Mechanics of Materials, 6th edition By William F. Riley, Leroy D. Sturges and Don H. Morris. Publisher: John Wiley & Sons, INC. ISBN: 0-471-70511-X

Objectives: The main purpose of the course is to learn the fundamentals of mechanics of materials, including stress, strain, stress-strain relationships, stress concentration, stress transformation equations and Mohr's circle for plane stress analysis, analysis of plain stresses and strains. Teaching Mode:

In the scheduled lectures, theory and sample problem solutions will be presented. Additional material will be supplied on hand-out sheets, where necessary. The laboratory period is for the solution of problems as assigned. Some experiments may be conducted. Attendance is mandatory. There will be two types of assignments. Lab assignments will be given at the start of each lab and will be handed in at the end of each lab. Take-home assignments are due a week after they have been given and should be handed in during the laboratories. Completed assignments are necessary to fulfil the

requirement of the course.

Mid-Term Test:

Closed book and notes; 3 hrs; to be held on October 23, 2009 from 12:00 15:00. Formulae provided.

Final Exam:

During the official exam period; closed book and notes; 3 hrs; formulae provided.

Notes: 1- Should a student miss a mid-term test or equivalent (e.g. studio or presentation), with appropriate documentation, a make-up will be scheduled as soon as possible in the same semester. Make-ups should cover the same material as the original assessment but need not be of an identical format. Only if it is not possible to schedule such a make-up may the weight of the missed work be placed on the final exam, or another single assessment. This may not cause that exam or assessment to be worth more than 70% of the student’s final grade. If a student misses a scheduled make-up test or exam, the grade may be distributed over other course assessments even if that makes the grade on the final exam worth more than 70% of the final grade in the course. 2- Students who miss a final exam for a verifiable reason and who cannot be given a make-up exam prior to the submission of final course grades, must be given a grade of INC (as outlined in the Grading Promotion and Academic Standing Policy) and a make-up exam (normally within 2 weeks of the beginning of the next semester) that carries the same weight and measures the same knowledge, must be scheduled. 3- Medical or Compassionate documents for the missing of an exam must be submitted within 3 working days of the exam. Students are responsible for notifying the instructor that they will be missing an exam as soon as possible. 4- Requests for accommodation of specific religious or spiritual observance must be presented to the instructor no later than two weeks prior to the conflict in question (in the case of final examinations within two weeks of the release of the examination schedule). In extenuating circumstances this deadline may be extended. If the dates are not known well in advance because they are linked to other conditions, requests should be submitted

2

as soon as possible in advance of the required observance. Given that timely requests will prevent difficulties with arranging constructive accommodations, students are strongly encouraged to notify the instructor of an observance accommodation issue within the first two weeks of classes. 5- The results of the first test of mid-term test will be returned to students before the dead line to drop an undergraduate course in good Academic Standing. 6- All of the required course-specific written reports will be assessed not only on their technical/academic merit, but also on the communication skills exhibited through these reports. 7- Students are required to adhere to all relevant University policies including the Student Code of Academic Conduct (www.ryerson.ca/senate/policies/pol60.pdf) and Non-Academic Conduct (www.ryerson.ca/senate/policies/pol61.pdf) 8- Students are required to obtain and maintain a Ryerson Matrix e-mail account for timely communications between the instructor and the students. 9- Any changes in the course outline, test dates, marking or evaluation will be discussed in class prior to being implemented.
