The ABVE is designed to perform 3 experiments on the bridges: a study of the forces in bridge members when loads are applied, finding the resonant frequencies of the structures using vibrations from speakers positioned at either end of the bridge, and also using pulses of wind from a fan to further explore resonant frequency. The ABVE comes with two bridge kits students can build, one kit to build 3 unique truss bridge styles, and one kit for building a suspension bridge. The force sensors attach directly to the bridge members by sliding into square cutouts in each of the members so the forces in each member can be individually measured. A speaker is positioned at each end of the bridge support structure and transfers vibrations to the bridge. The fan is situated on its own secure tower and can be moved to different angles. An electrical housing with a convenient handle contains the display showing users what force readings they are getting and allows them to control the speakers and fan. The ABVE is powered by simply plugging it into a wall outlet.
