“…The accelerometers embedded into smartphones have stable modes of data acquisition with a sampling rate reaching 100 Hz, which is discussed, in detail, in this study [11]. They have been designed to include the contribution of the gravity effect even if they are in a steady position.…”

The dynamic study of pendulum systems is considered an indispensable subject for physics and mechanics students in colleges and high schools. In this paper, a detailed methodology is given concerning the use of smartphones in pedagogical practical work for studying the dynamics of pendulum systems. Whereas, three aspects have been discussed through three cases concerning the study of the oscillatory motion, trajectories, and the energy aspect. Besides, some recommendations were provided regarding the process of data acquisition and curve-fitting processing to mitigate measurement errors. Experimental results exhibit a good agreement with theoretical results regarding the period of motion, trajectories, and mechanical energy. This makes the smartphone highlights a real opportunity to be a useful instrument to perform an overall study of the pendulum systems, the thing that was impossible without the intervention of professional equipment.

“…The smartphone's accelerometer measures the acceleration of the device's motion, including the amount of acceleration due to gravity. So, to measure the actual movement of the device, it was recommended to exclude the amount of gravity component from the measured acceleration data [5]. For this reason, a high pass filter was designed to remove the gravitational effect, as given in [15].…”

“…For this, practical work is an excellent way to give a close meaning to the theoretical concepts. Unfortunately, due to the lack of professional equipment [5], this type of laboratory experimentation is not within the hands of students, so they are only interested in the static study of beams such as deflection and buckling phenomena. For this purpose, this paper outlines the opportunity behind the use and exploitation of smartphones for educational purposes as an experimental instrument.…”

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.
