2 Goals and Learning Objectives: This is the first course in a two-course ME Laboratory sequence. The course deals with sensors and basic related theory. The second course addresses complete experimental designs with regard to both hardware and statistical analysis. This course will be interesting and useful to all Mechanical Engineering students. Your feedback (both positive and negative) as the semester progresses is important. The course goals include: introduction to sensors and data acquisition systems for typical mechanical engineering applications, become familiar with common data acquisition software for acquisition (Labview), and increase in written and oral communication skills, The expected course outcomes include: explain the principles of operation of the following sensors: LVDT, accelerometer, strain gage, pressure transducer, temperature transducers, venturi flow meter, turbine flow meter, wheatstone bridge, voltmeter, ammeter, manometer; calibrate these sensors; take data with these sensors, appropriate signal conditioners, and a data acquisition system; perform a least squares curve fit; develop a simple interface using Labview, and write a clear technical report on an engineering experiment, including methods, results, uncertainty analysis, and conclusions along with formal presentations of that material. Classes: Classes will be conducted on a regularly scheduled basis. The purpose is to cover theoretical applications relating to experimentation that will be studied the following week. Attendance is required in order to successfully complete each assignment. Lab Attendance: Lab attendance is mandatory. There will be no make-up laboratories unless required due to an official closing of the school, due to weather, for example. Pre-Lab Assignments: Pre-lab problems will be assigned at lecture the week prior to conducting each experiment. Pre-labs are to be completed in your logbook and a copy of the pre-lab is due at the start of each lab. Laboratory experiments may not be performed without first completing the corresponding pre-lab assignment. Preparation / Participation: An evaluation will be conducted during each laboratory experiment to determine if appropriate preparation has been conducted for the experiment. Active participation of each student in a group is required in order to receive full credit for laboratory results. ME Lab I

3 Post-Lab Answer and Memo Reports: Reports should be written following guidelines issued separately. Reports are due one week following the lab exercise. All reports are to be typed. Hand written reports will not be accepted. Reports that are submitted late may or may not be accepted based solely on the discretion of the instructor. Reports are to be written either by each student individually or as a group effort as indicated in the lab identification section. Individual reports identified are to be your own individual efforts. Plagiarism in a lab report will result in a zero grade for that experiment. A second instance of plagiarism will result in an "F" for the course. Laboratory Notebook: Each student must maintain a formal lab notebook and record the following information in the notebook for each experiment prior to leaving the laboratory. Title, date, partners Equipment used: model and serial number Procedure (only if different from the procedure in the handout) Settings of equipment: gains, offsets, units, etc. needed to interpret raw data Raw data, if not in a diskette file Rough analysis to see if data is reasonable Note: Data log notebook will be reviewed and graded by the instructors. The lab notebook must be bound with dated and numbered pages, written in ink (no pencil), and changes appropriately countersigned. The last logbook page of each experiment must be signed by the experimenter (student) and by the TA. Post Experiment Requirements: Presentation of theoretical and experimental work is required in hard copy format. Spreadsheets and graphs should be used to properly report each analysis. All reports MUST follow procedures identified; separate documentation describes all reporting and documentation requirements. Grading: At this time, the final grades are expected to be determined using the following grading criteria: Pre-lab 10% Post-lab reports (short format) 35% Memo reports (long format) & presentation 25% Data log notebook 10% Labview Graphical User Interface developed 10% Written exams 10% ME Lab I
