I. IntroductionDesign is one of the most important engineering functions for it is through design that new products and processes are born and that old ones are improved. Design requires a breadth of knowledge extending over many areas, and a sound analytical ability. It requires an ability to recognize the phenomena involved and to synthesize an integrated solution. Design requires sound engineering judgment as well as a good grasp of the underlying basic science and mathematics. Machine design is the process of engineering design. A machine is made up of mechanisms that work together to satisfy the requirements of what the machine needs to accomplish. Mechanisms can still be used independently, such as an umbrella, but cannot accomplish what a machine can because a machine controls energy in addition to motion. Machine design takes into account kinetics and kinematics, which deal with motion and the forces on an object in motion. Machine design is applied through a specific process including determining what the machine needs to do, benchmarking and defining goals and requirements, brainstorming, evaluating and selecting from the different options, creating an in-depth design, creating and testing a prototype, and finally manufacturing the machine. This course aims to integrate the knowledge that you have gained earlier in the qualification and focus your analytical skills towards synthesis of solutions by working through the design of several simple, commonly used devices.Design is the process of conceptualization, analysis, evaluation and verification of the form and function of products and systems. Good design engineering requires a deep understanding of customer needs, service environments, user processes, and requirements, industry standards, materials, manufacturing processes, and tolerances. Computer-aided design (CAD) systems are often employed to facilitate design engineering work, such as calculations, modeling, and simulations.In this study, the researchers aimed to find out the difficulties of Mechanical Engineering students of NEUST in taking Machine Design subject as identified by the respondents.
II. MethodologyThe researchers used the descriptive method of research. The respondents were chosen through purposive sampling. Calderon (1993) cited that purposive sampling is determining the target population, those to be involved in the study. The respondents were chosen on the basis of their knowledge of information desired.Respondents of the StudyStudents from the College of Engineering, Mechanical Engineering Department of Nueva Ecija University of Science and Technology during first and second semester of school year 2014- 2015 and who take Machine Design subjects were selected as respondents. These consisted of 55 B. S. Mechanical Engineering students selected on the basis of their knowledge about Machine Design subject.Research InstrumentA self-made questionnaire was the main tool in gathering data. The researchers divided it into three sets.Set A, consists of questions aimed to determine the nature of subject.Set B, consists of questions aimed to determine the teaching strategy of professor.Set C, consists of questions aimed to determine the assessment of the curriculum.Data Gathering ProcedureUpon the approval of the consultant, questionnaires were reproduced and distributed to the respondents. The distribution if questionnaire was conducted on February 26, 2015. The data obtained from the questionnaires was carefully tabulated and interpreted.Statistical Treatment of the DataThe following statistical tools will be used to describe and easily understand the results and other relevant findings in the study.For the descriptive presentation of variable, frequency, respondents, total number of respondents and weighted mean will be used. The formula is shown as follows.
Where:WM is the weighted meanF is the frequencyn is the number of respondentsn is the total number of respondentsThe respondents will rate each statement according from scale of 1-5 by placing a check mark on the box that corresponds to their answers.Set A (Nature of Subject)

IV. SUMMARY AND CONCLUSIONThis chapter presents the summary of the findings of the study and the conclusions drawn.SummaryThis study attempted to determine the difficulties of Mechanical Engineering students in taking Machine Design subject.A total of 55 Mechanical Engineering students (30 4th year and 25 5th year students) served as the respondents of the study. The investigation used the descriptive survey method. Frequency, number of respondents, total number of respondents and the weight mean were used as statistical treatment. The study utilized questionnaire in gathering data.Conclusion1. The researchers respondents are 4th and 5th year. Most of the respondents are 19-21 years old.2. Majority of the 4th year me students find solving problem as very difficult in nature of machine design. Content to memorize, formulae, solving and calculating problems are difficult for 5th year ME students.3. Majority of the ME 4th and 5th year students agreed on the teaching strategy of the professor which are practical work approved, understanding explanation of concept, teaching being friendly and given examples simpler than class exercises. Some of the 5th year ME students disagreed on teacher being friendly.4. ME students from 4th and 5th year find difficult in the curriculum or assessment of the subject such as following textbooks, examinations and syllabus content.5. The researchers conclude that the ME students find difficult in taking machine design.
