CATALOG DESCRIPTION
MENG 231 ENGINEERING MECHANICS (3, 1) 3
PART-I: STATICS: Review of Vector Algebra; Principles of Mechanics; Free-Body
Diagrams; Static Equilibrium of Particles and Rigid Bodies; Distributed Force Systems.
Structures, Beams, Trusses, Frames, and Cables; Friction; Center of Mass, Centroid,
and Moment of Inertia.
PART-II: DYNAMICS: Review of Particle Dynamics; Free-Body Diagrams; Force,
Energy and Momentum Methods; Planar Kinematics and Kinetics of Rigid Bodies;
Energy Methods; Vibration Problems.
(PREREQUISITES: MATH 151, PHYS 101)
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-NotesOnly Exams’ that you may have. Having a book, however, provides several additional
advantages.
REFERENCES:
1) Engineering Mechanics-Dynamics by B. FOWLER, SI Ed., Addison- Wesley
2) Engineering Mechanics-Statics by B. FOWLER, SI Ed., Addison-Wesley
3) Engineering Mechanics, Statics and Dynamics, 5TH. ED., E.W. NELSON, Schaum’s
Outlines.
TEACHING TECHNIQUES:
Over-head projector and chalk-and-board (Dry-Marker) will both be used in classroom
presentations. For some sections of the course, Power Point presentations will also be utilized.
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 A4 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.

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;
TO PROVIDE THE STUDENT WITH A THOROUGH UNDERSTANDING OF THE

ABSOLUTELY ESSENTIAL WHEN SOLVING PROBLEMS IN MECHANICS.)
TO PROVIDE A MEANS FOR DEVELOPING THE STUDENT’S ABILITY TO FORMULATE
EQUILIBRIUM EQUATIONS;
TO PROVIDE THE STUDENT WITH GOOD PROBLEM SOLVING SKILLS;
TO PROVIDE THE STUDENT WITH THE FUNDAMENTAL CONCEPTS AND METHODS
OF STATICS AND DYNAMICS;
TO ENHANCE STUDENT’S CREATIVITY AND IMAGINATION AS WELL AS
KNOWLEDGE AND SYSTEMATIC THINKING CAPABILITIES AS REQUIRED BY THE
ENGINEERING DISCIPLINE.
TO PROVIDE THE STUDENT WITH SIMPLE DESIGN AND SAFETY IDEAS.

DETERMINE
THE
RESULTANT

FORCE
SYSTEMS;
INCLUDING
MOMENTS/COUPLES, REACTIONS, AND INTERNAL LOADS.
DEVELOP EQUATIONS OF EQUILIBRIUM AND EQUATIONS OF MOTION, AND SOLVE
THESE FOR FORCES AND/OR DIFFERENT MOTION PARAMETERS, SUCH AS

GRADING AND EVALUATION:
Class-Notes & Participation:
Homeworks and Assignments:
Quizzes:
Midterm(s):
Final Exam:
4%,
10 %,
20 %,
30 %,
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.
