The Mechanical Engineering Professional Exam

The Mechanical Engineering Professional Exam is broken up into two sections.

There is the morning part which is also known as the breadth exam. This exam is taken by everyone who is taking the PE Exam to get their mechanical engineering license.

The second part is the afternoon exam, which is known as the depth exam. This is a more focused exam geared towards the discipline you have chosen to become licensed in.

There are three disciplines too choose from:

  • HVAC and Refrigeration (1 Hour Sample Exam)
  • Thermal and Fluids Systems
  • Mechanical Systems and Materials

I also wish to mention this sample FE Exam. Feel free to take it and see how well you remember some of the core materials.

Breath Exam

The morning exam can roughly be broken down into the following sections. (According to the NCEES website)

  • 30% – Basic Engineering
  • 20% – Mechanical Systems and Materials
  • 17% – Hydraulics and Fluids
  • 15% – Energy & Power Systems
  • 18% – HVAC & Refrigeration

Each of the above sections can be broken down into further sections that deal with applications and principles.
