Professional Engineering Philosophy
& Review Course


The PE exam is one of the last steps towards becoming a professional licensed engineer. Through out these pages you will find my personal engineering philosophy and how I approach engineering technical opportunities. This page will also incrementally grow to provide material for studying for the NCEES PE in mechanical engineering mechanical elements. In addition to the NCEES content, I will also keep adding additional material that a holistic machine design engineer may need through out a diverse career. Product teardowns are being used as a teaching tool for real life engineering questions.

As you start your thought experiment to become a professional engineer (licensed) consider asking yourself: WHY? While I can not attest that the professional engineering license will result in financial gain, I do feel fulfilled knowing that I can legally call myself an engineer. Here is a side note: Even with 4 engineering degrees from MIT I could not legally call myself an engineer. I was legally not allowed to sign a consulting contract to provide engineering services. Starting a company where the title or the description included "engineering" requires a licensed professional engineer. The challenge is that the engineer title is socially often undervalued when it is improperly used. Sometimes people refer to technitians, operators, etc as engineers. Thus, if you want the prestige that comes with the title of engineer reconsider your motivation. In the early 1900's expensive lessons and anomalies were discovered. The first state to pass a law requiring a license to practice engineering was Wyoming in 1907, mainly to restrict untrained individuals from working as engineers and land surveyors. The number one goal for Professional Engineers is to: protect the public health, safety, and welfare. Many states followed suit for their own reasoning.


While licensure is exempt from the code of Hammurabi of Babylon, the professional engineer does take an additional burden of diligence and dedication to the work.
