Tensegrity: String to Stand On

Overview

The purpose of this project is to build and test a magnetic tensegrity table and determine the critical (maximum) load the table can hold before it becomes unstable; along with how the positions affect the results. The table was constructed using popsicle sticks, “J” brackets, cardboard discs, strings, and magnets. To test the strength, weights were added gradually to the top surface, one quarter at a time, until the table became unstable and failed. This was repeated for 3 different locations (center and the 2 opposing ends). The table held more weight at the center. When the weight was near the edge, the table became unstable sooner because of the added “turning/twisting” force (Torque). This experiment highlights a tensegrity structure and demonstrates that load placement is important for the stability of these structures. Understanding how forces act in these systems helps engineers design safer, stronger, more lightweight structures and innovative devices that use tensegrity.
