TEXTBOOK:
We will follow, Hibbeler’s “Engineering Mechanics-Statics and Dynamics, 10th. Ed., Prentice-Hall” as a textbook. Taking notes in class will be helpful for the ‘Open-Notes-Only Exams’ that you may have. Having a book, however, provides several additional advantages.
REFERENCES:
1) Engineering Mechanics-Dynamics by B. FOWLER, 3rd. Ed., Addison- Wesley, 2002
2) Vector Mechanics for Engineers-Statics and Dynamics, 6th. Ed., F.P. Beer and E.R. Russel, McGraw-Hill, 1999.
3) Engineering Mechanics, Statics and Dynamics, 5TH. ED., E.W. NELSON, Schaum’s Outlines.
TEACHING TECHNIQUES:
PowerPoint presentations, over-head projector and chalk-and-board (Dry-Marker) will both be used in classroom presentations. Tutorials will be organized to establish a closer contact with students and help enhance their problem solving capabilities.
MINIMUM STUDENT MATERIAL:
Assigned Textbook, a scientific calculator, binder for handouts and class notes, sufficient amount of A-4 size plain papers or a notebook dedicated to this course only, and three pens/pencils of different colours. The Class-Notes Binder will be collected together with your Final Exam and shall be graded. You may take the binder back after it is graded.
COURSE OBJECTIVES:
THE MAIN PURPOSE OF THIS COURSE IS
1. TO PROVIDE THE STUDENT WITH A CLEAR AND THOROUGH UNDERSTANDING OF THE THEORY AND APPLICATIONS OF ENGINEERING MECHANICS, COVERING BOTH STATICS AND DYNAMICS; AND IN THIS CONTEXT;
2. TO PROVIDE THE STUDENT WITH A THOROUGH UNDERSTANDING OF THE CONCEPT, DRAWING, AND THE USE OF FREE-BODY DIAGRAMS (WHICH IS ABSOLUTELY ESSENTIAL WHEN SOLVING PROBLEMS IN MECHANICS.)
3. TO PROVIDE A MEANS FOR DEVELOPING THE STUDENT’S ABILITY TO FORMULATE EQUILIBRIUM EQUATIONS;
4. TO PROVIDE THE STUDENT WITH GOOD PROBLEM SOLVING SKILLS;
5. TO PROVIDE THE STUDENT WITH THE FUNDAMENTAL CONCEPTS AND METHODS OF STATICS AND DYNAMICS;
6. TO ENHANCE STUDENT’S CREATIVITY AND IMAGINATION AS WELL AS KNOWLEDGE AND SYSTEMATIC THINKING CAPABILITIES AS REQUIRED BY THE ENGINEERING DISCIPLINE.
7. TO PROVIDE THE STUDENT WITH SIMPLE DESIGN AND SAFETY IDEAS.
COURSE OUTCOMES:
THE STUDENT TAKING THIS COURSE WILL BE ABLE TO
1. UNDERSTAND THE BASIC PRINCIPLES OF MECHANICS AND TO APPLY THEM TO REAL-LIFE PROBLEMS OR TO NEW SITUATIONS.
2. DRAW FREE-BODY DIAGRAMS
3. FORMULATE AND USE THE EQUILIBRIUM EQUATIONS
4. IDENTIFY THE PRINCIPLES AND EQUATIONS THAT APPLY, AND USE THEM IN SOLVING STATIC AND DYNAMIC PROBLEMS.
5. USE THE MATHEMATICAL TOOLS AND THE STANDARD PROCEDURES AS WELL AS PERFORMING NUMERICAL CALCULATIONS.
6. ANALYZE ONE, TWO AND SOME THREE DIMENTIONAL FORCE SYSTEMS AND TO DETERMINE THE RESULTANT OF FORCE SYSTEMS; INCLUDING MOMENTS/COUPLES, REACTIONS, AND INTERNAL LOADS.
7. DEVELOP EQUATIONS OF EQUILIBRIUM AND EQUATIONS OF MOTION, AND SOLVE THESE FOR FORCES AND/OR DIFFERENT MOTION PARAMETERS, SUCH AS DISPLACEMENT, VELOCITY, AND ACCELERATION OF PARTICLES, RIGID BODIES, AND SIMPLE MECHANICAL SYSTEMS.
GRADING AND EVALUATION:
Class-Notes & Participation: 4%,
Homeworks and Assignments: 10 %,
Quizzes: 20 %,
Midterm(s): 30 %,
Final Exam: 36 %.
ATTENDANCE:
Attendance to lectures and tutorials are essential and expected. Attendance shall be taken. You must be there to participate. If you miss more than one midterm/monthly exams and/or quizes or if your attendance record is less than 75 %, your condition may be treated as “Non-Gradable” and shall receive an “NG” grade.
PLAGIARISM
This is intentionally failing to give credit to sources used in writing regardless of whether they are published or unpublished. Plagiarism (which also includes any kind of cheating in exams) is a disciplinary offence and will be dealt with accordingly.
