Diseño y construcción de un banco de pruebas para la comprobación de la segunda ley de newton en el laboratorio de física de la FICM-UTA

Abstract

This technical project is focused on the design and construction of a test bench that will be used to perform physics tests focused on the verification of Newton's second law. To realize this machine was implemented the elimination of contact friction between components by generating fluid films, this film is generated by a device that was selected by comparing systems with respect to criteria such as cost, availability and properties; after the comparison is evaluated in order of priority by CAE software through the CFD system, therefore, the best option for pumping air has a flow rate of 4.6 cubic meters per minute, then proceeding to the design of the base of the pumping system and its fastening elements. An electronic system with infrared sensors was used for data collection and a 4x4 keypad was used for control, with programmable buttons for digital and power control as well as data input. Finally, with the structure assembled, the tests were performed, in which the operation of the equipment was verified, and experimental time data was recorded to obtain velocities and accelerations that were compared with analytical data in which errors of up to 12 percent were presented, which when compared with existing equipment on the market, it is shown that it is within an acceptable range
