In this experiment, a MacBook laptop with a built-in accelerometer and video camera is used to record synchronized data and video during an experiment measuring the free vibration of a cantilever beam.
The MacBook laptop will also be used to upload the experimental data to the earthquake engineering research data sharing archive, NEEScentral (https://central.nees.org). To maximize participation, it is recommended that the class be divided into smaller project teams.
Each team may conduct 1-2 experiments in the laboratory using the MacBook laptop. The data obtained during each team's experiments should be uploaded into different sections within NEEScentral. After the experiments are completed, the data can be downloaded and used by students to investigate basic dynamic properties of the cantilever beam.
