EGR 209/210 - SOLID MECHANICS

PADNOS SCHOOL OF ENGINEERING

GRAND VALLEY STATE UNIVERSITY

COURSE OUTLINE

FALL SEMESTER 1996

: There are two objectives for this course. First it is important that you master the content of this course as this is the foundation for engineering analysis as well as almost all of the mechanical engineering courses that follow. Second, it is important that you master the engineering approach to problem solving.

: Dr. Hugh Jack, P.Eng.
: Assistant Professor, School of Engineering
: Office: Suite 618, Eberhard Center

: email: jackh@gvsu.edu

: Regular office hours will be announced in class. Student questions and discussions at other times are welcome on a walk-in or pre-arranged basis.

: Mechanics of Materials, by F.P. Beer and E.R. Johnson
: EGR 209/210 -Statics and Solid Mechanics Lecture Notes, by H. Jack

: for EGR 209 students Physics 230 and Math 202 is required
: for EGR 210 students they need to have taken a statics course equivalent to lectures 1 to 26.

There will be a one hour final exam for EGR209 and 210. For students in EGR 209 there will also be two midterm tests, each one hour in duration. Some points of interest about the exams,

: · All tests will be "Closed Book", but you will need to bring your own scientific calculator.
: · An equation sheet will be permitted for the final examination only.
: · All students will be expected to write tests at the scheduled time, make-up tests will be given only in the most extreme circumstances at the discretion of the instructor.

You will not be able to learn this material if you do not do problems. To encourage you to do homework in a professional manner, random samples of the assignments will be collected and graded. This homework may be collected as soon as the next class after introduction, and when collected it is due immediately. All homework solutions should be logical, concise, clear, and readable.In general the following rules should be observed,

: · Do all work on engineering computation paper.
: · Multiple page solutions should be stapled and given page numbers.
: · At the top of the page indicate your name, the date the work was done, and the course number.
: · Each problem should begin with a brief problem statement (try to avoid copying out the question).
: · Free body diagrams will be required for most solutions, and should appear near the start.
: · The problem solution should be concise, logical, clear, neat, and correct.
: · The final answer should be clearly indicated with a box, or leader lines.
: · All solutions should be done in pen. If you make a mistake, cross it out once.

The grade for this course will be determined as follows:

: Exam(s) 75%
: Homework 25%
: Study Group Adjustment 0-5%

The use of study groups is an excellent learning and support mechanism. In this course, forming a study group can also directly impact your grade.

After the examination, the average exam grade for the members of a study group will be calculated. The "study group adjustment" will then be made on each group members grade. The amount of that adjustment will be determined using a linear method with an average group grade of C (2.0) receiving an upward adjustment of 1% and an average group grade of A- (3.7) or better receiving an upward adjustment of 5%.

The criteria for study groups is as follows,

: 1) Study groups are voluntary; no one is required to join a study group.
: 2) Study groups shall be composed of four, five, or six students.
: 3) Study groups must be formed and registered with the instructor not less than one week prior to an exam.
: 4) Groups may expel or add a member by unanimous vote.
: 5) If a group membership falls below four, the group is automatically disbanded unless the members of the group vote in a replacement.
: 6) No student may belong to more than one group.
