Coverage of US and SI units where appropriate. 

Here is the best way to practice for the mechanical PE exam. The Mechanical PE Sample Examination simulates the 8-hour test, with 40 problems for the morning (breadth) session and 40 problems each for the 3 afternoon (depth) sessions: HVAC and Refrigeration, Mechanical Systems and Materials, and Thermal and Fluids Systems. The problems use the same multiple-choice format as the exam and are accompanied by full solutions.

The most realistic practice you can get

• 40 problems covering the morning portion of the exam
• 40 problems covering the three afternoon sessions of the exam
• Replicates the exam format, level of difficulty, time limit, and number of problems
• Step-by-step solutions help you check your problem-solving methods
• Helps you identify topics that require extra review
