Description:

This demonstrates that building shake during a earthquake at resonance.

Ingersoll Museum

Setup:

  1. No Setup

Cautions, Warnings, or Safety Concerns:

  1. Handle may become loose

Demonstration: Buildings of various length are put on springs that are attached to a movable platform. A person rotates the handle and moves the platform to simulate the earthquake. The person then observes that different length buildings shake(or don't shake)depending on the intensity of the earthquake. This is to demonstrate that a building will shake when it is at its resonance frequency and that longer buildings have a lower resonance then shorter ones.
