Today in 3rd period we started off by turning in the detecting decibles worksheet, the loudness worksheet, and the pair check from the previous day if it had not already been turned in. Then, we watched a video on how the Tacoma Narrows Bridge collapsed. After that, we watched a Mythbusters video on Rubens flame tube. Then, we broke out the palm pipes. Each of us received a different length pipe that, when hit on the palm of your hand, produced a note. Miley directed our class as we played a couple of songs. Finally, we proceeded to work on the sound lab that we will finish tomorrow.
QOD:
The Tacoma Narrows Bridge collapsed because the strong pulses of the wind caused the bridge to vibrate at its natural frequency. The bridge began to resonate. Eventually, the concrete cracked and it collapsed.
