This article proposes a systematic approach for the preliminary design of a hypersonic airbreathing (scramjet) vehicle within an academic context. The goal is to serve as an educational tool, focusing on teaching students the fundamental physical concepts behind scramjets. The article provides essential equations for generic scramjet designs while explaining the simplifications made from an academic perspective. It demonstrates the use of spreadsheets as a user-friendly tool to modify parameters and observe the behavior of shock waves. The article outlines a four-step procedure. It includes estimating atmospheric properties, designing the supersonic inlet, calculating combustion chamber parameters, and determining postcombustor properties. An academic exercise illustrates these steps for a scramjet flying at a specific velocity and altitude. The results show that this procedure, combined with spreadsheets, enables a rapid prediction of thermodynamic properties, enhancing the understanding of the fundamental physics behind hypersonic airbreathing vehicles.

Using PowerPoints slides (PPT) to deliver lectures has become the norm and common practice in academia over the last decade. Despite the benefits of PPT in providing smooth presentations and helping to prompt the presenter, the use of slides in engineering teaching has its own drawbacks. By using slides in teaching, the information will be provided in a discontinued and very abstract format. However, as a matter of fact, students mainly depend on lecturing slides in their learning and only use the slides to prepare for their exams. Students rarely read beyond what is given in the slides or refer to the reading list for more in-depth knowledge. This creates a gap in knowledge, affects the overall student experience and, to a certain level, affects graduate employment. In this paper, we review a pilot experiment to test a new teaching theme in engineering with no PPT slides. This was implemented for a Level 4 module, Mechatronics 1, which is a newly developed module in the Mechanical/Marine Engineering programmes at Liverpool John Moores University, Liverpool, UK. The outcome of this practice is evaluated with the focus on student views, assessment results, and overall assessment of this style of teaching.
在过去的十年中,使用 PowerPoints 幻灯片(PPT)进行授课已成为学术界的常规和 普遍做法。尽管 PPT 有助于提供流畅的演示和帮助提示演讲者,但在工程学教学中使用幻灯片也有其自身的缺点。在教学中使用幻灯片,所提供的信息将是不连续的和非常抽象的。然而,事实上,学生在学习中主要依赖于幻灯片,他们只是利用幻灯片来准备考试。学生很少阅读幻灯片以外的内容,也很少参考阅读书目以获得更深入的知识。这就造成了知识上的差距,影响了学生的整体学习体验,并在一定程度上影响了毕业生的就业。在本文中,我们回顾了一项试点实验,以测试一种不使用 PPT 幻灯片的工程学新教学主题。该实验在英国利物浦约翰摩尔斯大学机械/海洋工程专业新开发的 4 级模块 "机电一体化 1 "中实施。对这一做法的成果进行了评估,重点是学生的观点、评估结果以及对这种教学风格的总体评价。

This article suggests the hydraulic analogy technique as a cost-effective approach for flow visualization in fluid mechanics, particularly in dealing with challenges related to supersonic flow, such as shock waves and flow past wedges. The project-based learning approach is adopted to engage students in the study effectively. This active learning method allows students to actively participate in research activities, from setting project goals to designing and executing experiments. The article highlights the positive impact of project-based learning on students’ learning outcomes through internal and external evaluations. The study shows that project-based learning enhances technical competence and encourages a lifelong passion for learning. The cost-effectiveness of the hydraulic analogy method inspires neighbouring academic institutions to consider similar approaches, further promoting the use of practical and affordable solutions for flow visualization experiments.

The great demands for computational fluid dynamics (CFD) practitioners in industry have motivated universities to integrate CFD courses into undergraduate curricula. This article introduces a learning-centred CFD course that aims to train critical users of commercial CFD codes. The main features of the course include a project-based approach to learning and assessment-guided learning activities, both scaffolded by technologies. The implementation of the course is informed by contemporary pedagogical theories that encourage students to have the ownership of their own learning and constructively build their knowledge in an inclusive and supportive learning environment. The students upon completing the course have developed a conceptual understanding of the CFD principles and the importance of performing CFD simulations in a critical way, making them ready for more advanced CFD learning and practices. Course evaluation based on feedback from various sources demonstrates that the learning-centred approach is the key to the success of the course.

Social constructivism is considered the main driver of curriculum overhaul for the new set of learning in the digital age. Implementation of cost-effective solutions of social constructivism in higher education is a challenge. The paper circumnavigates around the principle and practice methods and implemented in a module design for robotics teaching to students from diverse academic backgrounds and familiarity levels. A gap analysis between the current practices of a generalized module design and a social constructive approach revealed the specific areas for a focussed approach to consider. Such strategies are employed in the module redesigning strategy and found cost-effective and impactful in Engineering higher education. The designed module is presented to engineering students in an integrated robotics education in the context of control, communication, sensing and biomechatronics. Multiple implemented innovations for social constructivism in different aspects of the module have not only made it a popular option among engineering students but also resulted in better engagement, student achievement, inclusivity, and resource utilization.

The paper is devoted to the line integral topic belonging to the section of vector calculus in Mathematical Analysis applied to the undergraduate Mechanical Engineering program. An efficient way of teaching line integrals is proposed and developed based on the elementary work/force principles. By this way, the mathematical concept of the line integral is supposed to be learned in harmony with the elementary mechanics to appreciate its diversity and to set up the right idea about the scientific area covered by Mechanical Engineering and related academic and technical fields. In terms of practical training, the research also offers two new techniques of analytical calculus for line integrals containing singularities and provides a new coherent engineering approach to deal with vector fields as integrands in line integrals.

Integrating low-cost fused filament fabrication 3D printing as a foundation for learning 3D modelling is explored. This method blends traditional computer aided design (CAD) instruction with additive manufacturing possibilities. Experimental results demonstrate increased comprehension speed and reduced learning time. This hands-on approach empowers students by enabling direct engagement with the modelling process. Analogous to reverse engineering, the strategy instructs engineering students from final product to model creation, closing the gap between theory and practice. Incorporating 3D printing bridges this divide, enhancing understanding, creativity and problem-solving. The study underscores technology's influence on learning strategies, aligning with the surge of 3D printing in education. Results link advanced design technology usage to improved student performance, with 3D-printed materials yielding 45% higher grades and 30% faster task completion. This study advocates curricular advancement for design-focused careers through enhanced technology integration and favourable 3D printing model reception.

A unified educational mobile application to aid in teaching solid mechanics using interactive Mohr's circle 利用交互式莫尔圈辅助固体力学教学的统一教育移动应用程序

The interpretation and visualization of engineering problems are complex. Therefore, engineers have always developed graphic procedures to solve these problems, one technique being Mohr's circle. The study of geometric properties of the cross-sections, plane stress, and plane strain are some applications of such techniques in Solid Mechanics. In practically all literature adopted in undergraduate courses on these topics, the efforts of authors to teach with the greatest clarity are remarkable, using all possible resources in books, with very well-designed graphics. However, concerning Mohr's circle, the mental visualization of some movement is needed, be it the rotation of points on the circle, the rotation of the cross-section, the axes, or the differential element. This need makes such topics ideal to be taught through interactive animations, impossible in books. Computer programs about these subjects do exist, however, with reduced user interactivity. Thus, this work presents a new unified mobile application with several useful interactivity features for teaching plane stress, plane strain, and moment of inertia in engineering courses, using Mohr's circle. The application is developed in Java programming language, using Android Studio software. The graphical environment was developed with the aim of being a didactic and intuitive way to study and learn about cross-section properties, plane stress, and plane strain. The results provided by the application are compared with examples from the literature, presenting accurate responses, with easy visualization and interpretation. The usage of the program makes studying the initial concepts of solid mechanics and Mohr's circle enjoyable for engineering students.
工程问题的解释和可视化非常复杂。因此,工程师们一直在开发图形程序来解决这些问题,莫尔圆就是其中一种技术。研究截面的几何特性、平面应力和平面应变是此类技术在固体力学中的一些应用。实际上,在有关这些主题的本科课程中采用的所有文献中,作者都在努力以最清晰的方式进行教学,并利用书本中所有可能的资源和精心设计的图形。然而,关于莫尔圆,需要在头脑中想象一些运动,无论是圆上点的旋转,还是截面、轴或微分元素的旋转。这种需要使得这些主题非常适合通过交互式动画进行教学,而这在书本上是不可能实现的。然而,关于这些主题的计算机程序确实存在,但用户互动性较低。因此,本作品介绍了一种新的统一移动应用程序,它具有多种有用的交互功能,可在工程课程中使用莫尔圆教授平面应力、平面应变和惯性矩。该应用程序使用 Android Studio 软件,以 Java 编程语言开发。开发图形环境的目的是以说教和直观的方式研究和学习截面特性、平面应力和平面应变。应用程序提供的结果与文献中的例子进行了比较,呈现出准确的反应,易于可视化和解释。该程序的使用使工程专业学生能够愉快地学习固体力学和莫尔圆的初步概念。

Therefore, engineers have always developed graphic procedures to solve these problems, one technique being Mohr's circle. The study of geometric properties of the cross-sections, plane stress, and plane strain are some applications of such techniques in Solid Mechanics. In practically all literature adopted in undergraduate courses on these topics, the efforts of authors to teach with the greatest clarity are remarkable, using all possible resources in books, with very well-designed graphics. However, concerning Mohr's circle, the mental visualization of some movement is needed, be it the rotation of points on the circle, the rotation of the cross-section, the axes, or the differential element. This need makes such topics ideal to be taught through interactive animations, impossible in books. Computer programs about these subjects do exist, however, with reduced user interactivity. Thus, this work presents a new unified mobile application with several useful interactivity features for teaching plane stress, plane strain, and moment of inertia in engineering courses, using Mohr's circle. The application is developed in Java programming language, using Android Studio software. The graphical environment was developed with the aim of being a didactic and intuitive way to study and learn about cross-section properties, plane stress, and plane strain.

Graduate employability is a major focal point of higher education. Designing curricula that equip graduates with the skills and attributes necessary to gain and retain employment is a challenge for Universities worldwide. This article investigates the perception differential between students, academics, and industry professionals. The aim is to identify the relevant skills and attributes to facilitate the transition of mechanical engineering graduates from education to employment. The results establish an upper second-class degree as the most desirable qualification. Studying a professional-body accredited course and being a student member of a professional institution are seen as crucial, despite the latter not being recognised as such by students. Significant differences are identified in the importance of Information Technology skills and software packages, with an institutional bias identified amongst academics. Lastly, the key skills and attributes to secure graduate employment are determined, with striking differences between industry professionals and students, the former desiring a personal and professional attitude and professional conduct above all else, the importance of which is underestimated by students. The findings provide novel insights into employability skills for mechanical engineers, and it is envisaged they may contribute to aligning engineering curricula with employer expectations, allowing graduates and academics to identify key employability skills and attributes, and improving graduate employment.
毕业生的就业能力是高等教育的一个主要焦点。如何设计课程,使毕业生具备获得和保持就业所需的技能和特质,是全球大学面临的一项挑战。本文调查了学生、学者和行业专业人士之间的认知差异。目的是确定相关的技能和特质,以促进机械工程专业毕业生从教育到就业的过渡。结果表明,二等以上学位是最理想的学历。学习专业机构认可的课程和成为专业机构的学生成员被认为是至关重要的,尽管后者并未得到学生的认可。在信息技术技能和软件包的重要性方面存在着显著差异,学术界存在着机构偏见。最后,确定了确保毕业生就业的关键技能和特质,行业专业人士和学生之间存在显著差异,前者希望个人和专业态度以及职业操守高于一切,而学生则低估了其重要性。研究结果为了解机械工程师的就业技能提供了新的视角,预计将有助于使工程学课程与雇主的期望相一致,使毕业生和学术界能够确定关键的就业技能和特质,并提高毕业生的就业率。
