Idea[edit | edit source]

A "shaker table" is an oscillating platform that can be used to test structures by simulating earthquakes. These platforms can also be used to demonstrate physics concepts like resonance. A physics professor at Howard Community College requested that a shaker table be developed for instructional use. It was also used as a kid-friendly STEM demonstration at the 2014 Science & Engineering Festival in Washington, DC.

Conceive[edit | edit source]

Not applicable - Conception has been informally described above. Students start with design or implement.

Design[edit | edit source]

  • Manual shaker table - In spring 2014, students will build(implement) the design documented here
  • Automatic shaker table - As of spring 2014, students are actively working on designing a single-axis, variable frequency, Arduino-controlled shaker table that does not require manual operation. The design documentation will be posted here when complete.

Implement[edit | edit source]

  • Manual shaker table - build the design mentioned above
  • Automatic shaker table - students to build after design is complete

Operate[edit | edit source]

  • Manual shaker table - test and demo for 2014 National Engineers Week in February at Howard Community College
  • Automatic shaker table - demo at USA Science & Engineering Festival, and used by physics/engineering faculty at HCC
