internet, manufacturers' catalogs, anything you want. If specification is not available, use your best judgement to estimate it, like instrument range, precision, accuracy, etc.
After you sign the form of "Understanding and Agreeing with the Lab Safety Rules" you may go back to the Lab and scout/explore for the instruments for your assignment, but remember to always follow our Safety Rules.
3) Study the handout for our next lab: Oscilloscope demonstration, also Sec.6.3-Oscilloscope, Text p.224-228, and be ready to discuss related matters with our Lab Teaching Assistant or me.
NOTE:
Your previous Lab assignment and Lab report are due on the day before the demonstration of the next Lab or in a week time period. It is the best for you if you do your lab experiments right after the demonstration while TA is still in the Lab or Instructor.4) Study thoroughly Chapter 1, p.1-29 in our Textbook (See also Lecture Notes) (also PDF format and Animated Part) and do Problems: 1.8; 1.18; 1.28; 1.38.

Homework No. 10: Assigned in week of Tu, 03/20/01 (Due as per rules if not specified otherwise):
NOTE 1:
"Electrical devices and signal processing" topic is described in Chapter 6 (p. 192-230) of our Textbook. It is a summary of analog electrical devices for the current, voltage, and resistance measurements, as well as analog signal conditioning (amplifiers, filters, etc.). Also, the loading errors, impedance matching, grounding, shielding and wiring are described. Since you have covered these topics in more details in ELE 210, Engineering Circuit Analysis I, and ELE 215, Electronic Instrumentation courses, we are not covering this chapter formally, but will use its content as needed in lab experiments and Data Acquisition topic. Therefore, review this chapter on your own and as needed.1) Email to me your mid-semester feed-back about the lectures, labs, homeworks and midterm experiences so far. Your constructive comments and criticism will be very valuable for future improvements. Please comment the following:
(a) Material/topics that you found interesting or valuable:
(b) Material/topics that you found to have little interest or value:
(c) Your comments about Internet and multimedia usage and suggestions for course delivery improvement:
(d) Your comments about lectures, labs, assignments, instructor and TA meetings, and suggestions for course delivery improvement:
(e) Additional comments:
2) Study thoroughly Chapter 7, p.235-278 in our Textbook (See also Lecture Notes) and be ready for discussion of the subject matter. Redo the following even numbered Examples (2,4,6, and 8)
3) Study the handout for our next week lab, Measurements of motor-flywheel characteristics and be ready to discuss related matters with our Lab Teaching Assistant. You have to do the Lab's PART ONE &THREE by yourself while taking the results from the PART TWO obtained together with TA during the Lab demonstration. It is the best for you if you do your lab experiments right after the demonstration while TA is still in the Lab. Also, you have to perform the uncertainty analysis for every experimental lab and include it in your lab report. This is a more challenging lab than the previous ones (we expect that you do it more thoroughly). It will carry three times more credit than our standard labs.
NOTE: The related lab, LabVIEW and Data Acquisition (DAQ), is postponed until the hardware system upgrade is completed, hopefully in couple of weeks.
REMINDERS:
1) As explained in class, the first draft of the project progress report (no special format at this stage) will be due one week after the Spring Break (first lecture next week).
2) Study the handout for our this week lab, Measurements of flow rate and specific heat of air and be ready to discuss related matters with our Lab Teaching Assistant.
Homework No. 11: Assigned in week of Tu, 03/27/01 (Due as per rules if not specified otherwise):
Homework No. 12: Assigned in week of Tu, 04/03/01 (Due as per rules if not specified otherwise):
NOTE:
Your previous Lab assignment and Lab report are due on our next lecture. Your last Lab assignment Measurements of motor-flywheel characteristics and Lab report are due one week after the TA's demonstration of the lab. You have to do the Lab's PART ONE &THREE by yourself while taking the results from the PART TWO obtained together with TA during the Lab demonstration. It is the best for you if you do your lab experiments right after the demonstration while TA is still in the Lab. Also, you have to perform the uncertainty analysis for every experimental lab and include it in your lab report. This is the last and a more challenging lab than the previous ones (we expect that you do it more thoroughly). It will carry tree times more credit than our standard labs.REMINDER:

Homework No. 15: Assigned in week of Tu, 04/24/01 (Due as per rules if not specified otherwise):
Study thoroughly Section 12.1 to 12.10, p. 466-504 in our Textbook and redo Example 12.1 & 3. Some of the instruments in Sec. 12.2, Dimensional Measurements: Metrology (not Meteorology) were shown and discussed in our First Lab, Demonstration of different bench-top measuring instruments, like Vernier calipers, micrometers, and dial indicators. Pay special attention to Sec. 12.3, Displacement Measurements, in particular the Linear Variable Differential Transformer (LVDT). Mass measurements (balances) are in Sec. 12.4. The accelerometers, used as seismic, shock and vibration transducers, are covered in Sec. 12.5, while velocity measurements is accomplished either through displacement rate measurements in time, or through integration of acceleration measurement in time, see Sec. 12.6. The stroboscope, a " blinking" light instrument for angular velocity measurements is described in the same section, and used in our Measurements of motor-flywheel characteristics lab (for bonus credit you may submit the challenge problem to derive strobe formula as specified in the lab handout). Force measurements and the load cells are covered in Sec. 12.7, while the torque (see again our Lab) and mechanical power measurements are covered in the last part of the Chapter.
