Course Description: This course is an important building block in learning how to analyze and design structures and equipment-parts under various applied loads.  Throughout the course, a basic understanding of the principles of force-stress equilibrium and techniques of analyzing stresses and strains of structural members will be acquired.

Objectives:  For sophomore and transfer students,

1. To introduce the basic concept of stress and strain of various material,

2.  To introduce the means to calculate axial, bending, shear, and torsional stresses of simple structural cross-sections,

3.  To introduce the concept of stress transformation using stress transformation equations and Mohr’s circle,

4.  To solve simple structures and draw shear force and bending moment diagrams,

5.  To solve simple indeterminate structures by using strain compatibility,

May 01   Review

May 06            Final Exam                             Ch.1  - Ch.11

Students are responsible for studying the textbook in advance.  This will be checked by unscheduled short quizzes.   The total weight of short quizzes will be worth 15 % of grades.

Attendance:     Attendance is required at all classes.  Absences excused only for valid reasons.

Grade Policy: Based on total max. 600; two exams (200), quizzes (100),  homework (100),  final exam (200).

Homework Policy:  

1. Due on a day shown on the syllabus.  The homework must be submitted before starting a class. 

2. Individual problems will be graded on 0 to 10 scale.

3. No late homework will be accepted.   This way, every student will be treated fairly.

4. Rules in preparing homework:

• Use engineering paper, one side only.

• State the requirement of the problem and solve problems step by step without obscurity.    Answers without proper procedure and calculation will not be accepted.

• Draw all diagrams using straight edges for the problem statements and for the solutions, with an accurate scale.

 Exam Policy:

1. All exam will be a closed book exam.   Students can make and bring in one page summary or equations of the subject course materials to the exam.

2.  Final exam paper will not be returned to the students.

 Special Needs:

If you need course adaptations or accommodations because of a disability, if you have medical and/or safety concerns to share with me, or if you need special arrangements in case the building must be evacuated, please make an appointment with me as soon as possible.”
