Prerequisite : Basic college calculus and physics courses
Course Description : This course teaches the fundamental concepts of statics, force systems,
analysis of structures, friction, force systems and area moments of inertia. The course teaches
strength of materials including properties, stress, strain, torsion, shear, load, vectors, resistance and
beam composite strength.
Course Objective
: It is the instructor's intention to provide students in engineering with a
broad, but practical and useful overview of mechanics. Students must be able to understand systems
of forces and be able to draw free-body diagrams, analyze/understand simple solid mechanics
problems, appreciate the range of material response to stress, up to and including failure, explain the
roles played by stress concentrations and flaws in promoting failure.
Course Outcomes : Upon completion of this course, the student will be able to:
11. Compute numeric values for simple

Course Requirements
Attendance
Minimum attendance requirement is 70% by the
university’s regulations. Students are urged to
attend all lecture periods. However, if such a
class is missed, it is the student’s responsibility
to find out what happened in class that day and
to come to the next class prepared to participate
actively. Absence from a quiz or exam will
result in a grade of zero.
Grading
The course grade will be determined as follows:
25% Midterm Exam I
25% Midterm Exam II
15% Homework Assignments
35% Final Exam
100%
Academic Honesty
Academic honesty is expected of all students.
Cheating and plagiarism are violations of
academic honesty. If academic dishonesty is
suspected, a student may receive a failing grade
on an exam or homework. Discussion will occur
before penalties are given. Purposeful
dishonesty may be reported to the University’s
Student Conduct (discipline) Committee.
Cheating occurs when one uses deceitful means
to cheat, e.g. crib notes, copying or imitating the
language and ideas of another, without
referencing, and presenting them as one’s work,
e.g. copied papers, abstracts, sections of books,
etc.
Each student is required to write and sign the
following Honor Pledge on the first page of his or
her exam and homework papers:
“I have neither given nor received any aid, except
those allowed, in this exam (homework)”
