Strength of Materials

I.     Course Prefix/Number: ENG 217

       Course Name: Strength of Materials

       Credits: 3 (3 lecture; 0 lab)

II.    Prerequisite

ENG 211 (statics).

III.   Course (Catalog) Description

Course covers principles of strength. Content includes stress and strain; torsion, shear and bending moments diagrams; deflection of beams; combined loading; welded, bolted and riveted connections; and columns.

IV.   Learning Objectives

Demonstrate the ability and skills to analyze and interpret stress, strain, deformation, deflection, and loading in a variety of materials and conditions resulting in the following outcomes:

  1. Compute the stress, strain and deformation in a member carrying axial tensile or compressive loads.
  2. Compute direct shear stress.
  3. Compute bending stresses.
  4.  Compute torsional shear stress and deformation.
  5. Compute the stress due to loading in beams.
  6. Consider stress concentrations in stress analysis.
  7. Compute shear stress in beams.
  8. Compute the deflection of beams due to a variety of loading and support.
  9. Compute resultant stresses due to axial, shear, and bending effects.
  10. Evaluate stresses using Mohr’s circle.

V.    Academic Integrity and Student Conduct

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at

VI.   Sequence of Topics

See for outline and supplementary materials.

VII.  Methods of Instruction

The instructor will lecture on concepts and then solve related problems (with the student’s participation).  The instructor will then ask students to solve an occasional problem in class.  In certain cases, the instructor will use visual aides to demonstrate an application.  Some group work will be expected.

Most homework sets include “Fundamental Problems” for practice. These problems have partial solutions in the back of the book. Hints have been enabled within the homework system so that progressive feedback is given to you after each incorrect attempt. Most homework assignments allow up to 6 attempts. There is a 10% late penalty per day past the due date with a minimum of 50% credit.

It is in YOUR best interest to use these resources to master the concepts and be able to solve typical problems. The system is set-up so that student homework comments/questions entered within the homework system are sent directly to my email. You also have the option of emailing me your questions directly at any time.

We also have face-to-face tutoring available. Sometimes, it takes a week after the semester begins for the schedule to be posted.

See for periodic updates to Des Plaines and Skokie schedules. Call the tutoring phone number if there are any questions.

Course may be taught as face-to-face, hybrid or online course.

VIII. Course Practices Required

Read assigned sections of chapters, paying particular attention to example problems within each section.  Depending on your comprehension of the reading, I advise you to look at additional problems and video solutions to help clear up muddy points.

As you are looking at a solved problem, resist the temptation to look at (or hear) the solution before YOU have thought critically about and attempted the problem. Remember, during exam situations you will not have any of these aids available. Just you, your calculator and one side of an 8.5x11 piece of paper as a “formula sheet” (notice, I did not use the word “cheat”).

YOU ARE REQUIRED to have a notebook dedicated to this class in which you number each section and problem, restate the problem and show all the steps to solve the problem (and box in the answer). When using online materials it is tempting to work off the screen using only scratch sheets that are of no use when it comes time to review for an exam. If you go to the tutor, send me work electronically or make email arrangements to meet with me, an organized notebook WILL BE EXPECTED.

When you take exams in-class, you will drop off your notebook with me so I can grade it. It counts as an assignment. Students also have the option of making a short video of their notebook work. Cell phone video as you turn pages is OK (you can get two pages in at a time if you hold the phone long way across). I will set-up a dropbox on d2l for these files.

IX.   Instructional Materials

Note: Current textbook information for each course and section is available on Oakton's Schedule of Classes.

Mechanics of Materials by R.C. Hibbeler, 10th Edition, Pearson/Prentice-Hall.

X.    Methods of Evaluating Student Progress

Achievement of course objectives by the students is determined from the submitted homework and the three exams.  Overall grade will be comprised of:

  1. Three examinations will account for 70% of the grade.
  2. Weekly homework will account for 30% of the grade.

XI.   Other Course Information

Consider engaging in opportunities to explore STEM careers, and build experiences in STEM. Information is available online at Contact Gloria Liu (, 847-635-1738) for more information.

If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center at the Des Plaines or Skokie campus. All students are expected to fulfill essential course requirements. The College will not waive any essential skill or requirement of a course or degree program.

Oakton Community College is committed to maintaining a campus environment emphasizing the dignity and worth of all members of the community, and complies with all federal and state Title IX requirements.

Electronic video and/or audio recording is not permitted during class unless the student obtains written permission from the instructor. In cases where recordings are allowed, such content is restricted to personal use only. Any distribution of such recordings is strictly prohibited. Personal use is defined as use by an individual student for the purpose of studying or completing course assignments.

For students who have been approved for audio and/or video recording of lectures and other classroom activities as a reasonable accommodation by Oakton’s Access Disabilities Resource Center (ADRC), applicable federal law requires instructors to permit those recordings. Such recordings are also limited to personal use. Any distribution of such recordings is strictly prohibited.

Violation of this policy will result in disciplinary action through the Code of Student Conduct.
