Course Objective:

1- To tech the student how to formulate a practical problem and use the engineering tools and engineering sciences to solve it.

2- To illustrate the integration of design principles and materials selection.

3- To illustrate the fundamentals of design concepts.

4- To illustrate the loading conditions and the accompanied stress and strain of different machine elements under working conditions



1- Design Criteria. Theories of Failure Under Static Loading, Fatigue, Deflection, Wear, Buckling , Creep, Impact.                                          

2- Design Factors. Design (safety factor), Stresses Concentration, Residual Stress.

3- Engineering Materials. Mechanical Properties of Materials, Materials Selection.

4- Stress & Strain in Simple Machine Members.

5- Design of Machine Elements: Shafts and Shaft Couplings, Fastenings, Power Screws, Springs, Gears, Belt Drives, Journal and Roller Bearings.

General rules 


·    The student will be considered absent in a class after the teacher finishes taking the students attendance.

·    The student will not be allowed to come into class after 20 minutes pass from the beginning of the class, unless he has a very good excuse.  

·    In case the student is absent three classes without official excuse he will not be permitted to attend the final exam.

·    The student will be considered absent with excuse in case he brings an official excuse from the college administration.

·    There will be two points’ deduction for each absence without permission.

·    The student attendance should be in accordance with the college dress code.


Homework and homework report:

 The homework and homework report should follow the following instructions and rules:

·    The homework report should be written on one face of A4 papers.

·    The homework should be handwritten in pencil and the use of a computer will not be allowed unless otherwise stated.

·    The exercise number and heading should be written before the answer.

·    When writing the answer you should start by writing the formula used firs followed by your answer.

·    The units used should be included in the final answer.

·    The homework should have a cover having all the information needed and the report should be stapled.

·    The homework should be handed in the beginning of the class on the assigned date.

·    The homework that does not follow these rules will not be taken into consideration.


The mid term exams:

·    In case the student misses one of the mid term exams without official excuse (permit), he will not have another exam and his grade in this exam will be null.

·    In case the student misses one of the mid term exams with official excuse, the teacher of the course will take what he sees fit to evaluate the student.

·    In case the student gets a low grade in the mid term exam, he will not have another chance or a make-up exam.

·    The student should bring all the necessary tools needed for the exam (calculator, pencil, ….etc.)
