Course Description: The course covers the following topics; statics of particles: forces in plane, forces in space, equilibrium, moment of a force, moment of a couple, equivalent systems of forces on rigid bodies, equilibrium in two dimensions, equilibrium in three dimensions, distributed forces: centroids and center of gravity, analysis of structures: trusses, frames and machines, internal forces in beams and cables, friction, moments of inertia of areas, moments of inertia of masses, method of virtual work. 

Course Objectives:

1) To provide definition of force and moment vectors and give necessary vector algebra

2) To explain the concept of equilibrium of particles and rigid bodies in plane and 3D space

3) To give information about support types and to give ability to calculate support reactions

4) To explain the equilibrium of structures and internal forces in trusses, and frames

5) To give information about distributed loads

6) To provide information on moment of inertia

7) To explain virtual work concept.   

Course Material: Text Book is “Engineering Mechanics-Statics, Hibbeler, R.C.13th Edition, Pearson Prentice Hall, 2013, ISBN 978-0-13-291554-0.”

Lecture notes are to be provided via the web site of the course (possibly before the lecture hour) as pdf files. These files will include PowerPoint slides presented in the class. Study sets will be posted on course’s web site at the beginning of each chapter. It is strictly recommended that the students review the topics by working on these study sets given for student’s benefit.

Examinations: There will be 2 mid-term examinations, 1 final examination, and 5 quizzes. 

Assignments: Homework will be assigned 5 times. The students should do the homework, but will not be submitted for evaluation. They are to make the student ready for exams. They will be not be assessed within the overall grade of the student.

Attendance: According to the university regulations, students must attend at least 70 % of the lecture hours. Otherwise, the student gets NA (Not attended) from the course. Valid excuses are exempt from computation of these percentages. 

Apart from the university regulations, it is of student’s benefit to attend all of the lecture hours.. 

Grading: Overall final grade will be over 1050 points. Weight of each grading item will be as below. Quiz question will be from the related homework.

    MT-1 exam grade over 200

    MT-2 exam grade over 250

    Final exam grade over 300

    Quiz grades over 250 (5 x 50)

+ Attendance over 50 (for >70%)

    Final grade over 1050

All the announcements, including the examination dates will be posted on the course web site.
