Course Goals

Opening the upper-level laboratory sequence in Mechanical Engineering, this course introduces students to contemporary techniques for data acquisition and analysis, focusing on measurements commonly made by mechanical engineers. Students measure quantities like force, position, velocity, temperature, flow rate, elastic modulus, and viscosity. Students learn about analog and digital signals, frequency analysis, measurement system models, statistics and uncertainty analysis, filters, sampling, and data visualization. Matlab is the primary software environment for acquisition and analysis.

Successful students in this course will also gain

Prerequisites

Materials

Sharing material generated for this course by the instructor is prohibited.

Assignments & Grading

All assignments and activities associated with this course must be performed in accordance with the University of Rochester's Academic Honesty Policy. In this course, students are allowed to collaborate on homework and laboratory reports — provided that each collaborator takes the time to fully understand the material, then write and submit their own assignment. Services like Chegg.com are uniformly prohibited. Facilitating dishonesty is dishonesty. Procrastination is a major source of dishonesty, so start assignments early and keep yourself organized. On quizzes and exams, neither collaboration nor outside aids are permitted unless the instructor explicitly states otherwise. Students must write and sign the Honor Pledge on all exams: “I affirm that I will not give or receive any unauthorized help on this exam, and that all work will be my own.”

Reading Quizzes - 5%
Each lab exercise will begin with a reading quiz consisting of three short questions taken directly from the procedure for that lab exercise.
Lab reports - 50%
Lab reports are to be submitted via GradeScope, due at the end of the Friday of the subsequent week, except for the last lab report, which is due at the end of the last day of class. Late submissions will not be accepted.
Homework - 10%
Homework is to be submitted via GradeScope, due 15 minutes before the beginning of your lecture section. Late submissions will not be accepted.
Midterm exam - 15%
One midterm exam will take place in person, in lecture sessions, during the week of 31 October.
Final exam - 20%
Cumulative. In person, 19 December 16:00-19:00, Hoyt Auditorium.
All assignments will be graded using GradeScope, and regrade requests will be handled through the GradeScope interface. Each student's work will be graded anonymously and by different people as the course proceeds.

Feedback & Availability

I will distribute evaluations periodically to collect feedback. Announcements will occasionally be made by email. I typically check email frequently but cannot guarantee immediate response at all times. Quick questions can be effectively and efficiently addressed by email, but for in-depth questions a face-to-face discussion usually works better, so consider requesting a meeting. Or, when classes are in session, come to office hours:

Time Location Instructor
Mondays 15:30-16:30 Hopeman 218 Doug Kelley
Tuesdays 14:00-15:00 Hopeman 215 Anushika Athauda
Wednesdays 16:00-17:00 Hopeman 215 Anushika Athauda
Thursdays 11:00-12:00 Hopeman 112 Athan Sanders
Fridays 11:00-12:00 Hopeman 305 Keelin Quirk
