Elements of Machine Design
I. Course Prefix/Number: MEC 220
Course Name: Elements of Machine Design
Credits: 3 (3 lecture; 0 lab)
III. Course (Catalog) Description
Course examines design of machine elements as affected by material properties, loading conditions, stresses, deformation and costs. Content includes failure analysis, shafts and couplings, clutches and brakes, mechanical fasteners and springs.
IV. Learning Objectives
The course provides students with the basic background necessary for design of machine elements. Specifically, students will learn how to select the size, geometry and material of machine elements to satisfy the prescribed loading conditions.
V. Academic Integrity and Student Conduct
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.
There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

X. Methods of Evaluating Student Progress
The evaluation process will consist of:
- Three examinations, each 100 points. (75% of grade)
- Eighty-six problems, each 10 points. (25% of grade)
XI. Other Course Information
- Assigned homework is required for the completion of the course.
- Homework must be submitted on the assigned due date. Late homework will not be accepted.
- Solutions must be presented in a clear and orderly manner, with answers boxed in. Homework lacking clarity or written on scrap paper, such as on the back of old memos, etc., will not be graded.
- Ten points of credit will be given for each problem, provided the solution is correct, including all steps used and presented in a clear and orderly manner.
