The course is intended to introduce students to a variety of mechanical components and their implementation in system design.  Students will learn fundamental concepts, descriptions, terminology, force analysis, methods of analysis and design.  The emphasis in treating the machine components is on methods and procedures that give the student competence in applying these methods and procedures to mechanical components in general.  The students will learn to use the best available scientific understanding together with empirical information, good judgment, and often a degree of ingenuity, in order to produce the best product for today’s society.  The technical considerations are largely centered around stress-strain-strength relations and surface phenomena.  The students will be able to dissect a complex mechanical system and apply engineering skills to perform analysis and design.  Students will use computer software like Solid Edge for graphical convenience of some design problems, and MATHEMATICA/MATLAB/WORKING MODEL to solve computationally intensive problems.

Makeup Work  Makeup for hour exams will be given only for valid University excused absences. Makeup quizzes will not be given. Instead, excused absence on quiz days will be treated as if no quiz were given. Any work missed due to an unexcused absence will receive a grade of Zero. If an hour exam is missed due to valid excuse you must contact me by email within 48 hours after the start time of the missed exam to make arrangements for makeup. For the purposes of this class, a University Excuse must be issued by Engineering Student Services in Shelby.

Accessibility  It is the policy of Auburn University to provide accessibility to it’s programs and activities, and reasonable accommodation for persons defined as having a disability under Section 504 of the Rehabilitation Act of 1973, as amended, and the Americans with Disabilities Act of 1990. Students who have a documented disability and need special accommodations should make an appointment to see me as soon as possible.

Contingency  If normal class and/or lab activities are disrupted due to illness, emergency, or crisis situation (such as an H1N1 flu outbreak), the syllabus and other course plans and assignments may be modified to allow completion of the course. If this occurs, an addendum to your syllabus and/or course assignments will replace the original materials.
