PRC Mechanical Engineer study guide
PRC Mechanical Engineer · Work through your exam, one topic at a time.
The Mechanical Engineer Licensure Examination is the Philippine board examination for entry into the mechanical engineering profession, administered by the Professional Regulation Commission (PRC) through the Professional Regulatory Board of Mechanical Engineering. It is intended for graduates of mechanical engineering programs who need a license before taking responsible charge of mechanical design, installation, operation and power plant work, and before signing and sealing mechanical plans. Candidates should expect three broad subject areas: Machine Design, Materials and Shop Practice; Industrial and Power Plant Engineering; and Mathematics, Engineering Economics and Basic Engineering Sciences. The PRC material summarised here does not publish per-subject weighting, item counts, time limits or a passing percentage, so treat figures quoted elsewhere as unverified and confirm them against the current PRC examination schedule and the PRC Citizens' Charter before planning. The PRC Mechanical Engineer study guide has 3 sections and about 1,694 words.
01Machine Design, Materials and Shop Practice
Machine Design items reward the candidate who can move cleanly from a free-body diagram, to a stress state, to a geometry decision. The working toolkit is: static failure theories (maximum shear stress and von Mises for ductile metals; maximum normal stress and Mohr-Coulomb for brittle materials), combined loading, stress concentration factors, fatigue assessment (endurance limit with its modifying factors, then Soderberg, Goodman or Gerber diagrams), and the standard routines for shafts, keys, belts, clutches, gears, springs, bolted and welded joints, and bearings.
729 words, about 4 min02Industrial and Power Plant Engineering
Expect three clusters. Thermodynamics and cycles: properties of steam, the Rankine cycle with reheat and regeneration, boiler efficiency by the direct and indirect (heat-loss) methods, and combustion stoichiometry.
341 words, about 2 min03Mathematics, Engineering Economics and Basic Engineering Sciences
This is the highest-yield domain for speed practice. The recurring topics are algebra and simultaneous equations, quadratic and polynomial behaviour, plane and spherical trigonometry, analytic geometry (lines, conics, distances), differential calculus (maxima-minima, related rates, curvature), integral calculus (areas, volumes, centroids, work), differential equations (separable, linear first-order, second-order with constant coefficients), matrices and determinants, complex numbers, probability and counting, and descriptive statistics including mean, median, standard deviation and the normal curve.
