The Principles and Practice of Engineering (PE) - Mechanical: Machine Design and Materials exam is a licensure examination administered by NCEES for engineers seeking professional engineering licensure in the machine design and materials discipline. The exam contains 102 questions delivered in a computer-based format and tests your ability to apply engineering principles to the design, analysis, and evaluation of mechanical components, systems, and the materials used to build them. Content spans six knowledge areas: Basic Engineering Practice, Mechanical Attachments, Mechanical Components and Assemblies, Mechanics of Materials, Power Transmission, and Supportive Knowledge. Candidates are typically practicing engineers with at least four years of qualifying post-graduate work experience who have already passed the Fundamentals of Engineering (FE) exam. The exam emphasizes practical judgment as much as calculation, requiring you to select appropriate materials, size components for real loading conditions, evaluate failure modes, and apply codes and standards correctly. Passing demonstrates that you can independently take responsibility for engineering work affecting public health, safety, and welfare. In return, you gain the legal authority to seal and sign engineering drawings, a credential that expands career opportunities in consulting, manufacturing, product development, and forensic engineering, and the professional standing that comes with licensure.
