“…Vibration analysis of beams is considered one of the areas concerned with laboratory experiments, which is a necessary skill for physics students, especially for mechanical and civil engineering students [3,4]. Due to the complexity of beam dynamics during theoretical courses, students do not have the ability to attain the full comprehension of dynamic concepts such as natural frequency and its relation with beam properties and boundary conditions.…”

Studying the dynamics of beams is considered an indispensable field for mechanical and civil engineering students. This paper describes, in detail, the use of smartphones in educational practical works to determine and examine the dynamic characteristics of beams subjected to free vibration. Where the smartphone is equipped with a mobile application to acquire the vibration data of the given beams and store it for processing. Three cases have been discussed, in which three types of boundary conditions have been presented. Also, a discussion was presented to show the influence of boundary conditions and material/geometrical properties of beams on the vibration damping of the system. In addition, some recommendations have been stated regarding the data collection and the processing step to mitigate the measurement errors. Experimental results show an agreement with theoretical results regarding the natural frequency and equivalent mass of the beam system which make the smartphone an alternative instrument to teach dynamic vibration of beams in case of the non-availability of professional equipment.

Structural dynamics is an essential aspect of mechanical engineering and a key module in the master's program in automotive engineering at the Universidad Autónoma de Nuevo León. Since this discipline requires a strong theoretical foundation coupled with significant practical application, it is essential to provide students with the necessary tools and content to gain a comprehensive understanding of the subject through engaging and applied case studies. This article presents the teaching methodology of a structural dynamics course, incorporating practical real-world cases that cover the most crucial components of the syllabus. Simulation tools and numerical analysis are applied through the course as support. Additionally, experimental activities are designed to complement the theoretical knowledge, ranging from simple student-conducted experiments to more complex laboratory activities involving specialized equipment and real-life field measurements. The discussion highlights how this approach is more engaging and practical for students, aiding their comprehension and application of theoretical concepts.
