HOMEWORK

PLACE ALL OF THE ASSIGNED AUTHOR's EXAMPLES AND SOLVED PROBLEMS INTO A THREE-RING NOTEBOOK and/or save in ELECTRONIC VERSION. The instructor will ask you to submit several of those problems - randomly chosen - for grading at each exam.

Good faith collaboration on the homework assignments is encouraged. In good faith collaboration, students should first make serious attempts to solve the problems on their own, and only then discuss the problems with one another to clarify difficulties they may have had. If the collaboration is done properly then, even though students have worked together, the details of their solutions should still be quite different.

EXAMS AND DESIGN PROJECT

THERE WILL BE SIX (6) EXAMS AND ONE DESIGN PROJECT, which may involve the use of a computer program solver (e.g., Matlab, MathCad, ANSYS). To ensure fairness in your evaluation, the lowest exam score will be dropped.

Exams will be given on Fridays during portion of our section meetings, except during the first week of the term with no exam. Exams are open books and open notes. Each exam will include all (everything) of the materials covered until Tuesday (inclusive) the week of the exam.

Note:

Exams are solved individually without collaboration during our conference times
Additional time might be allowed for preparation and submission of solutions
First exam is on Friday, October 31

Design projects are developed in teams of 3-4 students. Each team will be evaluated based on individual member efforts and on overall team outcomes and collaboration.

GRADING

THE GRADE FOR THE COURSE WILL BE BASED 60% ON THE EXAMS and 40% ON THE DESIGN PROJECT. Participation in course discussions will be taken into consideration.
