✦ Synopsis


A single-degree-of-freedom system with both a linear and a cubic non-linear spring term is examined. The system is shown to exhibit periodic and chaotic motions. The existence of chaos is discussed and possible qualitative explanations for the chaos are examined. It is shown that multiple static equilibria are not a necessary requirement for chaos to occur. Some introductory tutorial material is included in the presentation to assist engineering readers who may be unfamiliar with the subject.
