TAs:Joshua Lake, Daniel Ringle, Ryan Scott
When contacting instructors or the TAs via email please include “ME411” at the start of the subject line.
Prerequisites:Circuits–ECE 221or241 or equiv. and seniorstanding.
Description:Principles and applications of measurement methods and instrumentation techniques, as used in various engineering disciplines, are studied. Examination of general measurement concepts and instrumentation characteristics. Specific devices for measuring such parameters as displacement, force, strain, pressure, flow, temperature, motion, time, and frequency are discussed. Testing and verification of theory, design, and laboratory evaluation of mechanical components and systems are also made. Lecture and laboratory.
Course Objectives:Students who successfully complete this course will:
- gain an understanding and familiarity with modern methods and instrumentation for making engineering measurements,
- learn to analyze and communicate results of experiments,
- be able to design and implement experimental solutions to engineering problems, including static and dynamic mechanical, electrical, flow and thermal measurement
- understand the roles that cost, performance and system complexity play in the design of an instrumentation system
- be able to identify sources and types of uncertainty, combination and propagation of uncertainties, and application of appropriate statistical models for uncertainty analysis.
Late Policy:As a general rule, late assignments will not be accepted.
Labs:Students will work in groups (of their choosing) of2 or 3 on laboratory assignments.
COMPONENTS OF YOUR GRADE:
HW:HomeWork assignments (denoted HW1, HW2, etc) are to be completedindividually by every studentmust be your own work and are due at the beginning of the class period. Homework should be completed neatly on lined, graph, or engineering paper. All answers should be circled/labeled.
LA:LabAssignments (denoted LA1, LA2, etc) are to be completedby each lab group and are due at the end of the lab in which they are assigned. These typically involve a check-off sheet that the TA or lab instructor will complete for each group. Specifically, if the assignment is to create a Labview “virtual instrument” with certain features the group will need to demonstrate these features for the instructor.
REPORTS:Experiments (denoted EXPT1, etc) will require group reports, generally due the week after the experiment. These reports are to be stapled NOT bound. Each report must contain a title page that indicates, title, date, group member names, a description of the workload division, and the name of the class. Reports (not including the title page, and any appendices) must be no longer than 7 pages(11pt or larger font, line spacing of 2.0). Figures/Tables are included in this limit. Every report should contain Introduction, Methods, Results/Discussion, Summary/Conclusion sections (actual names of sections can vary). A sample (no more than 2 pages) of carefully documented raw data should be included if appropriate) as an appendix. All pages must be numbered. All figures/tables must be numbered, referred to in the text, and have complete captions. See the link to the course website at for further guidelines and a grading template.
FINAL REPORTS:
Groups will design and conduct final experiments as a team, and continue to work as a team on data analysis and report writing. These teams MAY be different than the teams constituted for the other laboratory assignments and do not need to be limited to a single lab section (as long as team members can find suitable time slots to work together on the final project). Each ME411 team will turn in a single groupfinal report for this project.
The report format should conform to that described above under REPORTS, but can be up to 12 pages in length (including figures/table, but excluding the title page and raw data appendices). Again, please DO NOT BIND your reports.
EXAM:An exam will be givennear the end of the term in the regular class meeting. This exam will be comprehensive covering topics discussed in lecture, homework assignments, and principles learned in the lab. It will be a closed book exam, but students can bring 1 one-sided 8 ½ by 11 inch sheet of notes. There will be NO final exam during the university-scheduled exam period.
