The PRC Mechanical Engineer Licensure Examination (MELE) requires a general weighted average of at least 70% with no rating below 50% in any subject. It spans three board subjects weighted 30/35/35: Machine Design, Materials and Shop Practice; Industrial and Power Plant Engineering; and Mathematics, Engineering Economics and Basic Engineering Sciences. The exam is governed by RA 8495 and the Philippine Mechanical Engineering Code, administered by the PRC Board of Mechanical Engineering over two days.

1In the Philippine Mechanical Engineer Licensure Examination (MELE), a candidate must obtain a general weighted average of at least what percentage, with no individual subject rating falling below a stated floor?
2The MELE is divided into three board subjects. Which subject carries the 30% weighting?
3A solid circular shaft transmits a torque T. If the shaft diameter is doubled while T is held constant, the maximum torsional shear stress on the surface becomes what fraction of the original stress?
4In an ideal Rankine cycle, which process occurs in the boiler?
5The coefficient of performance (COP) of a refrigerator operating on a reversed Carnot cycle between a cold reservoir at TL and a hot reservoir at TH is given by which expression?
6Under the Philippine Mechanical Engineering Code, a high-pressure boiler is one that furnishes steam at a gauge pressure in excess of which value?
7For a belt drive, the ratio of tight-side tension T1 to slack-side tension T2 (neglecting centrifugal effects) is governed by which relationship, where f is the coefficient of friction and theta is the angle of wrap?
8A car accelerates uniformly from rest to 20 m/s in 8 seconds. What distance does it travel during this interval?
9In a four-stroke spark-ignition engine, how many crankshaft revolutions are required to complete one full thermodynamic cycle in a single cylinder?
10For a square key of width W and length L transmitting torque between a shaft and hub, which two failure modes are checked in standard key design?
About the PRC Mechanical Engineer Exam
The PRC Mechanical Engineer Licensure Examination (MELE) is the objective written board examination required to register as a Mechanical Engineer in the Philippines under Republic Act No. 8495 (the Philippine Mechanical Engineering Act of 1998). It is administered by the Professional Regulation Commission and its Board of Mechanical Engineering over a two-day schedule, covering three board subjects: Machine Design, Materials and Shop Practice (30%); Industrial and Power Plant Engineering (35%); and Mathematics, Engineering Economics and Basic Engineering Sciences (35%). The separate Professional Mechanical Engineer upgrade is interview- and report-based and is not part of this examination.

Frequently Asked Questions
What is the passing rule for the PRC Mechanical Engineer board exam?
Under RA 8495 and its implementing rules, a candidate must obtain a general weighted average of at least 70% across all subjects, with no rating below 50% in any individual subject. A rating below 50% in even one subject is disqualifying regardless of the overall average.
What subjects are covered in the MELE?
The examination has three board subjects: Machine Design, Materials and Shop Practice (30%); Industrial and Power Plant Engineering (35%); and Mathematics, Engineering Economics and Basic Engineering Sciences (35%). Together they cover machine elements, power plants, refrigeration, thermodynamics, fluid mechanics, mathematics, engineering economics, and mechanical engineering law and ethics.
Is the Mechanical Engineer exam the same as the Professional Mechanical Engineer credential?
No. The Mechanical Engineer (ME) tier is the objective written licensure examination covered here. The higher Professional Mechanical Engineer (PME) tier is an upgrade based on an interview and a technical report, not a multiple-choice written exam, and is not part of this practice set.
What law governs mechanical engineering practice in the Philippines?
Republic Act No. 8495, the Philippine Mechanical Engineering Act of 1998, regulates the practice of mechanical engineering. It establishes the Board of Mechanical Engineering, the licensure examination, registration requirements, and the scope of practice. The Philippine Mechanical Engineering Code (PME Code) governs the design and operation of mechanical equipment such as boilers, pressure vessels, and refrigeration systems.
How is the exam administered?
The Professional Regulation Commission, through its Board of Mechanical Engineering, administers the objective multiple-choice examination over a two-day schedule at designated testing venues. PRC has been moving licensure examinations toward computerized delivery. Candidates apply through the PRC online services portal.
Do I need work experience to take the Mechanical Engineer exam?
No additional work experience is required to sit for the Mechanical Engineer written tier. Candidates generally need a Bachelor of Science in Mechanical Engineering from a recognized program and must meet PRC eligibility requirements such as citizenship and good moral character.
