Description

Deforms is the following class after statics and it focuses primarily on the study of stress, strain, and deflection for various systems and loadings. Additional topics include stress transformations, buckling, and how to design things using your newfound knowledge.

I find too often that students don’t know why they are learning something or how it relates to future classes or career. Some professors are too focused on getting the material over to you and giving you the test. Sound familiar? I will teach you how to think like an engineer, which means being able to break down complicated problems into simple pieces that you already know how to do! I recognize that students value simplicity and logic over complicated derivations and memorized processes. I will teach you the simplest way that has helped my students become successful for the past 5 years.

By the end of the course, you will know how to approach fundamental problems in each of the major topics and explain why they are relevant in engineering. The course is designed to also be used as a reference when you are taking the full version of the course as well, so don’t be afraid if you don’t pick everything up the first time you see it! My hope is that you have the “ah-ha that’s why Scott approached it that way” moment when you take the real course.

Who this course is for:

  • Sophomores in mechanics-based engineering majors
  • Students who are preparing to take Mechanics of Materials (Deforms)
  • Young professionals who want to brush up on their engineering curriculum
