DEVELOPMENT OF A REVIEWER MANUAL IN MECHANICAL ENGINEERING With Theories and 5,001 Solved Problems and Answered Questions (Elements) For Computerized Mechanical Engineering Licensure Examination
ABSTRACT. This project was proposed for the development of a reviewer manual in Mechanical Engineering (ME) with theories and 5,001 solved problems and answered questions (elements) for the computerized mechanical engineering licensure examination. The manual contains all the subject areas required in the curriculum prescribed and specified by the Professional Regulation Commission (PRC) through the Board of Mechanical Engineering (BME), covering Mathematics, Basic Engineering, Engineering Economy, Industrial Plant Design, Power Plant Design, Machine Design, Machine Shop Practice, ME Law, Contracts, and Professional Ethics. Problems and questions were developed and formulated based on the type of past examinations given by the Board of Mechanical Engineering Examiners. Solved problems and answered questions in the previous Licensure examinations are also included and presented in the reviewer manual. The manual is designed as a review material to be used by ME graduates who are preparing for the licensure examination and by ME graduating students who are taking in-house review program. Furthermore, this could be used by practicing mechanical engineers as a reference material. Key words: reviewer manual, mechanical engineering licensure examination,
Board of mechanical engineering, in-house review
INTRODUCTION Republic Act 8495, also known as the Philippine Mechanical Engineering Act of 1998, is an Act regulating the practice of Mechanical Engineering (ME) in the Philippines. Section 2 of Article 1 of the Act stipulates that “the State recognizes the importance of mechanical engineers in nation-building and development. Their talents, through sustainable human development, shall be promoted. Thus, the State shall develop and nurture competent, virtuous, productive, and well-rounded mechanical engineers whose standard of professional practice and service shall be excellent, qualitative, world-class, and globally competitive through regulatory measures, programs, and activities.” activities. ”

The Act states further in Section 12 and 13 of Article III that “all applicants for registration for the practice of Mechanical Engineering shall be required to undergo and pass a written technical examination as provided for in this Act. The certificates of registration for the practice of Mechanical Engineering shall be of three (3) categories and in order of rank: (a) professional mechanical engineer; b) mechanical engineer; and (c) certified plant mechanic.” One of the qualifications of applicants for mechanical engineer is stated in Section 15c, Article III of the Act: “Any person applying for examination and for a Certificate of Registration as mechanical engineer shall, prior to admission to the examinations, establish to the satisfaction of the Board that he/she holds the degree of Bachelor of Science in Mechanical Engineering from a university, school, college, academy, or institute duly constituted and recognized as such by the government.” Furthermore, Section 17b of Article III of the Act states: “The applicant shall pass a written examination on different subjects or group of subjects prescribed by the Board, and within the syllabi prepared by the Board with emphasis on power plant and industrial plant engineering, mathematics, engineering economics, economic analysis, laws and ethics, and machine design.” Moreover, the subjects in which the applicant for mechanical engineers shall be examined are as follows: 1) machine design, materials, and shop practice; 2) industrial and power plant engineering; and 3) mathematics engineering economics and basic engineering sciences. With the previously mentioned requirements to practice ME in the Philippines, ME graduates and applicants must be fully equipped and prepared before taking the licensure examination. It is the obligation of the school to prepare their graduating students and graduates before taking the board exams. Thus, the proponent decided to develop a reviewer manual for computerized licensure examination in Mechanical Engineering, designed and formatted according to the type of examinations given by Professional Regulation Commission (PRC) through the Board of Mechanical Engineering (BME). The manual contains theories and 5,001 solved problems and answered questions. Problems and questions were formulated in all subject areas based on the most frequently asked questions and given problems in previous examinations. This manual caters to ME graduating students who are taking “In-House Review Program” and for ME graduates who are preparing for the licensure examination. Most importantly, the manual can be a useful reference material for practicing engineers.
Main Objective of the Project This work was conducted to develop a reviewer manual for computerized licensure examination in ME, designed and formatted in accordance with the type of examinations given by the PRC through the BME. The manual contains theories 66
and 5,001 solved problems and answered questions and covers all the subject areas in the Mechanical Engineering curriculum prescribed by the BME.
Specific Objectives of the Project This project aimed to: 1. develop a reviewer manual in Mechanical Engineering containing 5,001 solved problems and answered questions and covering all the subject areas, from mathematics to power plant, as prescribed by the BME and Commission on Higher Education (CHED); 2. present theories for the corresponding solved problems and answered questions; 3. formulate problems and questions in all subject areas formatted to the type of examinations given by the BME; 4. present problems and questions on the subject areas that are similar to those commonly asked and given in the previous licensure examinations; 5. present the problems and questions previously given in the past board examinations; 6. provide a reviewer manual in mechanical engineering for graduating students who are taking in-house review program and for ME graduates preparing for licensure examination; and 7. provide a reference material for practicing engineers.
Significance of the Project The development of the review manual will enable the Engineering Department of Colegio de San Juan de Letran Calamba to have a review material in ME that can be used in the in-house review program for ME graduating students. It could also be used as a reviewer by ME graduates preparing for licensure examination and as a reference material by practicing engineers. This could likewise be the basis of other instructors or professors in developing a handbook or manual for their respective subjects. Lastly, the review manual could be used by other schools in preparing their graduating students and graduates for the ME licensure examination.

METHODOLOGY The manual is the compilation of theories and 5,001 solved problems and answered questions (elements) formulated by the author. It covers all subject areas from mathematics to power plant design. All pr oblems and answered questions are formatted according to the the type of past examinations given by the BME. Answered problems and questions given in the previous licensure examinations are also presented in this reviewer manual. To complete this reviewer manual, the following steps were executed: 1. Gathering and organizing data/materials; 2. Formulating and solving the problems and questions for each subject area; 3. Computer encoding of the data and notes available; 4. Printing and binding the guidebook; 5. Presenting the first draft of the guidebook to the Research and Development Department (R&DD) and Technical Committee; 6. Revising and printing; 7. Presenting the draft to the academic board; 8. Finalizing, printing, and binding; 9. Submitting the final copy of the reviewer manual to the RDD; and 10. Presswork.
