“…Other more complex oscillatory examples are the rotary spring or the physical pendulum. Although, both of them can be easily analysed for small perturbations and the solution is also a harmonic function with ω δ = √ k/ I for the rotary spring [6], and ω I = √ mgd/ I for the physical pendulum [7,8], where k is the rotary spring constant, I the inertia moment in both cases, m the mass of the physical pendulum, and d the distance from the hanging point to the center of mass of the physical pendulum. The oscillation period, T = 2π/ω, for all mentioned cases is resumed in table 1.…”

In this manuscript, a non typical kind of simple pendulum called Truncated Simple Pendulum is analysed to obtain its oscillation period, frequency, and angular frequency. It is easily derived that its motion can be viewed as the concatenation of two pendular movements with different lengths, contributing each one to half of the period of the complete oscillation. An analytical formulation is derived and corroborated with an experiment showing high agreement. This experiment could be interesting as a proposed exercise for the students or as a laboratory practical work. Besides, the gravity acceleration can be determined from each singular experiment and averaged to obtain it with lesser experimental error. In addition, it can be used to evaluate energy conservation theorem and small angle approximation (Law of isochronism) for the pendular oscillation. The level of the manuscript makes it appropriate for undergraduate students and introductory physics courses.

Comment on ‘Pendulum: the partial and global approach’

The paper Pendulum: the partial and global approach combines a historic introduction to the theoretical treatment of pendulum motion with presentation of data from measurements on a single pendulum. This comment focuses on the presentation and analysis of experimental data, and how the use of dimensionless variables in graphs would make use of the mathematical properties, placing the single measurement in a more general context, including mass-independence and the isochronism (for small angles). The concept of ‘effective weight’ used by Coelho is then discussed in relation to inertial forces and the principle of equivalence between inertial and gravitational mass.
