Determination of springs constant by Hooke’s law and simple harmonic motion experiment

Abstract

This study aims to calculate the spring constants of two types of stainless using Hooke's Law principle and simple harmonic motion methods. Two types of springs (spring I and II) with different sizes in diameter have spring constant k values of 24 N/m and 5.4N/m, respectively. Based on the experiment and calculation, the spring constant of spring 1 calculated by Hooke's Law and the simple harmonic motion experiment has an average value of 23.22 N/m with an error of 3.24% and 23.06 N/m with an error of 3.90%. On the other hand, the spring constant of spring 2 calculated by Hooke's Law and the simple harmonic motion experiment has an average value of 5.47 N/m with an error of 1.44% and 5.32 N/m with an error of 1.48 %. Hence, we concluded that the determination of spring constant using Hooke's Law has better accuracy.
