The Faculty of Mechanical Engineering, University of Žilina, carries out its activities in the environment of other Slovak faculties based on mechanical and production engineering.The Faculty deals with standard disciplines (such as measurement, automation, industrial engineering, technological engineering, mechanic and strength, design and machine elements) and with specific engineering disciplines (such as machinery maintenance engineering; railway vehicles; engines and lifting equipment; heat and hydraulic machines). The specific engineering disciplines are unique for Slovak faculties. Transport technology and transport engineering are characteristic for the Faculty.
The engineering students understand the engineering concepts effectively when they conduct the experiments in the laboratory. Hence, laboratory is as important as theory; however, the ill-equipped laboratory facilities affect the students’ learnability. The virtual laboratories may help the students overcome the problems faced by them in the conventional laboratory. In India, educational activities during the middle of the semester were affected due to lockdown related to COVID-19. However, the theory classes were conducted online, and educational institutions are finding it difficult to complete the laboratory experiments due to closure of colleges for the students due to COVID-19 pandemic. Hence, we have conducted a faculty development programme for the engineering college faculty members on mechanical engineering virtual laboratories. Similarly, we have trained the mechanical engineering students on fluid mechanics virtual laboratory. We have taken feedback from the participants of these virtual laboratory training programme and analysed it. From the analysis we have observed that more than 90 per cent of the participants were happy about the virtual laboratory and they expressed that their learning process improved with virtual laboratory experiments. Also, they felt that the virtual laboratories can be used till the COVID-19 pandemic issues are solved. Since the vaccine for COVID-19 is not available yet, the virtual laboratories will help the mechanical engineering students to conduct the laboratory experiments for the academic year 2020–2021.

This is an overview of current research in origami applied to mechanical engineering. Fundamental concepts and definitions commonly used in origami are introduced, including a background on key mathematical origami findings. An outline of applications in mechanical engineering is presented. The foundation of an origami-based design procedure and software that is currently available to aid in design are also described. The goal of this review is to introduce the subject to mechanical engineers who may not be familiar with it, and encourage future origami-based design and applications.

We developed a distributed-parameter model (partial differ-ential equations and associated boundary conditions) that de-scribe the coupled torsion and bending motions of the Digital Micromirror Device (DMD) using the extended Hamilton prin-ciple. The work done by the electrostatic field is expressed in the form of a potential energy. It is found that coupling between the torsion and bending motions appears in the boundary con-ditions. The nonlinearity is mainly due to the application of the electrostatic forces and moments. Nonlinear terms appear only in the boundary conditions. The developed model provides a basis for a thorough study of the static and dynamic behaviors of the electromechanical device. The static response of the DMD for different DC loads shows the occurrence of pull-in (snap-down) instability at critical voltage values corresponding to the collapse of the yoke to mechanical stops. Estimates of the voltage, an-gle, and deflection at pull-in are given. The dynamic behavior of the DMD is analyzed by plotting the natural frequencies versus the applied DC voltage. We conducted a study of the sensitivity of the static and dynamic behaviors of the micromirror to vari-ations in the geometric parameters of the DMD. It is found that the thickness and width of the hinges are the key parameters in-∗Address all correspondence to this author

Abstract This review presents various types of epoxy resins and curing agents commonly used as composite matrices. A brief review of cross-linking formation and the process of degradation or decomposition of epoxy resins by pyrolysis and solvolysis is also discussed. Mechanical engineers are given a brief overview of the types of epoxy resin, which are often applied as composite matrices considering that they currently play a large role in the research, design, manufacturing, and recycling of these materials.

For upper-level undergraduate engineering courses in Mechanical Behavior of Materials. Mechanical Behavior of Materials, 4/e introduces the spectrum of mechanical behavior of materials, emphasizing practical engineering methods for testing structural materials to obtain their properties, and predicting their strength and life when used for machines, vehicles, and structures. With its logical treatment and ready-to-use format, it is ideal for upper-level undergraduate students who have completed elementary mechanics of materials courses.
A centuries-old vision of a mechanical volcano has finally erupted into reality, as two University of Melbourne engineering students recreated a design first imagined in 1775 by volcanology enthusiast Sir William Hamilton。 Drawing from an 18th-century watercolor and a preserved sketch, they used modern tools like LED lighting and electronic systems
