Elastic Stability of 3D Ideal Trusses

The contents of this paper reflect work that was conducted in the early 1960s in preparation of class notes for a graduate course on Elastic Stability taught in the Civil Engineering Department of MIT. This material is now well known and the presentation is not submitted as a new or original contribution but rather as a reflection of some work done that is related to the teachings of Professor Jerry Connor when he started at MIT. It is intended as an example of Jerry's impact since his early years on generations of students and young colleagues and an acknowledgement of our debt to him.
