“…A construção civil, também faz parte dessa significância. Sendo assim torna-se importante que se verifique a constante elástica das espécies vegetais, pois essa propriedade física mede o nível de rigidez dos materiais (FERREIRA; RINO, 2006). Todos os corpos que são submetidos a uma força ou tensão sofrem deformação, porém alguns mais e outros nem tanto (Gomes et al 2015).…”

“…Some studies included corrections in order to take into account the influence of the spring mass on the oscillations of the spring-mass system [3,4]. Likewise, stud-ies of the behavior of the oscillations of systems constructed of plastic and non-helical springs have been carried out [5,6]. Previous studies have dealt with the influence of changing the natural length l 0 of the spring (for a fixed diameter) on the behavior of the elastic constant k, the angular frequency ω and the damping factor γ of the oscillations [7].…”

The simple harmonic motion of a spring-mass system generally exhibits a behavior strongly influenced by the geometric parameters of the spring. In this paper, we study the oscillatory behavior of a spring-mass system, considering the influence of varying the average spring diameter Φ on the elastic constant k, the angular frequency ω, the damping factor γ, and the dynamics of the oscillations. It was found that the elastic constant k is proportional to Φ-3, while the natural frequency ω0 is proportional to Φ- 3 / 2, and γ decreases as Φ increases. We also show the differences obtained in the value of the angular frequency ω when the springs are considered as ideal (massless), taking into account the effective mass of the spring, and considering the influence of the damping of the oscillations. This experiment provides students with the possibility of understanding the differences between theoretical models that include well-known corrections to determine the frequency of oscillations of a spring-mass system.

“…The characterization and mathematical formalism that determines the mechanical behaviour of this system are well defined and explained in several elementary physics texts [1]. In addition, generalizations have been made that involve the spring-mass correction [2] and the analysis of oscillatory phenomena under certain conditions, such as a mass on a spiral spring [3,4]. Thorough studies show that the mass of the spring influences its static and dynamic behaviour, so it is necessary to include the concept of equivalent spring mass 0143-0807/12/010219+11$33.00 c 2012 IOP Publishing Ltd Printed in the UK & the USA 219 in the oscillatory system [5,6].…”

The aim of this work is to analyse the influence of spring length on the simple harmonic motion of a spring–mass system. In particular, we study the effect of changing the spring length on the elastic constant k, the angular frequency ω and the damping factor γ of the oscillations. To characterize the behaviour of these variables we worked with a series of springs of seven different lengths, in which the elastic constant was found by means of the spring-elongation measurement and ω was obtained from the measurement of the oscillation period T of a suspended mass. The oscillatory movement was recorded using a force sensor and the γ value was determined by the fit of the envelope oscillations. Graphical analysis of the results shows that k, ω and γ decrease when the natural spring length increases. This experiment can be performed with equipment normally found in undergraduate physics laboratories. In addition, through graphical analysis students can deduce some relationships between variables that determine the simple harmonic motion behaviour.
