Mechanics of Materials
The Study of Stress, Strain, Torsion & Bending
What is Mechanics of Materials?
Mechanics of Materials is the class that follows Statics. It uses many of the concepts learned in Statics like equilibrium, moments, method of sections, and free body diagrams. The difference between the two courses is that in Statics you study the external loadings. In Mechanics of Materials, we'll study how external loadings affect bodies internally.
We'll look at things like shear stress and strain, how temperature causes deformation, torsion (twisting), bending and more. Gone are the days of rigid bodies that don't change shape. Now things will be getting longer / shorter, twisting, bending and changing shape with temperature changes.
This is a fundamental engineering course that is a must have for any engineering student!

Teaching is my passion. As a University professor I have taught 1000's of students and watched them transform from freshmen into successful engineers. Unlike many STEM professors, I believe in teaching complex material in simple, easy-to-understand terms. I teach my courses in a way I wish I had been taught: straightforward lectures with plenty of examples on how to apply the theory being learned.
In addition to University experience, I also worked as an engineer for 8 years in industry at a well-known defense company. This experience enables me to focus in on topics that are actually applicable in the real world, not just textbook problems.

Who should enroll in this course?
- Engineering students wanting to get a head start on an upcoming Mechanics of Materials course
- Students currently taking Mechanics of Materials who need extra examples and explanations
- Students and professionals who are preparing to take the Fundamentals of Engineering Exam
What do I need to know before starting?
The typical prerequisites for this class are Statics and Calculus. We will be using a few derivatives and integrals so you should be familiar with those concepts. We will cover everything else you need.
Is there a recommended textbook?
I, along with most students I've taught, really like the Mechanics of Materials text by Hibbeler. If you don't already have a textbook this one would be a great resource, although it is not required for this course.
Why wait? There's no better time than now! Enroll today!
