Lecture 4: Infinitesimal rigidity, tensegrities, stresses, duality, Maxwell-Cremona theorem, locked linkages, carpenter's rule theorem

Page 2: Tensegrities: bars, cables, struts, infinitesimal rigidity, connection to linear programming, stress, equilibrium

You can look at an example of Buckminster Fuller's tensegrity sculptures, the Sixty Strut Tensegrity Sphere.
You can look at many of Kenneth Snelson's tensegrity sculptures on his webpage.
George Hart has a webpage describing how to build your own tensegrity.

These are rough, personal lecture notes handwritten by Erik Demaine used during lecture. Their primary purpose is for reading/review by students of the class. Accessibility
