4. EGR 209 - SOLID MECHANICS Syllabus

There are three 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. Finally, you will be expected to develop critical thinking skills by applying concepts learned in class to mechanical systems.

There will be a final exam. There will also be two midterm tests, each one hour in duration. 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.

Within the first few lectures a project topic will be chosen. The selected mechanical structure will be analyzed over the term as relevant material is covered. Segments of the report will be judged acceptable (100%)/not-acceptable(0%). In the event a portion of the work is not acceptable, there will be a single chance to correct it. As with the work of a Professional Engineer, at any time your work may be reviewed, and the grade changed. The project will be kept up to date by adding to relevant web pages. The work will be done in groups of three students.

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, or on Mathcad.

• 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 (do not copy out the question).

• Free body diagrams will be required for most solutions, and should appear before the calculations.

• The problem solution should be concise, logical, clear, neat, and correct.

• The final answer should be clearly indicated with a box, or leader lines.

• Mathcad solutions should be done entirely within Mathcad (i.e., not with a calculator or scrap paper)

The grade for this course will be determined as follows:
