Unformatted text preview: A&AE 204 Aeromechanics II Spring 2011, MWF 3:30 a.m., MSEE B012 Dr. P.K. Imbrie, ARMS 1300/Civil G293, 496.7225, imbrie@purdue.edu COURSE OBJECTIVES: Develop basic concepts needed to design aerospace structural components that resist “failure.” Principles of static equilibrium and strength of materials are emphasized. 1. Equilibrium Determine reactive and resultant internal forces caused by applied structural loads. 2. Strength of Materials Determine distribution of internal forces on a point by point basis (stresses) and establish the corresponding deformations (strains) caused by structural loads. TEXT: J. M. Gere and B. J. Goodno, “Mechanics of Materials,” 7th edition, 2009, Cengage Learning (required). Additional class notes will be posted on class web page as needed. Suggested Reading: Structures or Why Things Don’t Fall Down, by J. E. Gordon, Da Capo Press, 1978. GRADING: Final course grade will be based on the following factors: Homework Exam 1 Exam 2 Exam 3 Compressive Final Exam 20% 20% 20% 20% 20% 90% ≤ A ≤ 100% 80 % ≤ B < 90% 70% ≤ C < 80% 60% ≤ D < 70% F < 70% OTHER POINTS TO NOTE: 1. Generally, there will be weekly homework assignments. 1. Homework is due at beginning of class on day for which assigned. No late homework will be accepted without prior arrangement with instructor. Late homework’s are reduced 10% per day they are late until one week after the assignment was originally due at which time it is no longer acceptable. You are encouraged to work together and discuss homework problems, but make sure that the work you turn in is your own as you will be required to work alone on the tests. 2. Instructor reserves the right to raise the final grade of any student by one letter. 3. In the event of a major campus emergency, course requirements, deadlines and grading percentages are subject to changes that may be necessitated by a revised semester calendar or other circumstances. Please contact the instructor and/or course webpage for information about changes to this course. 4. The instructor encourages all students to feel free to discuss class related problems with him, and rather than limit students to specified office hours, will maintain an open door 1 5. 6. 7. 8. policy as long as practical. Students are encouraged, however, to make appointments in order to ensure instructor availability. TA office hours will be announced in class. Final examination date and location is scheduled by the University and will be announced in class. Per Purdue policy, students scheduled for more than two examinations in one calendar day are entitled to reschedule any examinations in excess of two. Students who wish to reschedule their AAE 204 examination must inform course instructor of this desire by the end of the 14th week of classes. Please study the attached statement of “Classroom Ethics,” and abide by its principles. The plus/minus grading system will not be used for AAE 204 this semester. Notes, grades, etc. will be posted on class webpage: http://www.itap.purdue.edu/tlt/blackboard/ COURSE OUTLINE: 1. Handout Chapter 1: Review forces, moments, and equivalent force systems 2.

The following guidelines are adopted from a statement of faculty ethics prepared by the AAUP. You are asked to join me in upholding these high standards this semester. Specifically, our ethical obligations are to: 1) Engage in the free pursuit of learning by: • Seeking help and clarification when needed. • Respecting fellow students’, professors’, and guests’ opinions without disparaging and dismissing them. • Seeing beyond “personality issues” with others to appreciate their contributions to the learning environment. 2) Model ethical scholarly standards by: • Avoiding plagiarizing and all other breaches of academic honesty. • Avoiding any seeming approval, acceptance, or encouragement of fellow students’ academic dishonesty and bringing any such instances to the attention of the professor and/or university officials. • Engaging in discussions with other students and professors about ethical issues in academics. 3) Acknowledge, accept, and expect just assessment of your learning by: • Understanding the professor’s methods and rationale for your assessment and asking for clarification if you don’t understand. • Engaging in accurate, just, objective self‐assessments of your own work. • Engaging in constructive, value‐neutral discussion with the professor about discrepancies between your self‐assessment and the professor’s assessment of your work. • Refraining from comparing assessments and grades with classmates’ so as not to diminish classmates’ self‐esteem. 4) Avoid harassment, discrimination, and exploitation by: • Getting to know classmates and the professor as individuals rather than applying prejudices and stereotypes. • Contributing your full effort in team and collaborative projects. • Respectfully voicing your expectations of full participation in team and collaborative projects to fellow students. • Not discouraging, in any way, a member’s full participation in a collaborative project. • Being careful not to make racist, sexist, and other types of discriminatory remarks during class. • Being careful not to monopolize class discussion time so that others do not have a chance to participate or are intimidated about participating. * Reference: The Teaching Professor, Vol. 10, No. 1, January 1996. Modified from 1987 American Association of University Professors guidelines for faculty.
