There are several other texts on Strength of Materials and Mechanics of Materials available around TA405 - TA407 in Wendt Library. You should also keep your Statics text handy for reference.

Course Format: This course meets for three lecture hours per week. Lectures will contain discussion of basic concepts, applications, and examples on topics covered. Hour exams will be conducted in the evenings.

Course Description: This course is intended for sophomore level engineering students who have completed EMA 201 and

Math 222. Mechanics of Materials will give the student the opportunity to learn about the basic tools for stress, strain and

strength analysis. By the end of the course, methods for determining the stresses, strains and deflections produced by applied loads will be understood. This course is a foundation to many advanced techniques which allow engineers to design structures, predict failures and understand the physical properties of materials.

Course Content: The following general topic areas will be covered in this course.

Estimated Workload: Successful completion of this course will require the student to participate in the following activities actively and regularly: complete assigned readings, attend lectures, submit homework and design problems when they are due, and pass all exams. Lectures will cover general topics, but lectures and reading material are meant to complement each other rather than repeat each other. Thus, attendance is critical and you are responsible for all topics covered in the syllabus.

This is a 3 credit course with 3 hours of scheduled class time per week (additionally EMA 304 contains 6 laboratory sessions). It is expected that you will have to spend a minimum of 6 additional hours per week on course reading, assignments and studying outside of class. The exact amount of time spent by a student on the items mentioned above will vary depending on the background, preparation, and learning style of the individual.

Conduct: The instructor and the University of Wisconsin expect the highest standards of honesty and integrity in the academic performance of its students. Any student caught cheating in this course will receive an F and the case will be reported to the Dean

of Students.

In light of this, it is important to understand the allowable level of collaboration in this class. Students are encouraged to discuss home work and course material with the instructor and classmates. However, the submitted homework solutions and exams must involve only the individual student's effort. For group design projects, each individual's contribution will be identified on the assignment.

Participation and Attendance: This course will be taught with a mixture of lecture and student participation. Class participation and attendance are expected of all students. This class is a safe place for you to test out your ideas and ask questions. The discussions we have in class will be more valuable to you and your classmates if you come prepared. Read the sections of the textbook being covered in the class prior to class time.

It is expected that the instructor and students will attend classes and arrive to class on time. Attendance of all classes is expected. If you will not be able to make class, please contact the instructor in advance.

E-Mail Distributions List: There is an e-mail distribution list for the class which will be used for announcements and reminders. Please check your e-mail account on a regular basis.

Homework: Each home work problem must be written on a separate piece of paper with the following information:

All homework problems will be collected at the beginning of the each class period. At that time, all assigned problems will be collected although only one problem from each set will be graded. Some credit will also be given for attempting the other problems in the assignment. Homework assignments will be returned at the next lecture period. Solutions to all required problems will be posted outside of 533 ERB. The solutions are not available for photocopying.

Design Problems: Engineering design is an important part of every engineering field and design concepts are integrated into the Mechanics of Materials course so that the concepts introduced in this class can be applied to real world problems. The design project will be an open-ended design problem. Both a written report and an oral presentation will be required. A team will be assigned for the group design problem.

Laboratory: EMA 304 ONLY. EMA 304 includes six laboratory demonstrations on basic strength of materials properties of metals. Attendance to all six laboratories is mandatory and no make-up labs will be scheduled. All six labs will require or some results or calculations to be prepared and turned in at the end of the lab period for grading. Two complete lab reports will be required and four short quizzes will be conducted in the semester.

Exams: There will be 2 hour exams and one final exam. Hour exams will be conducted in the evening. The hour exams and final exam will be closed book, closed notes, and cumulative. Hour exams will consist of several problems and must be completed in the 50 minute time period. The final exam will be similar to the hour exams in format with twice as many problems. A total of 2 hours is allowed on the final exam.

Homework 25% 15%

Design Problems 25% 25%

Laboratory n/a 10%

Hour Exams 20% 20%

Final Exam 30% 30%

Grading will be referred to the following scale, which you can think of as cutoffs that may be modified based on the overall performance of the class, the interaction between students and instructor, and other factors that may shift or widen the intervals. You can be fairly sure that if your final average is 93%, you will get an A, a 90%, you will get an AB, an 85%, you will get a B, etc. I can only say "fairly sure" to guard against the highly unlikely circumstance in which that everybody in the class is above the cutoff in question. This allows you to perform to the best of your ability without having to directly compete with your classmates for your grade. Under this scheme it is possible for the entire class to get an A or the entire class to get an F depending on the ability and performance of the individuals in the class. It is also easy for you to evaluate how you are doing in the class during the quarter. The following criteria will be used to assign a grade for the course:

100 - 93% A

92 - 90% AB

89 - 85% B

84 - 82% BC

81 - 77% C

76 - 70% D

< 70% F

The instructor has the discretion to raise your score by letter grade at the end of the semester. Grades for EMA 303 and EMA 304 will be considered independently.

Late Policy: No late homework, design reports, or laboratory reports will be accepted. Make up exams will only be allowed in very exceptional circumstances.

Disability Access: If you have a physical or learning disability that the instructor should be aware of, please arrange for an individual consultation with the instructor to discuss accommodation. Disability accommodations are also provided through the McBurney Disability Resource Center, 263-2741.
