Course Objectives
To develop an understanding of the relationship between external loads applied to a
deformable body and the internal s
tress, strain and de
formation induced in the body.
To show proficiency in mathematics and basic sciences required to solve structural
engineering and mechanics problem.
To develop analytical and graphical problem solving skills.
Course Outcomes
:
Upon su
ccessful completion of the course, students will be able to
C
alculate and understand the
concepts of stress and strain.
C
alculate, describe, and estimate external loadings, including axial load, shear force,
bending, and torsion, and the resulting deformat
ions and internal stresses associated
with these external loadings.
C
alculate and describe the internal stresses and deformations that result i
n combined
loading conditions.
C
alculate internal stresses and strains through the application of stress transfor
matio
n
equations and Mohr’s circle.
Design components to meet desired needs in terms
of strength and deformation.
Class/Laboratory Schedule

Policies of running the course during the term
:
Lectures will be given in power point presentations. Lecture
notes w
ill be available on the
web
with enough material to cover the topics that will be given during that week. At the end
of the week the lectures will be removed and substituted for other three new lectures and so
on
.
Students are strongly advised to v
isit the web page and have these lectures available with
them in class
.
Remarks
1.
Homework assignments/solutions are distributed and collected every Week. It is
expected that each student will exert enough effort to prepare his assignment
independentl
y and submit the solutions in suitable Engineering Format with a cover

page that include adequate details about the assignment.
2.
It is essential that students read text

book covered material regularly and solve as
many problems from text book as possible a
nd to seek faculty assistance as need
arise.
3.
All submitted home
works must represent the students’ own, and individual, effort.
Plagiarism will not be tolerated, as per KFUPM policies.
4.
The University regulations regarding excessive absences will be stric
tly adhered to in
this course. See the Undergraduate Bulletin for details.
