- Abstract
Cable-driven building elevators can be seen as a spring-mass system and, by means of Hooke's Law, we may quantify its oscillation period, resulting that the square of said period is directly proportional to the length of the wire [4]. We set upon ourselves the task to validate said results. We used the elevator of the CIT building found at Universidad del Valle de Guatemala, Phyphox app, Excel and Capstone programs for data analysis purposes. We recorded the perpendicular acceleration inside the elevator as a function of the time on all 11 floors after making it oscillate with a jump, obtaining the oscillation period of the system (elevator). Amongst the results, we obtained the correlation ratio R² = 0.98 of the linear regression applied in the graph relating the square of the period as a function of each level of the CIT Building, a value which validated the hypothesis. We reached the consensus stating that an elevator functioning by a spring-mass system, the square of the oscillation period is directly proportional to the length of the wire.
