Course Description: Mechanical engineers are associated with the production and processing of energy and with providing the means of production, the tools of transportation, and the techniques of automation. The skill and knowledge base are extensive. Among the disciplinary bases are mechanics of solids and fluids, mass and momentum transport, manufacturing processes, and electrical and information theory. Mechanical engineering design involves all the disciplines of mechanical engineering. Therefore, this course aims to equip the mechanical engineering students with the fundamentals of these design activities and give them necessary skills to prepare complete, concise, and accurate calculation steps for machine elements. While the first part of the machine elements covering general stress analysis, failure conditions, shaft, spring, permanent and nonpermanent joints design, second part covers rolling contact and journal bearings, gears, clutches, flywheels, flexible machine element design and analysis tools.

Course Objective: The aim of this course is to introduce students the concepts and the use of machine elements in the design and manufacturing field.  The students acquaint with the knowledge and skills in understanding failure modes, better design criterion for machine elements and the capability to design elements like screws, rivets, welded joints, shafts, springs. The students can also develop an understanding of analysis tools of these parts.

Course Material: Text book is listed at the last paragraph.  Besides, lecture notes will be posted on the course web site (possibly after the lecture hour) as pdf files.  These files will include PowerPoint slides presented in the class.  It is strictly recommended that the students review the topics by working on these pdf files given for student’s benefit.  Moreover, there will be some homework sets to be graded, which includes the topics covered in the lecture hours. In addition to the textbook there will be different manufacturers catalogues and information related to the machine elements that are to be presented and discussed in class.

Examinations: There will be 2 mid-term examinations, 1 final examination.  These exams aim to evaluate the machine elements I knowledge of the student,

Attendance: According to the university regulations, students must attend at least 70 % of the lecture hours.  Otherwise, the student gets NA (Not attended) from the course.  Valid excuses are exempt from computation of these percentages.

Apart from the university regulations, it is of student’s benefit to attend all of the lecture hours.  In fact, the students are expected to attend all of the sessions throughout the semester, since the sessions follow a series of applications.

Grading: Final grade will be over 100 points and 5 points extra. Weight of each grading item will be as below.

All the announcements, including the examination dates will be posted on the Moodle web site.
