Project 11 (Video) [21 FP “Fluency Points”]: “Arbitrary Excitation” In a one-minute video, present an analysis of a real-life forced “arbitrary” 1-DOF vibration (due to a step forcing function) of a structure via experiment and theoretical calculations Description: In a video that lasts no longer than 60 seconds: • Identify or design a 1-DOF forced vibration of a structure in or around your house, where the external excitation is a step function that looks like: • Explain the phenomenon and the vibration behavior by: ◦ Conducting a simple experiment to capture the motion of the vibrating structure, and graphing the observed vibration in a displacement vs time plot; and: ◦ Performing a theoretical analysis and visualizing the solution in a displacment vs time plot, by using the “arbitrary” nonharmonic excitation theory. • Make concluding remarks that may include a comparison of the experimental and analytical results, sources of error, validity of your assumptions, etc. • Also reflect on your journey of making the video and what you've learned. Rules: • • • • • • Tips: • • • • Video must be in landscape mode Video must be less than 60 seconds long Must show your face Must voice narrate your explanation Video must be uploaded to YouTube Individual work Make it fun yet educational Shoot plenty of raw footage, then edit using a free software Speak close to the mic Make your YouTube video “unlisted” • • Test YouTube link before submitting on Gradescope See below for how to upload videos to YouTube and how to submit URL in Gradescope Requirements: Submit your Youtube URL on Gradescope only.
