In this sense, the proposed project tries to pave the way from “apparently disconnected” concepts gained through previous studies toward the field of computational mechanics. On this basis, we study the motion of a particle along an arbitrary curve in space subject only to the gravitational field, the so-called sliding bead. Although this is a classic problem in mechanics, it has a substantial richness from a theoretical and practical point of view where the student reinforcing abstract skills and exploring different aspects of its numerical solution are allowed. Along this path, we start with the modeling process. This is followed by a stability analysis of the governing differential equations. Later on, we present a moderate introduction to classical numerical time integration by considering several numerical schemes and the well-known Matlab add-on Simulink. Finally, we present a brief discussion about how the proposed project allows articulating concepts of mathematics, mechanics, and computation in engineering programs of studies at horizontal and vertical levels.","PeriodicalId":39952,"journal":{"name":"International Journal of Mechanical Engineering Education","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47558686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the GFS method does not provide a clear guide on how to handle uncertainty, feasibility, and preference for design problems. Addressing this issue is crucial since the designer usually requires making assumptions to be able to propose functional solutions. The Given-Find-In Order To-Subjected To (GFIS) method and roadmap are here proposed to systematically state a design problem and requirements using fuzzy desirability functions to handle uncertainty, feasibility, and preference. The GFIS method lists the parameters, variables, specifications, restrictions, and preferences to facilitate the decision-making process. A comparative study was conducted with undergraduate students from Tecnológico de Monterrey enrolled in the course Design Methodologies. The students solved a band brake design problem before and after applying the GFIS method, and their performance was compared. The results showed a significant improvement in their decision-making ability, their capability to find feasible solutions, and the time required to make a design proposal.","PeriodicalId":39952,"journal":{"name":"International Journal of Mechanical Engineering Education","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43420915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It allows engineering students to work on real projects, with all the difficulties that arise in field testing, and to gain hands-on experience from the confrontation of practical situations and challenges, which presents positive outcomes regarding learning objectives and program appreciation. This article presents an engineering project developed by students for instrumentation and automation of an old manually operated torsion testing machine, for execution of accurate mechanical tests and reliable physical replications of real-world industrial processes on laboratory scale. An electrical resistive furnace is incorporated into the torsion testing machine to also allow hot torsion tests with controlled temperature. In addition to students’ skills development, this project yields a completely functional instrumented and automated torsion testing machine, with a controlled temperature electrical furnace and other features that have been used in Bachelor, Master, and Doctoral projects, laboratory classes, and new research.","PeriodicalId":39952,"journal":{"name":"International Journal of Mechanical Engineering Education","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46110107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hardened SKD11 steel has a high hardness of 58-62HRC, good wear resistance, and good toughness. Hard turning is an important process because manufacturers continually seek ways to manufacture their parts with lower cost, higher quality, rapid setups, lower investment, and smaller tooling inventory while eliminating non-value-added activities where Surface roughness is an important parameter determining the accuracy and quality of parts. In this paper, an analysis of the surface roughness of SKD11 steel in hard turning with mixed ceramic inserts is performed based on variables like cutting speed, feed, and depth of cut. The feed rate is the most significant parameter affecting the surface roughness in the machining process. Prediction of surface roughness considering the simultaneous effect of cutting parameters is very difficult. Here, a mathematical model is developed based on the simultaneous effect of depth, cutting speed, and feed rate. Moreover, the developed model is validated using different sets of cutting conditions and found in close agreement with experimental results.","PeriodicalId":39952,"journal":{"name":"International Journal of Mechanical Engineering Education","volume":"31 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80770634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, this study was conducted to examine the students’ views on nature of engineering at the Materials Science and Engineering department at University of Ioannina, through the views of first- and fifth-year students. 145 students participated in this research, 75 first-year and 70 graduate students. Participants were asked to complete a questionnaire with open-ended questions that required scientific knowledge, regarding Engineering and Science. After the collection of the questionnaires, statistical processing was carried out regarding the first and the last year student's views, as well as the prospective change of their views during the years of their study. The results of the study revealed that first-year students had already a formed view of engineering; however, their answers tended to be numerous, short and generally formulated, while a complete lack of knowledge on technical engineering issues was observed. At the same time, in elaborated questions that sought to explore their beliefs about nature of engineering, the students’ views were simple, vague, scientifically naive and in some cases non-existent. On the contrary, the fifth-year students seemed to have sufficient and satisfactory knowledge of the cognitive subject, with much more accurate and scientifically correct opinions, mainly regarding technical issues. However, their responses regarding nature of engineering simulated the first-year students, where it was found that the level of assimilation concerning nature of engineering is equally low.","PeriodicalId":39952,"journal":{"name":"International Journal of Mechanical Engineering Education","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47901887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Face to face and distance learning (teaching delivery models) are fundamental aspects of providing quality support to the students’ learning. One incredibly important aspect of students’ learning is to provide relevant industry-related projects and applications of relevant simulation software to mimic the systems. This paper develops students’ essential problem-solving skills and control strategies of fluid power systems in mechanical engineering through the Master of Engineering programs by employing Simulink, SimScape Fluid applications in Matlab software and Energy Plus with Design Builder. The main focus is to ensure that the students achieve the required skills of building fluid circuit models based on physical connections that directly integrate with appropriate symbols and modelling paradigms in fluid power applications to model the appropriate physical models to mimic the industrial fluid power projects selected. The basic ideas and content are to be delivered through weekly lectures and tutorial sessions, and the students’ skills in fluid power systems and software are developed and monitored through weekly workshops scheduled for all projects. The key outcomes of this study are the level of understanding of fluid power systems, development of simulation skills using the software indicated, interpretation of the results the students have obtained and validations of those results. The students must show they have developed appropriate problem-solving skills using simulation software, professional presentation and effective team-building skills. As the students develop appropriate problem-solving and engineering practice skills, their satisfaction and feedback rates improve significantly.","PeriodicalId":39952,"journal":{"name":"International Journal of Mechanical Engineering Education","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46481951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the current explanations found in undergraduate (and pilot-focused) textbooks can be inconsistent, often attributing the phenomena to the interaction between tip vortices at the ground. Others invoke the method of images to show that, when the flow is forced to have a straight streamline on the ground, ground pressure must increase. These must prescriptively choose an airfoil circulation. Meanwhile, a simple panel code can be used to show both that the lift on an airfoil in ground effect is significantly two-dimensional, and that the circulation about an airfoil near the ground is not constant. In particular, circulation will be found to grow as altitude decreases, magnifying the ground effect. A simple graphical panel method solver is provided, such that this exercise is accessible to students without the longer task of writing a panel code for themselves. This exercise can provide students with greater insight into the Kutta condition, the method of images, and panel methods themselves. The resulting streamline pattern can also be used to explain the phenomenon to more general audiences, by observing the relationship between lift and streamline curvature.","PeriodicalId":39952,"journal":{"name":"International Journal of Mechanical Engineering Education","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43492188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
