Please read this page carefully, as these policies will be followed without exception during the term. This page was posted on September 2, 2005 and will not change until December 31, 2005.
You may collaborate to solve the homeworks, but you should write your own solutions yourself and make sure you understand everything you write down. The projects [2.710 only] are collaborative by nature, but each team member should be at least aware of what other team members are doing (see the projects page for more details). Naturally, no collaboration is allowed in the quizes and final exam.
As you will find out, there will be three kind of homework problems: (a) simple substitution type problems, that you can solve easily once you comprehend which formula applies where; (b) deeper problems that require you to prove some result that was omitted in class, or derive a follow-up result from the lecture; (c) research-grade problems [2.710 only], where the answer is open-ended and may require some extra thinking on your part. Normally, each 2.71 homework will have 2-3 problems of type (a) and 1-2 problems of type (b); each 2.710 homework will have 1-2 problems of type (a) and 2-3 problems of type (b), while problems of type (c) will be rarer (1 every 3-4 homeworks, and in that case there will be no problems of type b). In the weeks leading to the Quiz, we will post solved practice problems and their solutions. These are like traditional assignments, except they do not have to be turned in. Therefore, you should solve them without looking at the solutions, and only after you are satisfied with your own solution should you look at ours.
The instructors will be available to answer questions on the assignments during office hours and by e-mail as late as possible before the due date. Please do not phone-call regarding homework questions. E-mail is much less intrusive.
The instructors dislike negotiations of the type "I have three more homeworks due on that date, can I get an extension?" Please be professional and manage your time so that you can be punctual in this as well as other classes. If you anticipate a major disruption (e.g., religious prohibition from work, a competitive athletic event or a doctoral qualifying oral exam) please arrange at least one week ahead of time with the instructors on how and when to deliver your conflicting assignment. If you deliver a homework late without excuse, 25% of the grade will be subtracted for every overdue date (so your paper will be worthless after the 4th day).
In case of sickness or other personal/family emergencies: if you notify us ahead of time (e-mail or phone-call received before the time the class starts on the date the assignment is due) we will postpone your due date for as long as you need to recover. If you wait until after other homeworks are collected, and the solutions are posted, we may ask you for a letter from the Medical Department or the Counseling Deans in order to give you full credit for the overdue homework. The same policy applies if you miss a Quiz. In case of a missed Quiz with a good justification, we will do everything possible to reschedule the missed Quiz at a mutually convenient time. The standard Institute policies apply if you miss the Final Exam.
We will make every effort to post solutions right after the due date for each homework. If you deliver your homework late, you should refrain from looking at the posted solutions under any circumstances. We count on your honor and conscience that you will abide by that rule.
Even though the Mechanical Engineering department has some grade distribution guidelines in place amounting to "grading on a curve," we will not follow them. According to Institute policies, each grade designation is earned based on the competence that you demonstrate during the course of the subject. Please see Section 2.60 of the Rules and Regulations of the Faculty for more information. In both 2.71/2.710 subjects, we use the Institute definitions.
