    Study Notes

    • The text describes an experiment to investigate the resistance of different constructions to vibrations that simulate earthquakes.
    • Two cubes, A and B, are constructed using jelly beans and large sticks.
    • Cube B is built using a "Pombaline cage" structure, which is a reinforced construction method developed after the devastating Lisbon earthquake of 1755.
    • The "cage" structure consists of vertical elements (uprights), horizontal elements (crossbars), and diagonal elements (braces).
    • The cubes are placed on a jelly surface and shaken laterally with low intensity for a few seconds, then shaken again with high intensity for a few seconds.
    • Deformations in the shape of the cubes during shaking are observed and recorded.
    • The experiment is intended to demonstrate the effectiveness of the Pombaline cage structure in resisting earthquake vibrations.
    • The Lisbon earthquake of 1755 caused significant damage to buildings and led to the development of new, more robust construction methods.
    • The Pombaline cage structure is named after the Marquês de Pombal, who ordered its use in rebuilding Lisbon after the earthquake.
    • The experiment described in the text is a simple way to demonstrate the principles of earthquake-resistant construction.
