Prof. Park: Monday and Wednesday: 1:00 – 3:00 if not in lab. Textbook “Experimental Solid Mechanics,” A. Shukla and J. W. Dally, College
Enterprises, 2010. Articles and documents uploaded to SAKAI during class Grading First four assigned lab reports: 12 % each (48% total)
Formal report for Lab 5: 20 % (Presentation: 5 %, Report: 15%) Two exams: 10% each (20% total) Homework: 12% Course Policy Five (5) labs will be conducted during the semester. Two (2) solid mechanics labs supervised by Prof. Shukla, and two (2) thermal/fluid/nano science labs supervised by Prof. Park. Each lab will be performed in groups of three (3) to five (5) students as assigned by the instructors on the first day of class. Handouts for each lab topic will be available on the SAKAI site for MCE 414. Students are required to read the handouts before coming to class and/or to the lab.
An additional lab will be conducted that will be selected by each group from some subject of interest to them. Having gained sufficient experience in MCE-313, and from the laboratories conducted in the present course, the students are expected to make up a lab hand-out on the chosen topic, conduct the experiment, and write the accompanying formal report. Access to the laboratory must be coordinated with the instructors and the teaching assistants for this last experiment. You will have 4 weeks (Nov. 14 through Dec. 9) to perform this experiment. Please start early. In addition, we would like to have a balance of solid mechanics and Thermal/fluid/nano sciences. Once half of the groups have chosen experiments in a particular field, no more will be allowed in that field of study. You are, therefore, encouraged to select and submit early, so you have your desired choice. Each group is to submit its choice for lab 5 by the fifth week of class (Wednesday, October 12) so that additional laboratory supplies can be purchased, if needed. In the last week, all groups will have a five-minute presentation on their Lab5 results. The due date of the Lab5 report is December 16 (Friday). The lab reports will be written and submitted as a group, per instructions given in class. The report for the fifth experiment will be a full “formal” report. Reports are due within two weeks
(14 days) of performing an experiment. A hard copy is to be handed to the appropriate instructor. Late reports will incur a penalty of 10% for every day it is late. All Lab reports, including Lab 5, will be graded as a group effort. Lab groups will have a leader for each experiment. The leader is to consult with the appropriate instructor after each experiment and present him with the ongoing write-up, tables, and plots related to the experiment. This is to make sure that you understand what is required in each experiment and to ensure that only correct results are included in the each report. The leader should report the role and contribution of each member in detail. Based on the contribution, the leader should grade each team member (letter grade: A to D), and team members should sign the form in agreement. The instructors will seriously take into account the leader’s evaluation when grading the team performance and grading team members. Attendance is mandatory for all assigned lectures and labs. Students who do not attend a lab session will not receive a grade for the corresponding report. An exception will be made if the lab was missed for a medical reason (Doctor’s letter needed). No excuses such as forgetfulness will be allowed. An arrangement must be made with the instructor to make up the lab and to participate in the writing of the report. Class attendance will not receive a formal grade but will contribute to the final student assessment in the course. For instance, a student on the borderline between two grades may be edged up to the higher grade based on a good attendance record and vice-versa. Any student with a documented disability is welcome to contact either professor early in the semester so that we may work out reasonable accommodations to support your success in this course. The student should also contact Disability Services for Students, Office of Student Life, 330 Memorial Union, (401) 874-2098. Planned Labs
