Course Description:
Statics is the branch of engineering mechanics that studies the effects of forces and moments acting on
rigid bodies that are either at rest or moving with constant velocity along a straight path.
Course Objectives:
This course is furnished to provide civil engineering students with the basic skills in engineering
mechanics. Such skills are considered as pre-requisites for many other courses in the civil engineering
curriculum. Among the main concepts that are covered in this course are vectors, equilibrium of a
particle, equilibrium of rigid bodies, trusses and frames, shear and moment diagrams, centroids, and
moment of inertia.
Student Performance Evaluation / Grading
The course consists of a three-hour lecture per week. Homework will be assigned each week.
Explanations or solutions will be given in a separate helping session. Students are expected to do the
homework and submit it weekly on time. Late submission will not be accepted.
Class participation, quizzes and the final examination will evaluate student progress.
Participation:
Active participation in this course by all students is expected. Attendance for all lectures is strongly
advised. Any student whose performance/attendance is unsatisfactory or not up to date will be notified
by the College and may be dropped from the course for insufficient progress or participation.
Exams and Grading Policy:
Homework, Quizzes and Class Participation
10 points
Midterm Exam
30 points
Final Exam
60 points
Total
100 Points
